XP? With 8G memory? :P

I'd use 64bit W7 instead if going Virtualbox route. Even with extra
memory use you should still be able to use 5GB or so for guests.

I'd simply use the right tools for the right job. You needed Windows
gaming, and AFAIK "real" Windows is the only clean, stable, supported
way to get it.

Yes, which is why I suggested use native Windows and use virtualbox
for Linux and other guests.

It's optional really. Basically if you limit incoming traffic to
Windows you'll have less vulnerable to remote attacks. Of course it
could work just fine even without it.

Another option to network setup is using bridge with dummy address.
IIRC you could have a bridge with TAP32 (virtual) adapters and real
NICs, and setup virtualbox to bridge on that interface. On
public-facing interface, use static dummy IP address on Windows side,
and use real public IP address on Linux guest. Setup the linux guest
to act as firewall/NAT for windows (and other hosts that needs it).
