This document explains what happens to the source IP of packets sent to different types of Services, and how you can toggle this behavior according to your needs. 1:1 NAT (Network Address Translation) is a mode of NAT that maps one internal address to one external address. But the shortage of IP addresses is only one reason to use NAT. The NAT box looks up the packet's details (source IP, source port, destination IP, destination port) in its NAT mapping tables and performs a reverse translation. NAT operates on a router, usually connecting two networks together, and translates the private (not globally unique) addresses in the internal network into legal addresses, before packets are forwarded to. Tekniken gör det möjligt att ansluta många datorer till en internetanslutning med en eller några gemensamma IP-adresser. Up to 32 VoIP extensions are supported.
