I have 2 port exceptions in Windows Firewall, both for "25565", one for TCP, one for UDP.
My server was working before I went back up to college during march break. I just came home from college for good, and started the server up again. Windows Firewall still has both port exceptions.
When I went into my routers page, under Virtual Servers, I noticed that the Private IP section of the port things still said 192.168.2.5 which was the old IPv4 from before march break. Upon doing an ipconfig, I noticed my IPv4 had changed to 192.168.2.3.
I've already changed the port forwarding in my router page, so hopefully the server should work now.
