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

[ Edited ]

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?

After my spam of replies I have fixed my problem.  I had to set the router to static and type in the gateway, dns servers, etc that is listed on the uverse box.  Port forwarding works fine now on the linksys.  Yay!

I just wanted to tack on a 'thank you' to SomeJoe7777. I was getting absolute crap internet speeds upstairs on my PC with the default wireless connection. I used the guide to setup my 802.11n router, and now it's running near-enough my advertised download speeds.

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

i recently moved from the country where the only available static IP was a very expensive T1 line.  Now in the city I had two choices, AT&T or Time Warner.  After much discussion with AT&T representatives that uVerse would provide me with the same capability to manage my block of 32 static IP addresses, I pulled the plug and moved my equipment to the new location, expecting at one or two day outage. That was a week ago.  WIth the end on the month approaching and no access to my accounting system (LegerSMB), I am running out of time.  i have poured  through the forums looking for a solution, but it has eluded me. Here is my setup.

 

I run my own, DNS (named), DHCP, sendmail MTA, bacula, ejabberd, Mailman servers, CalDav, and apache servers from behind my fire wall.  Some of the servers are physical, some are KVM hosted, some are apache virtual web hosts. The only connection to the 3801 is my linux based (centos) firewall that manages the connection to the internet. It has all of the active static IP addresses set up as eth0, eth0:1, eth0:2, etc.  The 3801 recognizes the eth0 static IP address 162.192.165.97, passing traffic both directions. 162.192.165.97:80 is correctly NAT'ed to the apache server behing the fire wall, for example. Everything from inside the firewall is working correctly with data passng to and from the internet. We can send mail internally or externally and can receive mail, from inside the firwall, for example. I am willing to change the configuration anywhere in my system, provided it does not change the presentation to the end users either on the local net or the internet. 

 

Here is the question. Can this be made to work and how,  or should I move to Time Warner Cable? I am concerned that I'd be moving from  the frying pan to the fire. I asusmed an internet company would be better prepaerd than a cable company. :-)

 

Any Help, much appreciated.

I'm a bit confused by your post. In your second paragraph, you basically describe that everything is working. What isn't working that you need assistance with?

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

Sorry, too much superfluous information, I suspect.  My problem is, except for 162.192.165.97, the internet cannot see any of my static ip addresses, including my dns servers on 162.192.165.124 and 125. So no DNS lookup is occurring. Even if that worked and pointed to my web server on 98, for example,  the 3801 does not pass the 98 traffic to my firewall. So you can go to the web server on 97 (but not by name) but cannot get to any of the other servers or services on 98 through 125 by ip or name.

 

I am hoping there is a change I can make in my firewall as a workaround or a change to the 3801.

What you're running into is a limitation of the 2Wire gateway in that it is hard coded to expect a 1-to-1 relationship between IP addresses and MAC addresses. Each static IP address you're using must appear to the 2Wire gateway to be coming from a different MAC address. I suspect that your Linux router is answering the 2Wire with the same MAC address for all IP addresses, which will not work.

If your Linux router can assign different MAC addresses to eth0:1, eth0:2, etc. then that should solve the problem.

If not, there is another potential workaround if your 2Wire gateway is running the very latest firmware (6.9.1.42). Can you log into the 2Wire and check to see what firmware version it's running?

The FW level is 6.9.1.42-enh.tm.   The eth1:X is more like an iP alias. All of the :X's share the eth1 mac address.  More over putting MACADDR=  or HWADDR in the X's is ignored and the eth1 mac address is inserted.

OK, I have not tested this because it is so new.  But you are a good candidate for the cascaded router option in the new firmware.  Follow these steps:

  1. Remove all of the eth0:X addresses from your Linux router.
  2. eth0 will be the "outside" interface of your Linux router.  You will assign it a private IP address within the same private subnet that the 2Wire 3801 uses.  By default, the 2Wire uses 192.168.1.0/24, with the 2Wire itself at 192.168.1.254.  Give your Linux router a private address in this range, but outside the DHCP range that the 2Wire is issuing.  By default, the 2Wire issues 192.168.1.64 through 192.168.1.253.  Pick an address below .64, for example 192.168.1.20.
  3. eth0 will be 192.168.1.20, subnet mask 255.255.255.0, gateway 192.168.1.254.
  4. eth1 will be the "inside" interface of your Linux router, you will assign it an address from your static range.  For example, use 162.192.165.97.  You can then assign 162.192.165.98 through 162.192.165.126 to your servers and devices.
  5. On the 2Wire router, go to Settings -> Broadband -> Link Configuration.  Uncheck the "Add Additional Network" checkbox and click the Save button.  This removes the static IP addresses from the 2Wire's LAN network.
  6. Verify you can now reach the Internet from the Linux box.
  7. Now on the 2Wire router, again go to Settings -> Broadband -> Link Configuration.  Check the "Add Cascaded Router" checkbox, and use 162.192.165.96 for the network address, 255.255.255.224 for the subnet mask, and then choose your Linux router's outside IP address (192.168.1.20) for the "router that will host the secondary subnet", and click Save.
  8. Configure your servers and other devices with the remainder of the static IP addresses.  Example: 162.192.165.98 for the IP address, 255.255.255.224 for the subnet mask, 162.192.165.97 for the default gateway.  All of these servers should be connected to the network segment that is connected to eth1 on the Linux router.

 

Those servers should now be able to reach the internet, and you can configure the firewall on the Linux router as you want.  Some other notes:

 

  • Even though the Linux router's outside IP address is a private IP, there is no NAT/masquerade going on here.  Packets are routed over the private 192.168.1.x network, but no address from your static block is ever translated.
  • Yes, I know that having a private IP on the "outside" and a public IP on the "inside" looks backwards, but this is correct routing for this setup.
  • No need to configure the firewall on the 2Wire, since it is now acting as a pure router for your static IPs.
  • Some protocols may still not work due to upstream AT&T interference.  IP protocol 41 (IPv6 in IPv4) is currently blocked by this version of the 2Wire firmware.
  • I have not tested this configuration at all (I intend to as soon as I get back from a business trip), so no guarantees.

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

Thanks, SomeJoe7777. I too am on a business trip. Since this requres taking the interface down with the potential of it not coming back up, I'll try it when I get home.  After you described the problem for me, I was able to find a potential way to get my firewall to present a different mac address for each ip by using the bridge function and taps.  If I get that to work, I'll post the solution.

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

Hello Somejoe,

 

I'm not sure if this is still an active post, but i'm trying to figure out a couple things in your config or really just wanted to double check.. what does the address 192.168.160.20 belong to? My first thought was an attach switch from your router connect to int fa0/0 on the switch.

 

I'm trying to figure out how to get my 2600 cisco router to play nice with my AT&T router. I have followed the instructions that you have provided, well the best that i can anyways..

 

my setup is like this:

Port 2 on the AT&T router is connect to the Cisco 2600 router on port fa0/1

Cisco 2600 port fa0/0 is connect to 2950 layer 2 switch on port 23

Host machine is connected to port 1 on the 2950 switch

 

this setup allows me to ping the outside world like google, yahoo etc from the my host machine but does not allow me to use an internet browser to browse to the site. it just keeps loading with no results. I believe this has something todo with my acl or routing. I was wondering if you or anyone could please take a look at my configs and suggest anything that might help..

is setup as a bridge per your instructions (DMZplus mode)

Can you verify that your f0/1 interface is getting correct DHCP information from the 2Wire? Post the output of:

show ip int f0/1

show ip route

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

Hmmm ... almost everything looks correct, but I notice you have not defined any static routes.

Do the following:

show dhcp lease

In that output, there should be a default gateway listed. Using that IP insert the following two lines:

ip route 0.0.0.0 0.0.0.0 <gateway IP address>
ip route 192.168.1.0 255.255.255.0 FastEthernet0/1

See if this makes a difference.

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

After 3 weeks of effort, with support from 3 levels of AT&T tech support as well as this forum, I have concluded that the AT&T router is incapable of supporting my environment.  I installed Time Warner Cable Business Internet last Friday and had my environment running in less than 3 hours.  (The only reason it took 3 hours, was that TWC had messed up a routing table which caused the routing to go into an infinite loop resulting in a timeout. Bottom lline, the TWC router worked just like the T1 router, passing everything down the pipe.

 

I want to thank SomeJoe for his effort in trying to get this to work. Another week of work may have yielded sucess, but I ran out of time.
