The Gateway Access Utilities package from Sterling Software.
Supports access to the Internet through a network firewall without
requiring that users have accounts on the firewall host itself.
These are modified TELNET and FTP programs that work in a "proxy"
fashion through the firewall.

The socks package by David and Michelle Koblas.
An Internet "socket server" consisting of a set of client library
routines and a daemon that interact through a simple protocol to
provide convenient and secure network connectivity through a
firewall host.

Tcpr is a set of perl scripts that enable you to run ftp and telnet
commands across a firewall. Forwarding takes place at the application
level, so it's easy to control.
Tcpr consists of an inetd-type server that interprets commands,
a relay program, and a client that talks to the server.
