4.1.2.3 Configuration/IP/H.323 NAT
H.323 NAT is an add-on for the general NAT function. This function is only nee-
ded if the telephone connects the private network with the public network. The
telephone must therefore represent a connecting point between the two net-
works. This function enables H.323 calls between private and public networks.
The
Status
section provides you with a brief overview of the registered users
(
Registered Clients
) and the calls currently active (
Active Calls
).

Clicking the interface ID (

ming H.225/signalling messages are routed.

played in the PPP State overview page if it is enabled.

only devices with an ISDN interface. However, PPTP (VPN)
and PPPoE (DSL) connections using the Ethernet interface
(ETH) are also possible.

A descriptive name for the interface can be entered here.
This name is used for the overview in the PPP State submenu
(see chapter entitled “
