You should be able to use "routed -s", since it *is* a gateway box.

Routing seems to be working then. :)

Ping uses ICMP packets, and not TCP/IP packets.

Try to disable TCP Extensions and see if that helps.  (in
/etc/sysconfig, set it to NO and reboot).  I *doubt* it would help, but
stranger things have happened.  I'm using a similar setup here, and I
have no problems with *any* machines, although I'm using SCO and Sun
boxes.

Also, if you've got flow control problems at either the home end or on
the server you will also see problems, but then it shouldn't matter
which host you connect to either.
