Thanks everyone for the quick responses.
Gordon, your solution is the only one that has worked for me so far. Simple
and effective way too. Thanks for that.
I don't understand why none of the iptables forwarding commands are working.
Before the command is issued, when a remote user attempts to connect to that
port, you get the Connection Refused message (as you would expect). After
you issue the commands and then make a connection it just sits there and
times out. I'm not sure why that way isnt working, but using xinetd works
for me, and is probably easier to manage. For now, that way is fine by me.
Thanks for everyone's help. Greatly appreciated.
