Tom, Setting up connection sharing is very easy in Windows. Just look at the help topic internet connection sharing which should take you through it. I haven't used it since an early version of Windows 2000. Generally windows will set up the gateway machine on 192.168.0.1 and the gateway will function as a dhcp server for the network.
I know XP now incorporates some sort of firewall which you can activate, but I believe it is fairly basic. I don't know how or whether you can do port-forwarding. I agree that a firewall router type appliance would be preferable. Alternately, if you have an old unused machine around smoothwall or mitel server (formerly e-smith) and similar solutions also do a good job. However, I bear in mind the possibility that your friend will not be keen on reconfiguring his whole network. regards, Darryl -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
