Yeah, I guessed that ports in use could not be forwarded.
I meant more along the lines of forwarding all other ports, or
specifying a range of ports rather than a rule for individual ones.

VPN is our long-term goal, using token authentication, 3DES VPN and
static IP addresses.
I just wanted a quick & dirty solution short-term.

Bugger.
What I was actually aiming for is the ability to forward all traffic
from a PC behind a (couple of) firewall(s) through a single port to a
remote PC, then have the remote PC forward the packets on to their
real destination, and route the replies back.
I was hoping to avoid using VNC via SSH or something, as I wanted the
applications to run on the firewalled PC itself.
Nay matter, thanks for the info.
