DESCRIPTION
Select this check box to activate this VPN tunnel. This option determines whether
a VPN rule is applied before a packet leaves the firewall.
Select this check box to have the Prestige automatically re-initiate the SA after
the SA lifetime times out, even if there is no traffic. The remote IPSec router must
also have keep alive enabled in order for this feature to work.
Select this check box to enable NAT traversal. NAT traversal allows you to set up
a VPN connection when there are NAT routers between the two IPSec routers.
The remote IPSec router must also have NAT traversal enabled.
You can use NAT traversal with ESP protocol using Transport or Tunnel mode,
but not with AH protocol nor with manual key management. In order for an IPSec
router behind a NAT router to receive an initiating IPSec packet, set the NAT
router to forward UDP port 500 to the IPSec router behind the NAT router.
so it is generally recommended. Manual is a useful option for troubleshooting.
