Port Forwarding for Minecraft Server on Netia Spot BF43DO: DMZ Alternative Solution

Hi !
I find this forum searching something in Polish/English to solve my problem, without success...

So I'm here as a noob to ask some help.

I'm trying to use the port forwarding of a Netia Router, but seems I do something wrong.

If I use only the forwarding the server is not accessible from eternal user, but if I put my ip in DMZ the server is showed online.

But keep my Pc on DMZ ... nope ...

Try different combination, but nothing happen, as internal user i can see the server.

Is a server for Minecraft.

Thanks to all for the help

Regards,
Andrea
