Is NAT Type Detection Tool Worth It? FAQ & Reviews
NAT (Network Address Translation) describes how your router translates private addresses and how reachable you are from the internet. Standard classifications include Open Internet, Full Cone NAT, Restricted Cone NAT, Port-Restricted Cone NAT, and Symmetric NAT.
Generally, Open Internet/Full Cone maps to PS5 NAT Type 1 (Open), Restricted/Port-Restricted Cone often maps to PS5 NAT Type 2 (Moderate), and Symmetric NAT or CGNAT commonly maps to PS5 NAT Type 3 (Strict). Actual results depend on router, firewall rules, and ISP policies.
You can improve your NAT type by enabling UPnP on your router, configuring port forwarding, setting your device as DMZ host, updating router firmware, or contacting your ISP for more options.
NAT type directly affects your online gaming experience. Stricter NAT types (like NAT3) may cause difficulty connecting to game servers, poor voice chat quality, longer matchmaking times, and inability to host game lobbies.
