This forum is for Windows Firewall Discussion. You may wish to post this to
microsoft.public.win2000.networking.

And to try to be of help, you may want to sniff on the Linux servers, see
if they are even getting the packets from the VPN client. Your entire setup
is not clear, and you may be experiencing a simple route issue ( if the
Linux boxes don't know where to send packets to the VPN client's subnet
etc. ) A sniff of a simple PING should help you determine where to look.
Post back in the appropriate forum and I'll try to help more.
