AT&T uses such a system to connect their corporate net to the internet.
They have a machine that runs a proxy telnet, ftp and also does mail.
They have not released the code that I know of, but then I have never asked.  

It works reasonably well from what I have seen.  I am working on some 
network statistics stuff with AT&T folks in NJ and they pick up data every
day from a machine on the local campus here through the firewall machine.
I don't know if they have ported the proxy client to every type of machine
internal to AT&T (like Mac's for instance) but I have seen it work from Suns.
