U-verse for BUSINESS? : 2Wire 3600HGV bridge mode? or another AT&T supported VDSL modem?

I am having trouble properly configuring this AT&T 2Wire 3600HGV modem for my network. Maybe someone is aware of a different firmware for this product?

 

I am completely aware of how to setup the DMZ mode & router behind router setup in these boxes but that is NOT the point. (We have supported firewalled networked equipment working that has all the bells & whistles including QoS)

 

In the event of a factory reset of the AT&T 2Wire VDSL modem at this business, I want to properly insure the following business requirements are met:

- DHCP - OFF (at min, it appears you must leave one available?)

- WiFi - OFF (Yes this can be turned off, but bridging it always insured it was turned off in the past. ON is a security concern among just bad business i.e. conflict with other business WiFi, employees might see/use this non-content filtered WiFi, etc etc)

- & passing off internet service needs to be easy to another networked supported OUTSIDE of AT&T firewall. (I'm NOT asking for AT&T support on this, but in the bridge DSL world, this was EASY)

- if bridging this 2Wire is NOT an option, backing up the configuration settings would be a nice alternative but that is not available as well?

 

Bridging the old DSL modems always worked nicely but the 2Wire 3XXXHGV line appears to be the ONLY ones to support the AT&T VDSL Max Turbo speeds. 24Mbps down / 3 Mbps up which we use not only for normal business operations (credit cards, business email, web based training, etc) but this high speed is required to view onsite security video (3Mbps up) and offer customers FAST free WiFi!

 

AT&T U-Verse offers the right price, contract, speed, internet package & installers to properly handle our resturant locations company's data needs but I'm struggling with the their "business" support of this 2Wire VDSL modem product. We ONLY use the internet, no TV (not legally available for restaurants, yet). No Voip because POTS is our reliable backup. So it's just the internet service ...

 

For coverage on AT&T Uverse, we have over 50 locations lit up like a Christmas tree but sadly business support on this product is driving me nutz! Maybe because I now see this is listed under "Residential Gateway"? Is this AT&T 2Wire VDSL modem product not meant for business? Is anyone aware of another supported AT&T VDSL modem or a different 2Wire firmware available? Official AT&T support has me running in circles (AT&T U-verse support > AT&T Connecttech > AT&T Connecttech360 > AT&T U-verse support, rinse, repeat)  

 

help?

There is no true bridge mode on the 2Wire routers.  However, you can still configure it such that almost all functions of your own router will work properly.

 

1. Set your router's WAN interface to get an IP address via DHCP.  This is required at first so that the 2Wire recognizes your router.

2. Plug your router's WAN interface to one of the 2Wire's LAN interfaces.

3. Restart your router, let it get an IP address via DHCP.

4. Log into the 2Wire router's interface.  Go to Settings -> Firewall -> Applications, Pinholes, and DMZ

5. Select your router under section (1).

6. Click the DMZPlus button under section (2).

7. Click the Save button.

8. Restart your router, when it gets an address via DHCP again, it will be the public outside IP address.  At this point, you can leave your router in DHCP mode (make sure the firewall on your router allows the DHCP renewal packets, which will occur every 10 minutes), or you can change your router's IP address assignment on the WAN interface to static, and use the same settings it received via DHCP.

9. On the 2Wire router, go to Settings -> Firewall -> Advanced Configuration

10. Uncheck the following: Stealth Mode, Block Ping, Strict UDP Session Control.

11. Check everything under Outbound Protocol Control except NetBIOS.

12. Uncheck NetBIOS under Inbound Protocol Control.

13. Uncheck all the Attack Detection checkboxes (7 of them).

14. Click Save.

 

Your router should now be able to route as if the 2Wire was a straight bridge, for the most part.

 

Inbound port 22 might be blocked, and inbound ports 8000-8015 might also be blocked, and there's nothing that can be done about it.

 

This is how I have my 2Wire configured, and I have a Cisco 2811 behind it doing IPSec, IPv6 tunnels, etc.

For the guest network you need to leave the DHCP range for it at the default of 10.0.1.x. That puts the guests on a separate network from your computers which is what you want.

Ahhhh.....so when I select the router mode from DHCP to DHCP and NAT and it defaults to the 10.0.1.2 to 200 (away from the 192.168 xxx then that is for the Guest Network only and leaves our home network on the 192.168 xxx

 

Then all Ihave to do is enabel the Guest Network box and assign a name and password?

 

I mistakenly though that by going with the router mode of DHCP and NAT... with the default 10.0.1 xxx then that would change or conflict with all the settings already established .....192.168 xxxx

 

Getting closer 

 

Thanks again Joe

Well....That didn't work. After selecting the DHCP and NAT with the default settings of 10.1.2 to 10 and updating I now have a "Double Nat error"

Well SomeJoe, Kept getting invalid DHCP ranges no matter what I did trying to get the NAT and the Guest Network to function. Couldn't even get back into the 2Wire configuration page at 192.178.1.254 and amber lights all over the place. figured I would start oover from scratch.  Powered everything down even disconnected the power.  Started back up ..still no connections.  I started at the begining of your instructions #2 since my router was originally set in Bridge Mode.

 

Changed the Internet "Connection Using" and set that at DHCP as opposed to Static.

Set the "Network Tab Router Mode" to DHCP and Nat (which I was having trouble with)

Updated .....and waited with fingers crossed.

 

Everything started and with all green lights and connections BUT all the IP addresses and DHCP ranges changed also.

Here's what it is now..but functioning...different but functioning.

 

Internet

Connect Using DHCP

IP Address: 108.226.96.199 (of my router)

Router Address: 108.226.96.1  (2Wire)

Primary DNS Server 192.168.1.254 (same as the 2Wire IP before but was also listed as the DNS)

 

Network

Router Mode: DHCP and NAT

DHCP Range 10.0.1.2 to 200

Guest DHCP Range: 172.16.42.2 to 200

Nat Port Maping Protocol Enabled

 

Is there anything odd or dangerous in all the IP addresses and assignments changing?  what happened to all the 192.168.25X assignments?

 

Anyway, all is functioning correctly (I think) and my router is routing and wireless working.  As long as there is no gaping holes that I'm not aware of then maybe just leave alone or is a complete 2Wire Factory Re-Set in order?  If I mess up the U-

Verse TV stuff the House Captn will be on me like white on rice :smileyhappy:......LOL

 

Thanks much for the help SomeJoe.  This stuff never goes easy for me but that is how I learn a few things along the way.

 

Bill

Dose this work with my Linksys E3200 because my MB has a gigabit port and I want to use the extra speed I think I did everything here but it seems like my net gets kinda slow at times some of the options bellow wasn't in my setup for my router like in the fire wall section their wasn't any thing to allow the DHCP renewal packets all I have is IP6 IP4 inable or disable and some filters for pinging and java but nothing to allow the DHCP packets

 

1. Set your router's WAN interface to get an IP address via DHCP.  This is required at first so that the 2Wire recognizes your router.

2. Plug your router's WAN interface to one of the 2Wire's LAN interfaces.

bgoodz,

Those settings look correct. The 192.168.1.x addresses will be used only for any devices that connect to the RG directly, like TV set-top-boxes.

Your computers will get addresses in the 10.0.1.x range, and your wireless guests will get IP addresses in the 172.16.42.x range.

TheNerd,

Yes, this will work with the Linksys E3200. Even though your computer has Gigabit, that will not increase your Internet speeds. Internet speeds are limited by what Internet speed package you've purchased, as well as network conditions.

Run some speed tests at www.speedtest.net to see what you're getting.

Good to hear that and thanks much for all your assistance and technical knowledge, It is much appreciated.

And that explains that I wasn't getting it right the first go around as the DHCP ranges for my network were reporting in the 192.168 range and sheds some light on why the system was trying to default to the 10.0.1 range.  I think the mess and confusion stated because I had the 2wire up and running and was the boss and my router was in bridge.  Then I put the 2wire in bridge (so to speak) and took my off of bridge mode.  I remember the IP assigned to my router by the 2wire initially was 192.168.1.27x and I was off to the races......

 

Sall good now, functioning and stable.

Okay, I just got U-Verse yesterday and I read how to setup my router behind the RG. I have a very customized network and I run a server and that's why I want to use my wireless router. My router is a Linksys e2500 and I set it to DHCP. I put it into DMZ+ on the RG (a i38HG) and ti works great..... for a few hours. After a few hours I can only connect to the internet or RG if I plug my computer into the RG. The rotuter seems to not get a new address for the RG and I have to reboot the router in order to reconnect. How do I fix this? The RG is setup on 10.0.0.1 and the rotuer is 192.168.0.1

Is there a particular reason why you setup your RG to use the 10.x Class A address space?

I highly doubt that you will be using a lot of IP addresses. Especially since your router is running DHCP. What I did on my RG is leave it at defaults for the 192 address and change my own router to be 192.168.2.1.

So since you have yours setup as 192.168.0.1, i would think that should work just fine. Then try setting your RG back the default 192.168.1.254 address and see if that helps out for some reason.

It may seem like to you that is non-trivial but in the latest .50 firmware update that is rollout out they are taking away the ability to setup DHCP to use the 10.x address space for the RG citing some issues.

When I was having the issues I had the RG set to the 192.168.1 subnet but I changed it to 10.0.0 because I thought it may help. That was this afternoon so I'll see if it's still acting up.

Will you want to change it off of the 10.x address space because once you receive the firmware update for your RG, if you have the 10.x address space it will reset all your settings.

However, if you have the 192 address it won't reset the settings on your RG.

I'm losing my mind with this issue. Perhaps someone of intellect can save me.....

I have my network configured as describe in the original post.

 

Here is a synopsis of the issue:

 

I am doing video conference calls to a client in Alaska via browser based software Vidyodesktop.

 

I have a network of PCs connected DHCP to a Linksys (Cisco) RV016 (IP 10.10.1.1)

 

The RV016 sits behind an AT&T U-Verse Modem (3800HGV-B).

 

The RV016 is set up on the 3800HGV-B as a DMZ passthrough device that allows all traffic to and from the router. The router does the IP assignments to the clients and the firewall work.

 

The RV016 WAN address is the Public IP assigned to the ATT Modem. I configured this as Static to match the settings in the 3800HGV-B

 

The 3800HGV-B Private IP is 192.168.1.254

 

I can establish a Video conference call from any client. After about 10-15 minutes, the session is dropped. Once the drop occurs, I continue to have full internet access EXCEPT I cannot reconnect to the Video Conference server. Pinging the both URL and the server IP yields :

Pinging connect.cvtc.org [209.161.168.13] with 32 bytes

Reply from 10.10.1.1: Destination Net Unreachable.

Reply from 10.10.1.1: Destination Net Unreachable.

Reply from 10.10.1.1: Destination Net Unreachable.

Reply from 10.10.1.1: Destination Net Unreachable.

 

Ping statistics for 209.161.168.13:

                Packets: Sent = 4. Received = 4 Lost = 0 (0% Loss).

 

Other PCs on the network CAN ping that address. The web utility in the RV016 can ping the address and the web utility in the ATT Modem can ping the address.

 

However, the affected client cannot connect (or ping) to that address for about 5 minutes, after which it can reconnect.

 

This all suggests to me these is something that remains “locked” between the client and the router, but only for that URL….

 

Going to task manager and terminating the Vidyodesktop.exe process does not “free” the connection, neither does restarting the vidyodesktop.exe process.

 

This same situation occurs when I tried all of the following:

--completely turning off the RV016 firewall

--Completely turning off Norton Internet Firewall & Antivirus

--Changing DNS servers to google & openDNS

 

IDEAS? I'm out of them!

Seems like an application issue with the video software to me. The Cisco router, the 2Wire, and the other computers on the network can still access the server IP, so the network is operating properly.

I would contact the video software manufacturer for technical support.

Thanks Joe. Let me ask you this. I configured my router WAN IP as static jest before typing the note above. Since it has been static, I have not had any issues dropping the video call on several occasions now with sessions lasting 1-3 hours in duration. Is it possible that that 10 minute DHCP renewal packet sent by the RG to the router was the culprit? I don't understand enough about networks to get how that would cause my bizarre issue. Just a sanity check...

Yes, that is conceivable. The 2Wire routers have bugs in their DHCP implementation, and many routers are affected by this problem.

The bug is that the 2Wire sends a DHCP renewal packet from the incorrect IP address. Many routers are strict about their DHCP renewal, so they ignore the renewal packet. Then the DHCP lease times out, the router shuts down it's interface (dropping all open connections), and begins a fresh DHCP negotiation. t then succeeds and brings the interface back up, but existing sessions are gone.

The work-around is to statically assign the IP address to the router, or configure the router's firewall to allow inbound DHCP renewal packets from any IP address.

Thanks. That's good to know. Everything seems good since I went the staic IP route. I wonder how long AT&T will keep my WAN IP assigned to me? From my googling it is inclear how often or even if AT&T changes the IP.

Is this the only way?  I have the 2wire modem on the outside of the house leading to a dlink switch/hub then to a 2wire router.  I want to stream video to my ipad over ftp using a Cisco linksys e4200v2 and an attached usb hard drive connected to the Cisco router.  Will setting the Cisco router behind the 2wire router cause a slowdown or lack of bandwith?  Can I get rid of the 2wire router and just use the Cisco e4200?

 

Thanks

New patient needs help -

 

Own a Netgear N300 Modem/Router.  Want to place behind the 3600 Gateway.  My reasons are two-fold.  Want to use the "N" speed of my Netgear and want to establish parental control blocks on websites. 

 

I followed Post #13.  My problem is I don't know what to change in step 3 when I'm supposed to change to the LAN IP address.  I know my 2Wire router uses the 192.168.254.1 ip address to access the router settings.  I also was able to turn off DHCP in my settings on the Netgear.  But where do I change the IP address in the Netgear.  Specifically, what screen am I looking for?  Also, do I change anything in the Netgear like the option which asks "does your ISP require you to login", or how about the option which allows you to give the Netgear a pre-determined MAC address rather than having one assigned?  I'm not trying to make this difficult, but I'm kind of new to some of these functions.  Finally, I assume I'll be able to use the parental controls of my Netgear to limit certain website usage.

 

Thanks!

If you want your router to handle parental controls, you must do full routing, not just wireless access point.

 

Follow the directions in post #2, not post #13.

With respect to post #2, this might be a really dumb question, but how do I connect a WAN to a LAN interface. Isn't the WAN the Internet port on the back of my Netgear which is basically a standard phone jack plug, but the LAN is an ethernet type connection.

The WAN interface on the NetGear should also be an Ethernet connection. It is designed to connect (via Ethernet) to a cable or DSL modem's network port.

But my Netgear N300 is a modem/router.  How does that change my set-up?  It has four ethernet ports and one WAN port for a phoneline type connection from my DSL line.

Your steps look good.  I tried to configure follow them to configure the 2wire 3600hgv as a modem/gateway, and keep using my Linksys 3000 as the wireless router.  After completing the first few steps (setting the Linksys with DHCP, connecting its WAN port to the 2Wire's LAN port ...), I logged onto the 2Wire's setup page but couldn't see the Linksys router (I restarted the Linksys also).  Did I miss something?

But my Netgear N300 is a modem/router.  How does that change my set-up?  It has four ethernet ports and one WAN port for a phoneline type connection from my DSL line.


 

I cannot look up the exact router you're using, because "N300" is not the model number.  This is just a moniker that NetGear uses to describe any of it's routers that have 802.11n wireless.

 

However, I found one, model number DGND3300v2, that sounds like what you're using.  This is an ADSL2+ modem and router all in one.

 

This device will not work the way you want it with U-Verse.  You cannot replace the 2Wire 3600 gateway with your Netgear, AT&T's network will not allow it.  If you want to use parental controls on a router, you will need to purchase a standard DSL/Cable router that has the parental controls features, and hook it up in accordance with post #2.

 

Find an appropriate router using this comparison chart from NetGear:

Your steps look good.  I tried to configure follow them to configure the 2wire 3600hgv as a modem/gateway, and keep using my Linksys 3000 as the wireless router.  After completing the first few steps (setting the Linksys with DHCP, connecting its WAN port to the 2Wire's LAN port ...), I logged onto the 2Wire's setup page but couldn't see the Linksys router (I restarted the Linksys also).  Did I miss something?


 

If you run into this issue, log into the Linksys and use the network tools.  Have the Linksys ping the 2Wire router.  Once that is done, check the 2Wire's device list and the Linksys should then be listed.

 

If that doesn't work, try the same thing from the other direction: Log into the 2Wire, use the network tools (under the diagnostics menu) and ping the Linksys.

Thank you for all of your help in this thread SomeJoe.  I have used your instructions in post 13 to set up my linksys e4200 as a wireless access point and switch.  Here is my set up.  I have the i38hg connected to the iNid by twisted pair in a bedroom on the second floor of my home.  I have the e4200 on the main floor connected to the iNid with cat6 lan to lan.  I set the ip address to 192.168.1.10 for the e4200 and turned off dhcp.  I changed the e4200 ssid and network key to that of the 2Wire except for the 5ghz band.  I have a tv and ps3 hardwired to the e4200.

 

Everything works great for a few hours and then the e4200 drops all connections and the light on it slowly flashes.  Once I power it off and then on it works again.  What am I doing wrong?

That sounds like the 4200 is having some sort of internal problem. When it does this, the light that is flashing may flash in a pattern of some sort. You might want to look up in the operator's guide what the flashing light means, it might tell you what's going on.

If that doesn't work, you might temporarily try a different router configured the same way and see what happens.
