Secure Computing SG300 User Manual page 156

Note
The example shown in the screenshot above forwards the SSH (secure shell) protocol to
an internal server (barry's server). SSH allows encrypted remote access, typically to a
server running Linux, BSD or another Unix-like operating system.
In this example, port 2222 is used rather than the standard SSH port of 22. This is to
allow remote access using SSH to the SnapGear unit itself, which runs an SSH server on
port 22. So a remote user connects to port 2222 on SnapGear unit's Internet address in
order to access port 22 of barry's server.
The following fields are displayed:

restrictive filter rule through Rules.
