Hey guys, just started a new Tekkit server, and everything works fine... for me. I can connect to my own server, but my friends (the reason i created the server in the first place) cant connect to me. The server is up, external ip is right. They tried typing in the port after ext. ip (e.g. 555.555.55.55:55555) and it didn't work either. everything was loaded and downloaded correctly, did NOT use hibachi, made server from my computer using simpleporforwarding. I'm not sure if they simply cant connect to me, or if i had forgotten something. Thanks
