H.323 NAT is an add-on for the general NAT function. This function is only needed if the telephone connects the private network with the public network. The telephone must therefore represent a connecting point between the two networks. This function enables H.323 calls between private and public networks.
- Enable H.323 NAT: Enables NAT for H.323 VoIP calls.
- Require authentication: H.323 authentication is obligatory if the check box is checked. This setting protects against externals attacks on the private network. H.323 messages without authentication are not routed to the private network.
- H.225/RAS destination: IP address of the server in the private network, to which incoming H.225/RAS messages are routed.
- H.225/Signalling destination: IP address of the server in the private network, to which incoming H.225/signalling messages are routed.
