Router hidding server! Help please

[Cramuka]

Hi, how do I create a sever so I can play with my friends, using a router?
It is hiding my server. Can someone explain what should I do? What doors should I open, I don't know. Help me please :)

You want portforwarding for those ports. Look in the manual of your router on how to do that. Hyper already provided you with the ports.
