That IP is a (YOUR) LAN IP address which is NOT accessible from a PC not running within YOUR LAN (internet routers do not forward such addresses). A FAQ thread deals with WAN access "Q: How do I configure so that the server allows WAN access?"

Make sure terms like "LAN", "WAN",... are not a mystery fro you (wikipedia,...) as you MUST understand them in case you're planning to run ANY server.
