So I'm looking to beef up my home network a bit - do you folks have any recommendations on solid multifunction devices that can do firewall/VPN/IDS/IPS/AV for a home network?
I'm not looking to spend a lot of cash, and I'm more inclined to get a device that I can set up once and never bother with again.
I currently have Comcast (boo) and a Linksys WRT610N set up on my home network. Looking through my old devices that are collecting dust, I have a US Robotics Secure Storage Router Pro VPN/Firewall/NAS Model USR8200 (hey, I forgot I had that - last firmware update was 2006), as well as a Linksys 4 Port Gigabit Security Router with VPN Model RVS4000 (also ancient). Heh, man, I remember when I had all those devices in one network, all groovin... until I got married and had to cut down on the device count. And laptops too.

Ideally in a perfect world I would have: Internet from Comcast > Firewall (multifunction security device) > Router > Wireless (guest)/Wireless (home)/Wireless (lab). Guest, Home, and Lab wireless networks would not be able to get to each other, and I would be able to do any particular routing and VLAN segregation that I would need to.
I also want to be able to connect to my home network securely through something like OpenVPN. Also, I need to figure out a way to use something like dynamic DNS to make sure that I can access my network even though the IP changes...
Thoughts?
