How to set 2-wire into bridge mode?

Hi everyone!

I have a 2-wire 3800HGV-B wireless router from AT&T that I need to set into bridging mode not DMZ.  I have a DD-WRT router that I just installed on my home network, and I also have a small server.  Before the DD-WRT router, I had the server on DMZ on the 2-wire, and after I setup the DD-WRT router, it made me put that into DMZ mode.  I tried connecting the server to the DD-WRT and putting that on the DD-WRT DMZ mode, but that doesn't work.  I've tried using port forwarding on both my 2-wire and DD-WRT routers to send specific ports to the server on a private IP address, but that isn't working either.  The best solution I can come up with is to put the 2-wire into bridging, and a friend of mine did it with another 2-wire router (not the same model... he tried to help me out and wasn't able to do it), so I think it's possible, but I've tried to do it with no luck.

I have tried Google, but everything that comes up that claims to be bridging is just setting the router to DMZ.

Any help or other suggestions would be appreciated!  Thanks!

I've never had any luck with 2-wire branded network products. They are designed for ABSOLUTE useless end home users (per the isp) so they are very non-configurable. I know it doesn't answer your question, but I can attest changing anything on them is awful.

Ya... that's why I want it to act as just my modem and not my router!  ;)

I think I might have figured out a way to map certain ports to certain private IP addresses through an advanced port forwarding, and by having two different IP addresses on my server... but using DMZ on my DD-WRT router would definitely be nice. Thanks anyway! :)
I had to fight with my ISP to get them to give me a 'just modem' instead of the crap 2wire gateway they sent me. I ended up having to BUY the modem but at least I didn't have to deal with their inferior hardware.

Wow... And I happen to know that in my area, many people pay extra so that they can get "wireless". That's too bad that you had to pay to get just a modem, many people in my area would love to trade places with you! ;)
the one they offered me didn't have port forwarding, only dmz -- not so good for ps3 gaming that needs open ports; given that the dmz didn't even work :S

Wow... I guess I shouldn't be surprised; after all, 2-wire is awful! ;)

It's possible to disable the routing features of the 2wire and just set it to a bridge. Go to http://gateway/mdc - you can replace gateway with the ip address of the router. You will need the mdc password (different from the admin password) - try 2wire. In the mdc settings, you should be able to find a setting entitled "enable routing", just uncheck that box and your router is in bridge mode.

Separately, you might want to disable the wireless as well - that can be accessed from the normal interface, just uncheck the wireless box. Not the greatest router, but I'm guessing it was free.
