So I have some rules on my server for my VPN, but my partner does port forwarding if needed for my customers. I want to know how to do it myself but he doesn't want to tell me. Now I found these rules on my server, could anyone translate it to the command that was entered? Like the command my partner typed in putty to add this rule, so I can learn from it.
If possible explain what everything does aswell please :).
