Members| Member | Description |
|---|---|
| UdpBlocked |
UDP is always blocked.
|
| OpenInternet |
No NAT, public IP, no firewall.
|
| SymmetricUdpFirewall |
No NAT, public IP, but symmetric UDP firewall.
|
| FullCone |
A 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. Furthermore, any external host can send
a packet to the internal host, by sending a packet to the mapped external address.
|
| RestrictedCone |
A 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. 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.
|
| PortRestrictedCone |
A port restricted cone NAT is like a restricted cone NAT, but the restriction
includes port numbers. 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.
|
| Symmetric |
A 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. If the same host sends a packet with the same source address and port, but to
a different destination, a different mapping is used. Furthermore, only the external host that
receives a packet can send a UDP packet back to the internal host.
