Most firewalls block inbound ftp, but not outbound.

If they block outbound ftp they probably block telnet as well.

The old sysadmin way around this (which goes on in a lot of small
companies is some geek sets up a linux box with telnet and ftp above
port 7000... which fully bypasses the firewall if they don't have a good
security admin.

The best way to do this stuff is with ssh and scp anyway.
