Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have a situation where AT&T seems to be very uncooperative in their selection of modems (routers) for their business class DSL service. They essentially gave us only two options for modems (which are simply routers) for their service. It seems as though a wide variety of other solutions would work just fine, such as even a DD-WRT flashed device.

It is obvious that they will not support an installation with such a router, however they gave us the impression of doing something like this as being against their terms of service (although they did not explicitly say this; they were more vague saying that they only support X and Y devices that they sell).

The modems (routers) that they sell and support are trash. They do not facilitate any serious port forwarding (I am running SIP video solutions across this connection) and it has become a situation where if I cannot replace their routers, we're going to have to try to find a more flexible ISP (although few, if any, options exist it seems).

Does anyone have any experience working with more robust server infrastructure behind an AT&T ISP connection who has set up their own router solution and can vouch for their "allowing" such a configuration?

Typically you will need some kind of managed services arrangement with an ISP for them to allow you to use more a more reasonable modem.

I'd recommend, if you are doing anything on the connection that you care about, that you minimize the presence of all-in-one style devices like the very residential-gateway-like devices usually provisioned, or like a router+wap+modem+switch+firewall running dd-wrt.

On a budget, I usually find that requesting a modem-only device (sometimes they will put their modem combo device in "bridge" mode to accomplish this), and then using a linux or BSD box with two NICs to facilitate the routing is effective. If you can afford it, put a real router up.
