what is the problem!!

You must forward port 27015 (on your router) for people to be able to connect to your server.

You'll should forward the query port (27017 by default) for people to see your server on the list.

the problem that my ip is always changing

Ah.

/charr

the problem that my ip is always changing

You need to set an IP reservation for your computer, if your router's DHCP allows it.

If not, you can just manually set your computer's IP, so that it will never change. Keep in mind that when manually setting the IP, you'll also need to add the subnet mask, default gateway (your router's IP) and default DNS
