Why can't I host a Minecraft FTB server?

When I try to host a FTB server the CMD window says that it is done but when other people try to connect it says "Can't connect to server". I can connect using the hamachi ip address and local host.
I'm running the server in offline mode and have even tried turning off the mcafee firewall.Here is a copy of the properties file.
