So, I'm finally getting around to getting my home network built the way I want it and I'm discovering the considerable lack of functionality on the 3801 that I can only assume is a feature of AT&T hobbling the firmware. There is no ability to add static routes and you can't disable DHCP. This is kind of crappy and limiting. I need more private subnets behind another router and would prefer to run my own more capable DHCP server.
I also noticed that the Multicast video traffic floods all ports on the 3801, regardless of IGMP membership.
I wanted to have one port extended to a VLAN on my switch to support my set top boxes on an isolated segment with IGMP snooping turned on. A second port would connect to an outside interface on my router that I would use to segment my wired LAN, Wireless APs and VoIP traffic and deliver all the security capabilities I want to deploy.
Any possibility that AT&T might open this functionality back up on these boxes or make it available on the new Motorola boxes that are coming?
Without static routing I have to enable NAT on my downstream router which sucks. Then I have to double NAT my traffic to get to the Internet. Bleh! It would be real nice to support bridging on the gateway and allow the public IP to live on a customer's equipment if they wanted to.
Is there any way a customer can actually build a real network behind a UVerse connection without being forced into the pre-packaged walled garden these gateways put you in?--
