![]() ![]() ![]() Hole-punching is possible with normal (full-cone), restricted and port-restricted NATs, which map the same internal address/port consistently to an external address/port. Using a previously established association to permit an arbitrary external address/port to send data to an internal address/port is referred to as hole-punching. Furthermore, only the external host that receives a packet can send a UDP packet back to the internal host. If the same host sends a packet with the same source address and port, but to a different destination, a different mapping is used. Symmetric NATĪ symmetric NAT is one where all requests from the same internal IP address and port, to a specific destination IP address and port, are mapped to the same external IP address and port. Specifically, an external host can send a packet, with source IP address X and source port P, to the internal host only if the internal host had previously sent a packet to IP address X and port P. Port Restricted Cone NATĪ port restricted cone NAT is like a restricted cone NAT, but the restriction includes port numbers. Unlike a full cone NAT, an external host (with IP address X) can send a packet to the internal host only if the internal host had previously sent a packet to IP address X. Restricted Cone NATĪ restricted cone NAT is one where all requests from the same internal IP address and port are mapped to the same external IP address and port. Furthermore, any external host can send a packet to the internal host, by sending a packet to the mapped external address. Normal (Full Cone) NATĪ full cone NAT is one where all requests from the same internal IP address and port are mapped to the same external IP address and port. InformationĪll NAT definitions below are taken from the Internet Society RFC 3489. Comment per the article: "The advisory reveals a command injection vulnerabil.Understanding Different NAT Types and Hole-Punching Applies to…Ī brief explanation of Network Address Translation (NAT) types, how they work with hole-punching and can affect the ability to join Gateway Groups and create tunnels. After properly configuring the open port, port redirection or DMZ host, you can use the public IP address (or domain name) to access the server from both your home or office network as well as from the Internet. It's useful when you run the server inside the network.
