And i see my server only in LAN , not in internet
How you get internet on your PC? If through Router, then in router settings you have to port forward from your router to your PC specific port which you wish to have for LU.
If that doesnt work, then, you have bad internet connection (without your own IP adress). In such case, you have to host your server somewhere else than your PC. For example at Vrocker-hosting or else on any VPS in the world with x86 architecture only.
