Others can't connect to my forge server 1.12.2

[Felipe Pozzetti]

My friends can't connect to my 1.12.2 forge server (forge-1.12.2-14.23.5.2859).
I've already tried port-forwarding (TP-LINK EC220-G5)
Already disabled my windows firewall + created TCP/UDP rules

I can connect using "localhost" but others can't connect using my public ip...

I have a machine connected by team viewer to constantly test if it's working or not....

I did the EXACTLY same thing on my friend's PC and the server worked perfectly on his, the problem is that his PC can't handle game+server at same time (low ram)

Please help me with this.
