■When you specify the ATMP Partner IP Address, and the address is in the same subnet as the Remote IP Address you speciﬁed in the IP Proﬁle Parameters, you can specify the route (Tunnel Via Gateway) by which the gateway partner is reached. If you do not specify the ATMP Partner IP Address, the router will use the default gateway to reach the partner and the Tunnel Via Gateway ﬁeld is hidden. If the partner should be reached via an alternate port (i.e., the LAN instead of the WAN), the Tunnel Via Gateway ﬁeld allows this path to be resolved.

■You can specify a Network Name. When the tunnel partner is another Netopia router, this name may be used to match against a Connection Proﬁle. When the partner is an Ascend router in Gateway mode, then Network Name is used by the Ascend router to match a gateway proﬁle. When the partner is an Ascend router in Router mode, leave this ﬁeld blank.

■You must specify a Password, used for authenticating the tunnel.

Note: The Password entry will be the same for both ends of the tunnel.

■For Netopia-to-Netopia connections only, you can specify a Data Encryption algorithm for the ATMP connection from the pop-up menu, either DES or None. None is the default.

Note: Ascend does not support DES encryption for ATMP tunnels.

■You must specify an 8-byte Key String when DES is selected. When encryption is None, this ﬁeld is invisible.

■You can specify that this router will Initiate Connections, acting as a foreign agent (Yes), or only answer them, acting as a home agent (No).

■Tunnels are normally initiated On Demand; however, you can disable this feature. When disabled, the tunnel must be manually established through the call management screens.

■You can specify the Idle Timeout, an inactivity timer, whose expiration will terminate the tunnel. A value of zero disables the timer. Because tunnels are subject to abrupt termination when the underlying datalink is torn down, use of the Idle Timeout is strongly encouraged.

It is difﬁcult to specify the address that will be served to a particular client in all circumstances. However, when the address server has been conﬁgured, and the clients involved have no prior address serving interactions, the Netopia R910 will generally serve the ﬁrst unused address from the ﬁrst address pool with an available address.
