Diablo 1 HD Hellfire Mod | Awake

So me and my brother finally started multiplayer together on LAN. Everything worked great. After playing, I checked out my Belzebub character, then went to bed. Trying to play again today and I get the error message:

"Failed to Join Game. Connection has been Rejected by Host Computer."

It worked fine yesterday
Both computer have allowed Tchnerbog through firewall
We have tried hosting on both computers
IP addresses have been triple checked.

Anyone having similar problems or have I just missed something obvious?

Are you using some program to run the LAN or the computers are in a direct conection?

If you are usin Hamachi:

Try to disable all the firewall in the both computers.

You can use Tunngle or Hamachi and everything should works fine. (Even with enabled firewall)

Noktis is right. I tested Hamachi here and it worked perfectly.

Huh. I tried various ways to get us playing together again. Tried using Hamachi, Tunngle, altering networking settings, windows repair tools, etc, etc. Turns out it just needed a simple router reset.

Damn, the solutions was far more simple than I anticipated...haha
