I'm at work behind a firewall, and I've got a server colocated on a T1 line outside this firewall.
All I want is an SSH session to my server, and I'm trying to figure out a port I can do this on.
I'm bouncing the ssh server around on all the ports I can think of to try.
Ports 80 and 443 are proxied and content filtered, thus obviously out.
ports 22 and 23 are simply blocked.
Ports 20 and 21 (ftp) will allow me to make a passive ftp connection straight through, but it won't let an ssh session through. this is confusing me.
