WC3 Unable to join games

Im having troubles to join games and my friends on the external network has same issue. They can log in to a server but if someone creates new game, we can see it on the list, but no one can join it. I tried even with 2 clinets from my own network. I have ports forwarded, no changes were made to address_translation.conf, even on default settings no one can join.

Ports I have forwarded:
6112 to 6119,4000,6200

All ports default

My setup is:   Internet -> first router ->second router ->pc with the server on
Internet dynamic IP -> 172.20.0.1 network -> 192.168.1.1 network -> 192.168.1.20 my pc ip, static [tried with two clients on my pc, one on virtual machine with ip of 192.168.20.20)
Ports are open on 192.168.1.1 network, 172.20.0.1 network is bridge, and it works because I can host games on official battle net or other services work great.

The log when trying to join is:
Nov 08 16:30:00 [info ] handle_bnet: Told Mutual Friends your in game test

Nov 08 16:30:10 [debug] pvpgn::bnetd::_client_gamelistreq: [624] GAMELISTREPLY sent 1 of 1 games

Which makes me think there might be a need of editing address_translation.conf as it uses my first router internal IP... but how would I go about it?

This issue also might be disabling my 'ladder matchmaking' as it finds no players.

Edit: even if i try to host with Ghost++, it connect to the realm, hosts a game but I can not join it. All on local pc, but this time game is not shown on the list so i enter its name by mysself. When trying on official battlenet, it works. Of course i change game version, point to the right wc3 directory etc

tldr; how would I go of hosting pvpgn on my machine and also running ghost++ and my own WC3 client on my machine and let others on external network to join my games, let me to join theirs and also to let me to join a game hosted by my own bot. Im nearly sure it is something to do with adres translation.
