About ATMP Tunnels

To set up an ATMP tunnel, you create a Connection Profile including the IP address and other relevant information for the remote ATMP partner. ATMP uses the terminology of a foreign agent that initiates tunnels and a home agent that terminates them. You use the same procedure to initiate or terminate an ATMP tunnel. Used in this way, the terms initiate and terminate mean the beginning and end of the tunnel; they do not mean activate and deactivate.

ATMP is a tunneling protocol, with two basic aspects. Tunnels are created and torn down using a session protocol that is UDP-based. User (or client) data is transferred across the tunnel by encapsulating the client data within Generic Routing Encapsulation (GRE). The GRE data is then routed using standard methods.

ATMP configuration

ATMP is a Datalink Encapsulation option in Connection Profiles. It is not an option in device or link configuration screens, since ATMP is not a native encapsulation. The Easy Setup Profile does not offer ATMP datalink encapsulation. See "Creating a New Connection Profile" on page 2-24for information on creating Connection Profiles.

The WAN Event History screens will report VPN tunnel events, such as connections and disconnections, as Channel 4 (and higher) events.

To define an ATMP tunnel, navigate to the Add Connection Profile menu from the Main Menu.
