No, unfortunately not.   We have a similar setup where I work.   It is
possible to connect to an arbitrary port through the firewall by going
through the telnet gateway, though, and I've considered hacking sup to
make the initial connection through the gateway before starting its
protocol.   The only problem is that our telnet gateway doesn't quote
code 255 properly (this is the Telnet command introducer), so it
wouldn't work with the current release.   Sigh.

Another alternative would be to provide a hacked ftp server on
sun-lamp which, if you send it a ``SITE SUP'' command, would
establish a SUP connection to you on the port you'd given.   Then
you'd hack sup to do an initial ftp protocol to establish its sup
protocol connection.   This has the advantage of being certain to work
through any firewall that properly supports ftp.

Unfortunately, all of these solutions require a noticable programming
effort.   Now that I have an internet connection at home, it's not
worth it to me...   :'(
