Okay, so I have a perfectly fine running tekkit server in the .bat file type. It opens the command prompt and all that to host the server and works fine. However, when I try to host a Hack/Mine server it is in the .jar file. It starts up the server fine, however no one can connect via ip address. The only way I am even able to connect is through the localhost ip address. Does anyone know what the issue could be?
