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.
NAT Traversal 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 4500 packets to the remote IPSec
router behind the NAT router.
