I've opened up ports 6112-6119, TCP & UDP on my Router.
I've opened up ports 6112-6119 TCP & UDP, plus 3724 TCP on my Firewall.
Still, nothing, Any help?
have you added Diablo.exe to allow on Public/Private networks in Windows Firewall?
there may be already an entry, but "Allow another app" anyway and browse to GOG folder's Diablo.exe
first time usually you will see the red 6112 message, cancel and click bnet again and it should be ok.
