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)

I put the powerline adapters back in play. They are the 200mbps jobbers. The throughput isn't great (on the best outlet combo I've found I get 3.75MB/sec) but seems to be good enough for HD playback. It also seems like sometimes I need to unplug them and plug them back in which is fairly annoying but maybe its just the price I have to pay and they will 'settle down' once I ahve everything going.
This weekend I plan to revert my setup back to RG -> DD-WRT -> pfsense. Think I may have overreacted when I swapped everything back last Sunday night after streaming was crawling.
That being said, I will need to replace one of the switches so I am going to look for a 16port one that supports VLans

Thanks for the quick reply.
Followed post #2; since the LInksys e4200 router was preprogrammed with IP address of 192.168.1.1, I had to change the RG IP address. Once I got them of the same network it worked. Partially. I am able to access the internet on all my devices connect via wired or wireless to the router (or the gateway for that matter).
Issue I've noticed is the following: all of the devices in my house, which I was able to connect to previously, are no longer accessible. For example, I have 2 dlink cameras, media server, receiver, blu ray, all with fixed ip addresses that were previously accessible via port forwarding through the router. The cameras are live in the sense that the light on the front indicates that they are on the wireless network (home network, SSID name, not the 2Wire network). However, when I interrogate the router for all connected devices, none of them show. I have powered them on and off and have refreshed the router. What is most interesting is that if I type in the external ip address to the RG (I have verified by ipconfig that it is the external address my router has as well) xx.xxx.x.x: port number to the camera, I can access the cameras. Yet, while connected on my intranet if I type 192.168.1.1: port number, I am unable to access the camera. If I enter 192.168.1.x for the particular camera, I am unable to connect. This problem is further compounded by the fact that mydlink.com which was typically able to access the cameras is unable to do so.
As an aside, I have also verified that mydomainname.com (via tzo dns server) has the correct ip address - i.e. the router is able to connect with tzo.
Next question relates to using the HD boxes from Uverse to access my server. I assume to get from the gateway to the server I need to point to the external domain name first. Correct?

Got it. I didn't quite get the difference in subnet. The RG is handing the external IP without difficulty. I can reset the RG back to 192.168.1.254 and then change the linksys to the 192.168.2.1. I was hoping to avoid having to change the IP addresses of all of the devices in the house, but understand that I have to do it.
Thanks for the great advice.

Not sure I have time to address this tonight.
But, last night I changed the RG ip address via the settings-> LAN->DHCP to the 172.16.0.0/255.255.0.0 selection. This changed my RG ip address to 172.16.0.1. I then put the router back to the settings that worked for me - ip address 192.168.1.1 and was able to access the web and external IP handoff worked seamlessly. However, with this setup I was unable access the other devices that were connected to the router - which for some reason were not visible (see my previous post). Any explanation for that? All devices have an ip address 192.168.1.x and are connected wirelessly to the router.
Thanks for the education!

Thanks much. Will give it a try. I hadn't rebooted the RG - probably need to do that.
When I wrote the other night, I had the RG IP set to the 172.16.0.0/16 and the Linksys to 192.168.1.1 (external ip was passed seamlessly to the linksys). Unfortunately, as mentioned, I was unable to access all the devices (cameras, server, etc) even though they had been re-booted as well and even though they indicated connected and I was able to connect via port forwarding through the external IP.
I think hoping to have everything work the way it was wishing for too much. Will likely have to reset everything and start over.
HOpefully will have positive news tonight.

Set RG IP to 172.16.0.0/16. IP of RG set to 172.16.0.1. Couldn't reboot RG as wife was watching tv.
However, the external IP was 108.xxx.xx.xx.
Set the Linksys back to 192.168.1.1 and rebooted.
External IP was passed successfully to Linksys and was able to connect to internet. Success!
2 dlink cameras with fixed IP addresses (before switching from Comcast) show green led indicating they are connected to my wireless router. However, the router does not show they are connected.
I cannot get to the cameras via 192.168.1.11 or .12 (their assigned IP addresses) even after re-booting both cameras.
I cannot get to the cameras via 192.168.1.1:81 or :82 (their assigned ports via port fowarding). This all worked previously.
However, I CAN get to the cameras via external IP:81 or <mydomainname.com>:81 or :82.
Fascinating and frustrating. Any ideas? Would UPnP (active) have anything to do with this?

I should have clarified. The cameras are wireless IP cameras. I can ping them successfully.
I cannot access them via their local IP address or via port forwarding through the router (e.g. 192.168.1.1:81).
I can get to them via <external IP>:81
Mydlink.com which establishes a link with the cameras says the cameras are offline. I had trouble establishing this in the past due to having a server on the network that I wanted to be able to access via port 80).
Let me outline the entire network:
RG -> LInksys e4200 -> home wireless network (ipads, phones, wireless ip cameras)
-> Linksys e4200 -> switch -> wired imac, readynas server, receiver, blu ray
The cameras and the server have dedicated, fixed IP while the receiver and blu ray are assigned via dhcp (by the router).
I'm not even bothering yet with the receiver, blu ray and server until I can prove I can get the wireless ip cameras to work.
Thanks very much for all of your help!
