Our NAT - based on V6 and onwards - is searching for a any free avaliable port for a connection (TCP or UDP) from a private to a public network.

By this, it doesn´t mather which Source-Port the internal device uses.

Example - two PCs surfing on www.heise.de:

172.16.0.45:8768 -----> 172.16.0.1:80 - Official-IPaddress:2050 -----> www.heise.de:80

172.16.0.78:4566 -----> 172.16.0.1:80 - Official-IPaddress:2051 -----> www.heise.de:80

This is the innovaphone implementation of automatic/dynamic NAT for connections from private to public networks.


Moreover, there's a configurable static NAT for connections from public to private networks. Therefore you configure forwards for certain ports to certain internal addresses.

Example:

All traffic from public network on port UDP:5060 is forwarded to the PBX.
