LABEL DESCRIPTION
IPSec Setup
Active Select this check box to activate this VPN policy. This option determines whether
a VPN rule is applied before a packet leaves the firewall.
Keep Alive Select either Yes or No from the drop-down list box.
Select Yes to have the ZyXEL Device automatically reinitiate 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.
NAT Traversal This function is available if the VPN protocol is ESP.
Select this check box if you want to set up a VPN tunnel when there are NAT
routers between the ZyXEL Device and remote IPSec router. The remote IPSec
router must also enable NAT traversal, and the NAT routers have to forward UDP
port 500 packets to the remote IPSec router behind the NAT router.
Name Type up to 32 characters to identify this VPN policy. You may use any character,
including spaces, but the ZyXEL Device drops trailing spaces.
