NAT
NAT, Network Address Translation, is used in small LAN’s, often home offices, when a PC
and a videoconferencing system is connected to a router with NAT support. NAT support in
the videoconferencing system enables proper exchange of audio/video data when connected
to an external videoconferencing system (when the IP traffic goes through an NAT router).
When NAT is On, the NAT Server Address will be shown in the startup-menu: "My IP
Address: 10.0.2.1 (NAT)".
