Diagram of FiOS Network

I thought it might be helpful for those considering Verizon FiOS to know what the topology might look like. The diagram shows my current topology.

Two things I am curious about.
1. The STBs show up in the router as Coax IP connections.
2. The internet connection comes into the router through the coax same splitter that connects the STBs.
3. The home media option allows me to access music and photos from my primary workstation.

I suspect that this allows the STB to get OnDemand via IP without going through the router. However, it also means that for the Home Media option to work the STBs have to be punched through the firewall in the router since they are technically connected to the WAN port.

It is also possible that the STBs have wireless capabilities that may get them "inside" the firewall. If this is the case then what happens if I try and change from WEP to WPA? WEP is configured by default and the "key" is etched on the bottom of the Router. I definately plan on moving to WPA so I'll learn pretty quick if the STBs are wireless or coax?

Also the HD DVR STB has an ethernet jack on the back however the installer told me that it wasn't necessary to use.

I will post some screen shots of the router. It has a very polished and slick GUI that I like quite a bit. However, I do want to do some port scans and traffic analysis on both my internal network and from the internet to see how the data is flowing.
