NAT
NAT (Network address translation) converts an IP address of an e. g. private
network into an IP address of the public network. All computers that commu-
nicate with each other within a private network, receive Internet access via
only one IP address. The internal IP addresses of the private network are
not accessible for the Internet.
SIP NAT-Traversal
If NAT traversal is switched on and a query is sent from a local IP address
to the public network, the sending IP address is swapped with the public IP
address. This function is performed in the reverse direction for the reply.
