- Users first connect to a "proxy" server running on the firewall computer ("out"), which will in turn connect them to the destination system. To use the Ftp proxy, simply ftp to "out" as if you wished to exchange files with it.
- There will be a short pause, and you will be prompted with a Name prompt. Instead of entering the username only, specify both the username and the remote system at once, e.g. smith@ftp.uni-mainz.de or ftp@ftp.cisco.com.
- You will then be prompted with a Password, which will be the password you would have used on the remote system (e.g. your email address on most Anonymous Ftp servers).
- From then on, you are connected to the remote system as if the firewall wasn't involved.

- When you logout from the destination system, the proxy will automatically disconnect you and return to a command prompt on your local system.
