Why does my console say Strict NAT?
Strict NAT can result from double NAT, CGNAT, disabled UPnP or missing port mappings. First identify the WAN IP and number of routers.

Strict NAT can result from double NAT, CGNAT, disabled UPnP or missing port mappings. First identify the WAN IP and number of routers.
CGNAT lets multiple customers share one public IPv4 address. Normal browsing works, but inbound hosting, some games, VPNs and port forwarding may not.
Only after confirming the exact device, protocol and necessity. Prefer UPnP for compatible games or vendor-cloud/VPN solutions; manual forwarding increases exposure.
UPnP improves automatic NAT traversal for consoles but lets trusted LAN devices request mappings. Keep devices secure and avoid it on untrusted networks.
Weak signal, interference, roaming and contention add delay/retries. Compare Ethernet; if wired is good, optimise Wi‑Fi or wire the console.
IPv6 can provide end-to-end addressing where the ISP, router, game and firewall support it, but it does not automatically improve latency and still requires firewalling.
