Hi!
I’m trying to figure out how to configure my MikroTik so that my POS terminal works correctly.
So far I know how to forward ports to a local server but how can I just open In and Out ports like 57173, 21405, 11405 for IP 192.168.1.60.
The POS terminal has to communicate with a public server (transfer and receive data).
Do I have to make src and dst NAT rules for each port or do I just open firewall input and output for these ports?
Sorry for my bad english.
input and output is for communication to/from the router, so you do not need to open any ports there.
You just need to add dst-nat rule to forward ports to the terminal

What if I have 2 POS terminals and they are working with the same ports and connecting to the same public IP?
I have a old 3Com router with a “Special applications” function that allows just to open the ports without NATing them to a local IP.
Thank You mzr!
Address lists should fix my problem, found it in your link.
