port 6879

Hi. my first time on this forum.
Using Comodo Internet Security 5.4.189822.1355

Can somebody explain to me how to open port 6879 as Incoming TCP Listen Port for non peer-to-peer connection?

when I test with client program I get following message:
Testing port TCP 6879 …
NAT Error - Connection timed out (xxx:6879).

thank you

Assuming you’re not using a router (if you are you’ll have to port forward) you need to create a Global rule:

Action - Allow
Protocol - TCP
Direction - In
Source Address - ANY or Whatever is appropriate
Destination Address - ANY or the MAC/IP address or the PC
Source Port - ANY or what ever is appropriate
Destination Port - 6879
