Collaborate Desktop: User Guide 97
Enable NAT If your organization uses NAT when communicating with parties
in another LAN or WAN, type the external address for your
videoconferencing device.
NAT helps protect a LAN from exposure to unwanted traffic by
providing one single external address to remote users. NAT
uses a system of local and external addresses to hide a LAN's
users from other networks. A NAT server translates local parties'
addresses to an external address, which is then used to identify
the local party to remote parties. Therefore, remote parties use
this external address to call the local party, without knowing its
actual local address.
