[D1] Port 6112 and UDP Packet Processing

Exactly. Port Forwarding should not be required to connect to battle net and create OR join a game. That's how the battle net worked in 2016 when I last tried to connect with Diablo 1.

You DO need the port forwarding setup to allow other players to join a game you created, this is because Diablo 1 hosts the game on your PC, not on the server.

The fact that
- one of multiple PCs in a household
- anyone who cannot perform the port forwarding setup (because of NAT or ISP's router - most common cases)
- or anyone connecting from a multi-layered network
cannot even join other people's games is seriously wrong. It worked before. It works today when I connect to a private realm. Why can't it work on the Global gateway?
Estou tendo o mesmo problema, que os demais, comprei o jogo e nao consigo logar no battle.net. Apresenta o problema de conexão port 6112. Gostaria que a blizz fizesse um novo patch para resolver este problema. Ja tentei reiniciar, rodar como adminstrador, desligar o firewall, e o problema persiste. Shame blizzard
Just bought the game and cant play battle.net.

Opened ports 6112-6119 TCP/UDP.
Added Diablo.exe from the gog program file to my firewall
Tired running it as "Administrator"

Id really like to play online. Any suggestions?
I have the same problem. I tried to do everithing
1)Ports 6112-6119 (TCP & UDP) in my router are opened.
2)Firewall rules for in- and out-coming for the Diablo.exe program are opened in windows firewall
3)Antivirus is off

but still not working! I wanna play online, suggestions?
If it helps at all guys, I bought the GOG version and I suppose the patch they released fixes whatever issue I was having. So basically the original release back in the 90's will not work? derrrrrrrrpppp

Have you tried to right click and run the game as administrator? We released an updated version of the Diablo I client on [url="https://www.gog.com/game/diablo"]GoG [/url]that may also help as it contains a lot of bug fixes and has been updated to work on a modern OS.

Thank you.
Hey Zuvk, appreciate the response man!

Everything worked out through buying the GOG version, which really wasn't too expensive.

Do you think there will be a publicly available patch for those who own an original copy? Might sound like a nerd, but I've had this baby since the 90's and look at it like a treasure, and would love for it to be of a better use other than something that sits in a cd rack. Good for single player at-least lol

That's unlikely. Basically, there's no way for us to validate ownership on the old client, though as I also have my old copy I totally trust you've still got yours. If something like that were to happen in the future we'd have to come up with a new distribution method to prevent piracy, so for now the GoG client is your best bet. Thanks for the follow up!
My problem was solved!
I talked to my Internet Provider because the filter that port. At the moment they opened my ipv4, I can create games on battle.net.
Info: I have the GoG version.
I have same problems about port 6112, is the ipv4 thing something you can set on your router/ISP box or are you obliged to contact them ? (how can you know if it's already enabled?)
