common use for this functionality is to add SSL encryption to
an incoming TCP connection prior to sending it along to the
remote host.
The Network Translation table is used to define network
mappings for TCP pipes. You must first specify the incoming
TCP port to which your device or application will connect.
Then, you must specify the outgoing hostname and destination
TCP port for the TCP pipe.
You can also specify the source TCP port for the outgoing TCP
connection. Usually, this should be set to 0 to allow automatic
selection of the source port. However, if you have a firewall
that imposes limits on source TCP ports then you may need to
set this to something specific. Note that if you specify
something other than 0, you will be limited to only 1 TCP pipe
at‐a‐time for any given destination port.
Protocol Settings
For each host (peer) you will make an outgoing connection to,
you need to specify the protocol options used for that host. For
each host, select the Host from the “Edit settings for a different
peer” selection box. Select “Add a new peer definition” link to
add a new host.

The hosts are identified by their IP address or Hostname and
TCP port. You may also specify wild cards. Specific host names
and/or port numbers take precedence over the wild cards. An
asterisk for the IP address/hostname (for instance “*:443”)
