I'm strongly considering getting an Airport Extreme as a Christmas present to myself. But I have a few questions about it which I can't really find online. Firstly, our setup here goes like this: We have a Fiber connection that comes out of its own little modem mounted in the wall. From there a regular Ethernet cable goes to a a router issued by our ISP. Only reason we uses this router is because we have voip landline phone service via our ISP. Although there's just an adapter you connect your landline phone to and then a regular Ethernet cable connects to a designated phone port on the router I assume there's special software on that router handling the phone services. So I guess the Extreme can't handle that? Based on that guess I'm planning to bridge the ISP router with the Extreme. Or does anyone have a better suggestion? There's a few things I would like to do with the Extreme. Firstly, I want to use the Guest network capabilities. I'd like to set this Guest network to use a small part of the total bandwidth. Is it possible to regulate that via the Airport Utility? Also I would like to block certain domains or Bittorrent in general on the Guest network? Can you do this on the Airport Extreme? Thanks for any help!
