If you suspect double NAT
If you are using both a carrier-provided modem and your own router, switching the modem into bridge mode collapses the setup back down to a single NAT, which resolves most Strict NAT issues at the root rather than working around them port by port.
If this is your first time forwarding ports
If UPnP alone does not solve it and you need to forward ports manually, start by confirming how to reach your router's admin page and the basic forwarding steps before entering the specific PS5 or Xbox port numbers.
Frequently Asked Questions
My NAT type shows Strict but my games work fine. Do I still need to fix it?
Not necessarily. If you are not actually running into matchmaking or party chat problems, there is no urgent need to change anything β NAT type is just an indicator of how smooth those specific features are likely to be, not something that blocks a game from running.
Once I get an Open NAT type, does it stay that way?
Not always. Rebooting your router or changing its settings can knock you back down to Strict or Moderate. If UPnP is enabled, ports usually reopen automatically, but if you forwarded them manually, it is worth occasionally checking that the rules were not reset.
