I need help. I can't seem to port forward my Craftbukkit server to other internet users. I'm the only one that can get on at my house but at anothers it won't let me I give them my ip address but that doesn't work either can someone please send me a link for something really helpful. I don't want use Hamachi!

" I can't seem to port forward"

Why not? Have you tried? You can't just say that its not working and expect a direct answer. Log into your router, enable port forwarding, forward port 25565 to your ip address, and you're done.
