It depends. Are you setting the default gateway in the DHCP lease so the win7
box knows to forward to you? What is the default gateway on the FBSD box? How
is the win7 resolving hostnames? Can you ping the em0 address from the win7 box?
Is the em0 address a public or private address? If private, how are you going to
route from the cable modem back to your WiFi subnet?
This is all needed to determine why the win7 box cannot reach the internet.
