These instructions detail how to setup port forwarding. The scenario is the desire to have telnet's port of 23 be exposed as port 7023 to the outside world.
NOTE: ACS (Access Client Solutions) has many ports that would need to be remapped.
First navigate to
Configure Services pop-up window, as shown below.
NAT tab. Add a new
DNAT entry at the top (needs to be at the top). The
Original IP should be your IBM i public IP and the
Translated IP should be your internal IBM i IP.
Next, select the
Firewall tab and create an entry as shown below. Note the
Source should be
external:Any and the
Destination should be your IBM i public IP with a port of 7023.
Save the entry and wait for the settings to be applied (usually less than 10 seconds).
Now you should be able to telnet to port 7023 instead of 23.
