So go ahead and try it! Use a differnet subnet (in my earlier example, try a pool in 192.168.3.0), and try connecting (from outside the firewall, of course - a dialup connection would work for testing).

See what IP you get assigned on your remote computer. Then try to connect to a machine over a port you know (a web connection, some sort of terminal/vnc, etc), and do a netstat /a type of command to see what IP is connecting to the inside computer.

Someone who obsesses over obscure registry entries to change miniscule windows settings should be able to poke at a firewall. Just save your existing firewall configuration so you can restore it when^h^h^h^h if you mess it up.
