Network Address Translation (NAT) network environments use private internal IP
addresses for devices within the network, while using one external IP address to allow
devices on the LAN to communicate with other devices outside the LAN. If your system is
connected to a LAN that uses a NAT, you need to configure NAT Public (WAN) Address
so that your system can communicate outside the LAN.
Note
NAT feature parameters on the system are described below:
Parameter Description Configuration Method
Static NAT
Specifies whether the system
should determine the NAT public
address automatically.

Disabled—the system does
not use the NAT feature.

Manual—the system uses
the manually configured
NAT public address.

Auto—the system obtains
the NAT public address from
the specified Yealink server.
Default: Disabled
Remote Control
Web User Interface
NAT Public IP

obtained from the Yealink server
if the NAT is configured to Auto,
or configures the NAT public

If H.460 Firewall Traversal is enabled on the system, H.323 calls will automatically ignore
the static NAT settings. For more information on H.460 Firewall Traversal, refer to
