So I'm looking for suggestions for a good home network firewall/router/proxy device. What I really need/want is good filtering rules so that I can filter IP/port combinations, port ranges, devices, protocols, pretty much as much filtering control as I can get, as well as the standard NAT and in bound port forwarding options. A reasonable amount of URL filtering would be good as well. Caching is not a requirement. The proxy must allow for filtering as well.
I have a 13 year old daughter who absolutely loves her Google Voice account, which her dad made the mistake of getting her. There was actually good intent behind it as I will not get her a mobile phone right now as she has no need, but the ability to text family and friends is useful and she has an Android tablet. Not really worried about her going places on the web that she shouldn't, she just can't seem to stop texting and chatting when she is supposed to be doing other stuff, like homework.
So, the ability to block Google Voice and Google Talk traffic without blocking gmail or google search is a good example. I need to be able to block both the web interface and app traffic for both. These are the current examples, but I'm sure I can come up with others.
So, suggestions for a device? I'm willing to pay a fairly significant amount for a good device, especially if it supports a good DHCP server and VPN as well. I know I can do it with a Linux box, but honestly I spend enough time doing that kind of stuff for my day job. I'm happy to pay the money to save my time, assuming the appliance I buy has a reasonable interface and features.
Thanks for the suggestions.

PS: 19" rack mount form factor is a good bonus.
