Ha! The very thing unix/linux is famous for - networking!

Here is the routing table on my linux machine.=20

Kernel IP routing table

My LAN is 192.168.100.*, and 203.94.227.17 is the machine to which I connect
via ppp (MTNL).

Just set up the default gateway of the windows machines as the linux one, a=
nd
use the ip-* scripts to set up the routing table entries when the ppp link
goes up, and to delete them when it goes down.
