Field Name Description
NAT Traversal Set to Yes to allow the system to be located behind a firewall/NAT.
Set to No if the system is not located behind a firewall/NAT, but has a
public IP address.
NAT Discovery Manual method of setting the system’s firewall/NAT public IP
address. Enter the Public IP address for that setting.
HTTP discovery - This method uses a Radvision HTTP server to
discover the presence of a firewall/NAT and its public IP address
(requires the endpoint to have internet access).
