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'm running the 3800HGV-B with a Netgear WNDR3700v2 router and followed all the steps in post #2 and my router is not getting the public IP. It keeps getting it from the RG of 192.168.x.x and the private network is getting 10.0.0.x. I rebooted both devices one at a time and still not getting the publis IP on the Netgear.

Great post and feedback. I have read through all of your instructions however I am still a bit 'fuzzy' as to which configuration will suit me best.
I want to use my ASUS RT-N56U for everything, not just an access point. I want to turn 'wireless off' the RG and only use the RG for TV and my internet feed to my router. So to be even more clear, I want nothing connected to my RG except for the router to receive the internet from it in order to provide it to a single network both LAN and WAN on my router. Does that make sense?
This also includes firewall functions as well.
Should I follow post 2 and just disable everything on the RG i.e. wireless, lan, wan? Will I still have to have 2 subnets in order for this to work properly?
Your feedback is invaulable. Thank you.

There are some routers that have issues with the DHCP renewal process from the 2Wire router. To correct this, open a firewall port on your D-Link to accept all inbound traffic from any IP address on UDP port 68.
It appears that I've got one of these routers. Outlook on any computer connected to the LAN is loosing connection to Exchange Server every 10 minutes, resulting in Outlook freezing for several seconds while the connection is being restored. This never happped with just the 2Wire router.
I've followed the instructions in post #2 to set up my router behind the 2Wire. I set up the port forwarding on my router as follows:
Port Forward settings:
Port from = 68
Port to = 68
Protocol = UDP
IP Address forwarded to = static LAN address (for me 192.168.1.1)
Is this the right way to set this up? It doesn't change the Outlook problems I'm having.
Thanks so much for your help with this!

The router is a Linksys WRT54GL with DD-WRT v24-sp2 installed.
It did let me enter the WAN address, and I changed the "from" to 67, and the "to" remains 68.
But that didn't change the Outlook behavior, unfortunately. Still disconnecting every 10 minutes.

Yep, post #13 should do nicely for you. Plug your NAS into one of the LAN ports on your router.
In general, the only reasons you might need to use post #2 instead of post #13:
• You want to control ports on your firewall using your router rather than the 2Wire.
• You have a device or application that needs UPnP (like some gaming systems)
• You need parental controls, QOS, or VPN functions that only your router can do.
If all you want is more reliable wireless, or 802.11n (faster) wireless, you don't need post #2, you only need post #13.
