Hi Morkis
Welcome to the Forum.
But until you give us a clue how your 450g is setup, we can’t help you much further? Is there a xDSL modem between your internet and the router? Have you configured any firewall rules to block such traffic? Have you in fact, added any specific rules to allow this traffic to get to a specific PC on your network? Is this for TCP or UDP traffic?
I know, so many questions… and no answer! But until you tell us how your router and your network is setup, we just have to guess. That wastes ours and your time with us both getting nowhere fast.

Usually I can open it, but it was these can not 
Maybe possible create to copy paste script,or something like that?
EDIT: Ahh my firewall failed,working now but one internal ip…
Now how to make that go in all internal IP addresses in my game?

You can’t, unless you allocate a separate public IP to each internal user that needs that IP mapping to them.
