UnverifiedThe core principle of intranet penetration is to establish a relay node on a public server, where the local environment actively connects to the public server via a persistent connection, and external requests are forwarded to the local environment through the established connection.76% 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.75% similarUnverifiedThis reverse-proxy-plus-outbound-tunnel architecture allows local machines to expose services without opening inbound ports, without a public IP, and bypassing NAT and firewall restrictions.71% similarUnverifiedTunnel connectors are deployed within an intranet and actively establish outbound encrypted tunnels to public-facing nodes to bypass NAT and firewall restrictions, which is the common approach used by similar tools such as Cloudflare Tunnel and frp71% similar
