So, I want to play multiplayer Minecraft on a self-hosted server with my friends, but for some reason, my Port Map application (I'm on a Mac) doesn't recognize the router. I disabled NAT, but soon after had speed problems with the internet. I suspected something weird was going on, so I made a factory reset and re-enabled NAT. I don't want to make my network vulnerable to attacks, so I'm trying to find a way to play on my server without disabling NAT. I tried putting my ip address on the DMZ section in the configuration page, but Port Map still says the router is incompatible. Also, I already have UPnP enabled. Suggestions, anyone?

I have nat type 1 with this router but no upnp. access your router. click on advanced setup, click on configure, click on connection, choose ppp over ethernet llc/snap scroll down and click on save and restart connection. call your internet provider and get the username and password for your router. you will need it later. on your ps3, go to network settings, select internet connection settings. the ps3 will ask if you want to continue, select yes.select custom, wired connection, auto detect, PPPoE, enter the username and password you got from your isp, select automatic, automatic, do not use, enable, then press the x button to save, press the x button again to test connection

You want the NAT open for X-box ?

For X-box you will need to open some ports on the router.

Also you will need to reduce down the MTU on the router to 1365.
That will work.
for this you will need to open the router set up.
