UnverifiedSTUN servers help devices discover their public IP addresses and mapped ports, and are suitable for cone NAT scenarios, but symmetric NAT causes STUN direct connection to fail.84% similarVerifiedTailscale uses a combination of STUN-like protocols to detect public network addresses and UDP hole punching for NAT traversal, employing a strategy of attempting direct connection first and falling back to relay.83% similarUnverifiedReverse tunneling technology allows intranet nodes to actively establish persistent connections to public internet servers, and is a classic solution to the NAT traversal problem.73% similarUnverifiedPort forwarding is a static mapping rule established on a NAT router that forwards external port traffic to an intranet host by modifying the destination address of packets (DNAT).72% similar
