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).
4.1.2.4 Configuration/IP/PPP Config
The parameters for the DSL and VPN connections are set here.
Clicking the interface ID (PPPn) opens the respective configuration page, on
