Here is my situation, I have a Tekkit server that I want to play with my friends on. I have it all installed, I can run the batch launch just fine and it will run. I can go and look on the server list and it will be up with a 5 bar connection. But, my friends cannot get onto the server, it says no connection for them at all. I thought it was from a lack of RAM going to the server, so I edited the batch launch, and injected it with 6G's of RAM, it still didn't work. Then I tried to disable my computers firewall, it still didn't work. Can someone help? Did anyone have the same problem? If so, how did you fix it? Thanks
