If anyone has had success getting the game to run please post feedback. We used the same method mentioned at the top of this comment. Me and a friend spent a whole day fixing these problems so we could do coop over the internet, we eventually just switched to a VPN, which worked a lot better than Hamachi. I suggest disabling the Encryption and Compression, or just leave the compression on in Hamachi. (It complains about unregistered address 5.x.x.x in the debug messages as well) 3 - There seems to be some timeout which is set extremely low, and over hamachi it takes up to 3 seconds to connect sometimes. I think the packets expect to be received through your LAN device, but they come through 5.x.x.x instead causing some more crap to break. 2 - The wrong device gets bound when you have multiple adapters. I think this method fixes it because it bumps up the priority of the Hamachi adapter. The game has multiple issues that may or may not be fixed using this method: 1 - For some reason, the UDP broadcasts don't route through hamachi even when the routing table has the hamachi devices with metric 1 for 255.255.255.255. You should now be able to host or join a game through LAN. I'm not sure if the client or server or both need to do this but here goes: 1 - Start hamachi and join a network 2 - Disable all your adapters from the Network Connections menu in Windows, except for the virtual Hamachi adapter, then start the game 3 - Once you are in the game menu, re-enable whatever adpaters you disabled. Here is an alternate patched executable for version 1.0 only: IEYEABECAAYFAklfBEQACgkQ3PGpByoQpZFpGQCfbTxZJAsZiyHGw0r5KFB9XOyqĬheck this comment for how to play over the latest Hamachi. If you can't switch to nazi zombie mode, the host must type 'ui_mapname map' in the console.Įx: 'ui_mapname nazi_zombie_prototype' will change to the zombie map the game comes with

The server does not need it, only the clients need it. This memory patch will enable you to join LAN servers.
