To set up an ATMP tunnel, you create a Connection Profile including the IP address and other relevant 
information for the remote ATMP par tner. 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 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 
 for information on creating Connection 
Profiles.
The WAN Event Histor y screens will repor t 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.
