Our NAT, based on V6 is searching for a any free avaliable port, for a connection (TCP or UDP) from private to public network. Dosen´t mather , what Source-Port the internal device use.
for example (two PCs surfing on www.heise.de):
172.16.0.45:8768 -----> 172.16.0.1:80 - OfficialIPaddress:2050 -----> www.heise.de:80 172.16.0.78:4566 -----> 172.16.0.1:80 - OfficialIPaddress:2051 -----> www.heise.de:80
That is our implementation of automatic/dynamic NAT for connenctions from the private network to the public network.
Also we have an configurable static NAT for connenctions from public to private network
Therefore you configure forwards for certain ports to certain internal addresses.
Example All what comes from public network on port UDP:5060 forward to the pbx.
