You have to enable tcp/ip networking in Windows...somewhere under
control panel I think, and you have to give ppp the -nat option on
your BSD box. If you've done that then your problem is possibly name
resolution on your Windows machine.

Fire up your connection & then:

C:> ping
C:> ping
C:> ping


C:> tracert

from one of your Windows machines & post the output.

Also do:

$ netstat -r

on your gateway & post that to. Then we've got a bit to go on.
