What Is NAT?
Network Address Translation (NAT) is a method used by routers to translate private IP addresses (like 192.168.1.x) into a single public IP address. NAT was developed to solve IPv4 address exhaustion — instead of every device needing its own public IP, an entire network can share one.
Your router replaces device's private IP with its public IP and tracks which internal device made each request. This translation is transparent to both users and websites.
NAT Types and VPN Compatibility
NAT types (Full Cone, Restricted Cone, Symmetric) can cause problems with VPN connections, especially UDP-based protocols. WireGuard handles NAT traversal well with stateless design and keepalive packets. This is why WireGuard connections are reliable on mobile networks with heavy NAT.
NAT and VPNWG
VPNWG's WireGuard implementation handles NAT traversal automatically using persistent keepalive packets. Whether behind a home router, corporate firewall, or carrier-grade NAT, VPNWG maintains stable connections. VPNWG technical details.
