That shouldn't have been necessary, assuming they have port 23 open behind
_their_ firewall.

ssh -L 23:<remote_host>:23 <remote_host>

in one xterm would have set up a telnet tunnel over the ssh connection,
then you just do:

telnet localhost

in a second xterm and you get a secure telnet connection.

Or is the problem that your firewall won't allow outbound ssh connections?
