Today I am giving AT&T U-verse a go to see if it will be better than my current service provider. The general install went fine, but there are new intricacies that wreaked a bit of havoc on my network setup.
Before, I had a basic cable modem and connected my Time Capsule to the cable modem and everything was run from the Time Capsule. Pretty basic.
But with U-verse, they provide you what they call a residential gateway which basically is the hub for your internet and tv data (I think). It is a 2Wire 3801HGV. On the internet side, this hub serves as a both a wireless router and modem. It has NAT, dishes out IP addresses, allows wireless clients, etc. But, I wanted my Time Capsule to be the wireless hub since I use it for backup, etc.
So when the install was done, and I tried to connect the Time Capsule to the 2Wire, the Time Capsule blinked yellow. After some research, I realized this was probably due to the 2wire and Time Capsule fighting over dishing out IP addresses, but I am not 100% sure that is the case.
Anyway, to get around this issue, I turned off the wireless connectivity on the 2Wire, changed the Time Capsule to Bridge Mode instead of the current setting of "Share a Public IP address". I then connected an ethernet cable from a port in the 2Wire to the WAN connection on the Time Capsule, and everything seems to work ok connection wise. The Time Capsule light is green, and I can connect wirelessly from my computers at home.
However, I lose functionality. My Guest Network capability from the Time Capsule is gone. I don't think Back To My Mac is operational.
Is this the way you would have set things up? Is this loss of functionality expected? Anyway around this loss of functionality. I read, but did not quite understand, some people talking about DMZs and bypassing the routing on the 2Wire. Would that be better? Also, as a bonus, would you connect other direct-connect devices (Ooma, for example) to the 2Wire or to the Time Capsule?
