Hello, My Problem : I can't connect to my server through internet and then My friends are not able to connect too. My configuration : Orange Fibre (not ADSL) WIFI. Windows 7 x64, Java Version 7 Update 21 Antivirus : Nod32 Antivirus 6 (not the smart security just the antivirus version) CraftBukkit version git-Bukkit-1.5.2-R1.0-b2788jnks server.properties : http://pastie.org/8051356 bukkit.yml : http://pastie.org/8051363 run command in a bat file : http://pastie.org/8051369 >plugins 12:14:45 [INFO] Plugins (9): MultiWorld, Backup, GroupManager, Permissions, Essentials, EssentialsChat, EssentialsProtect, EssentialsSpawn, EssentialsAntiBuild Router port oppened, Windows firewall port opened, Hamachi it's working fine but I want it work without Hamachi. http://img4.hostingpics.net/pics/586051Capture2.jpg A port forwarding tester told me that my port is open. Indeed we can see in the server consol that the request was detected "/126.96.36.199:58165 lost connection" http://img4.hostingpics.net/pics/299876Capture.jpg Is it possible that Nod32 antivirus 6 block the port 25565? I didn't find a way to allow a port from it . Thanks for all in advance.
