Hello! Me and my girlfriend usually play FTB together via a single player game set up for LAN. This works perfectly over my local network, however recently we've wanted to be able to play over a server so she can play when I'm not on and be able to log in away from the apartment. My computer is almost always on, so instead of buying a server from a third party I wanted to set up a local server and just port forward Minecraft. At this point, I've created the server on my computer. I run it through a batch file configured like this: java -Xms2048M -Xmx2048m -XXermSize=128m -jar ftbserver.jar nogui There is no IP address assigned, I connect through localhost and she connects through 192.168.1.143 I can play on the server on my client on the same computer no problem. I can also see the server from her laptop, which is sitting on her mini-desk three feet away from me. However, here is my issue: Her ping to connect to the server 2 feet from her laptop is 1039 ms! When she connects it is very laggy for her, not rubberbanding but definitely with a 1 second lag. I then tried creating the server through Hamachi. Again, both computers can see the server. I have 68ms ping to it, but her laptop has 1068ms ping. It's not unplayable, but it's frustrating and we're just going back to the LAN method until I get it fixed. It's doubly frustrating being that the LAN works just fine, too. How can I fix this? We have yet to try to connect anywhere except my apartment. Thanks for any assistance!
