Ok, so I'm in a bit of a pickle here. Bascially, I'm trying to run a tekkit classic server on my older computer that runs Windows Vista and play on it using my newer computer that runs Windows 7. At my house our Wi-Fi is weird, so we have two routers that are configured separatley. I'm currently using seperate routers for my two laptops. Both of the routers are configured with the 25565 port to allow server connections, so that isn't my problem. When I run the server on the older laptop, everything works fine. When I try to play on it using my newer laptop however, I can't connect. I've tried using both the internal and external IP's of both routers but neither of them seem to work. I'm considering changing the routers so that both of my laptops are connected to the same one in hopes of being able to connect to the server. If anyone has any advice of how I could fix my issue at hand, I would appreciate it. Thanks!
