Port opened (with wider option too) on NETGEAR DGN2200v4.
Checked few times with friend in both directions. Unfortunately doesn't work - i can only play with already created lobbies, not own ;(
Any advice guys?
PS it's not first time opening ports, and i had never problems earlier in other games
edit: After two days i check once again, and 2 guys join my lobby without problems! not sure what was that but happy it works -,-
