I created a server using CraftBukkit-1.6.2-R0.1 and for me it works perfectly. I can connect to it fine, run plugins, and everything. My friends can't join though. I left the ip-address in server.properties blank. I know I portforwarded correctly. I have no ideas on what to do and I really want to get this server working. Anybody have any ideas that can help? Please? Edit: I tried checking my ports and it says "Port is CLOSED on this IP Address." I tried letting it through the Windows Firewall, but still nothing I've tried reportforwarding and everything. Somebody please help me! I've been trying to do this for 2 months!
