Hi all!

It seems I have to have an Windows XP box inside the firewall for some 
time to come... :-( (It's not my network, it's my parent's, and they 
have a laptop with XP, their workstation is allready on Woody). 

What I'm worried about is that someone may get into the XP box (by 
sending a trojan by e-mail for example), and so have something on the 
inside they can use to take down the rest of the network. It would be a 
lot more serious if they got to the workstation or the router/firewall  
itself, because they are almost always on. My parents know that they 
shouldn't have anything of value on the laptop as long as it running 
XP. 

The question is really if I could do something in the firewall that 
would help isolate the XP box somewhat. Closing outgoing ports (input 
ports are all closed), drop certain types of packages, or something 
like that? 

Any ideas? 

Cheers,

Kjetil
