(config vpn ipsec tunnel ipsec_example)>
The IPsec tunnel is enabled by default. To disable:
(config vpn ipsec tunnel ipsec_example)> enable false
(config vpn ipsec tunnel ipsec_example)>
4. (Optional) Set the tunnel to use UDP encapsulation even when it does not detect that NAT is
being used:
(config vpn ipsec tunnel ipsec_example)> force_udp_encap true
(config vpn ipsec tunnel ipsec_example)>
5. Set the firewall zone for the IPsec tunnel. Generally this should be left at the default of ipsec.
(config vpn ipsec tunnel ipsec_example)> zone zone
(config vpn ipsec tunnel ipsec_example)>
To view a list of available zones:
(config vpn ipsec tunnel ipsec_example)> zone ?
