Section 3: Policy Setup (continued)

IPSec Policy Options
The IPSec Policy Options console consists of three sections: Tunnel Attributes, Dead
Peer Detection Feature, and Options. The console allows you to set tunnel attributes for
each tunnel. In order for these options to operate they must be enabled on both the remote
and the local side. NetBIOS and Auto Trigger are enabled by default.
NOTE: When you make changes to this menu you must click the Set button and then the
Update button on the Policy Setup to save your settings.
Tunnel Attributes
This section displays various tunnel attributes configured for the tunnel as well as the
status of the VPN tunnel. Use this to aid you in the configuration of the tunnel options.
Figure 18-e. Dead Peer Detection Console.
Dead Peer Detection Feature is a countermeasure designed to prevent wasted
bandwidth and CPU cycles in the event that the remote side VPN tunnel is terminated.
Instead of sending data and waiting for a response, the link is actively monitored. If it
ever goes down, the link will be handled by the set user preference. By default this
feature is disabled.
Not all VPN Gateways have this feature. If you are connecting to a non-XiNCOM VPN
gateway it is recommended that you keep this feature off. Otherwise, frequent
disconnects may result because the remote side (non-XiNCOM VPN) will not reply.
