Connecting to other Tivos on my network

I have a wireless bridge in a room where I did not have wired internet access so the kids can play XBox Live. I plugged in my Tivo to the bridge to go out and get guide data. So far, so good.
I know the bridge is speaking to my main router. How can I get to see the other Tivos that are connected wirelessly to the main router?

Sorry for my clumsy language.
This is all really over my head. I just got lucky with hooking up the bridge.
Thanks if you can help me at all.
