connecting through a firewall

i was wondering if anyone knew how to connect to a mud or mush through a firewall?

See Proxy server support wanted

Basically the answer is that firewalls are supposed to stop you connecting to things the system administrator doesn't want you to, and unless you can work around that you are probably out of luck.

There are ways around firewalls, to a certain extent. The administrator may allow certain ports out (eg. the telnet port, 23). If you could find an account on a machine on the other side of the firewall where you could get shell access, you could conceivably "leapfrog" via port 23 to the MUD port on your target machine.

However if they are blocking port 23, or if you can't find such an account, then there may be nothing you can do about it.
