Typically, third party hosts on the public transit network are used to establish UDP or TCP port states that may be used for direct communications between the communicating hosts, however ICMP hole punching requires no third party involvement to pass information between one or more NATs by exploiting a NAT's loose acceptance of inbound ICMP Time Exceeded packets.Once an ICMP Time Exceeded packet reaches the destination NAT, arbitrary data in the packet expected by the NAT allows the packet to reach the destination server, allowing the destination server to obtain the client's public IP address and other data stored in the packet from the client."@en }
