VNC via dial-up networking ?

Mark,

It sounds like the PC you are trying to connect from does not have
an appropriate IP route to the dialed-in machine. Try one of the
following:

1) On the PC where you want to run the viewer, set the RAS server
as the default gateway in "Network Nbrhood->Properties->Protocols->
TCP/IP->Properties" (That's NT4, may be a bit different for Win9x
or 2K). Of course, this may interfere with your PC's ability to
access other network resources.

2) At the command line of the machine where you want to run the viewer:

route add <IP-of-dialed-in-PC> <IP-of-RAS-server> MASK <appropriate
netmask>

The netmask should be the same as that of the dialed-in PC, which
you should be able to find out by doing a "netstat -r" at the
RAS server (I think). This should fix your problem without
causing any undesirable side effects. Windows' "route" command is
a little odd, so I may not have the syntax exactly right; you
may need to experiment a bit.

HTH,
