Nat type Strict, how to change it to Moderate or Open? Behind a router from my ISP.

Hi. I'm having a Nat type strict, checked using the Xbox networking method on Win10 (Settings---Gaming---Xbox Networking).

Firstly, the problem I suspect, is I'm behind a router from my ISP. as my normal setup (ISP cable to my Wan port) I see the status page, and I have a Wan IP of 192.168.254.X I tried the following:

- Set the router as bridge mode (Give new lan IP same as ISP 192.168.254.X (before it was 192.168.0.X) and disable DHCP), still Nat strict.

- Set router as bridge mode (Give new lan IP and disable DHCP) and put laptop's IP as DMZ, still Nat strict.

Is the only solution left is to a buy static IP from ISP? and after buying one what should I do? call them? Sorry I never bought a static IP before.
