Answer 2

Sounds like you are running a server from your personal PC from home? If this is the case, you need to make sure the gameport you have choses in Server.Properties have been opened on your Router/Firewall.

This will do so other people outside your LAN can connect to the server.

To open the port, Google "Minecraft Port Forwarding" to find a guide and tools to do it.

Answer 3

I have published a guide that should fix this problem. How to Port Forward.
