| Router behind 2wire Hi all,
I tried a quick search but couldn't seem to find anything. I am thinking of ordering a Cisco/Linksys EA6500 wireless router to play around and do some testing with. In my current home setup, I have the following:
3801HGV - Currently also using the built in WiFi
Cisco IPN4320 Receiver - Connected to 3801 via ethernet
Cisco ISB7005 Receiver - Connected to VEN401 WAP
Cisco VEN401 (I think) WAP - Connected to 3801 via ethernet
I was wondering if it is possible to place the 3801 in bridge mode and use it simply as a modem. Can I have the devices currently plugged into the 3801 plugged into the router instead? I'd like to use the firewall, DHCP, NAT...everything on the new router instead of the 3801.
Is this possible?

| Yes, it is possible though it's not a true bridge mode. Unfortunately, I can't find the link to the forum post that explains how to do it. Basically, you need to put your new router into the 2Wire's DMZ+ mode in the settings accessible from the web interface. I think you hook the new router's WAN port up to a LAN port on the 2Wire and then you can assign that LAN port as being in the DMZ+ zone. There some other steps that I'm blanking on though 
PS That's an awesome sig |

The 4320 & VEN401 both need to stay connected directly to the 3801 via Ethernet
But you can connect a 3rd party router behind the 3801 and configure it for all regular internet-using devices
There is no true bridge mode, but DMZ+ is pretty close, passing the public IP to the secondary router, and in theory opening all the available ports
It would probably also be a good idea to disable the 3801's WiFi radio if you intend to use a 3rd party router for WiFi access |

Had intended on disabling the radio, I'd like to use the b/g/n/ac features on the new router.
I've found some documentation online that shows how to place the 3801 into true bridge mode. It shows disabling routing mode, NAT, DHCP...everything.
If DHCP and NAT are disabled on the 3801, and my router is handing an address and doing translation for the 4320 and VEN401, why wouldn't they be able to hang off the router? That is assuming that the built in switch supports IGMP snooping and the like, which I'm pretty sure it does. It's just data, like any other device on the network.

kudos:1 | IGMP snooping is usually LAN side... I have yet to see a consumer grade router do it through the WAN correctly if at all that wasn't specially designed for it..
The easiest way to do it is as ILpt4U  says |

There may be documentation available on how to disable DHCP and NAT and use true bridge mode on the 3801, but the AT&T U-Verse firmware disables those options
Best bet is to leave the 4320 and VEN401 connected ethernet to the 3801 directly |
