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.
