Tip: To ensure that tunnels stay active, after completing the wizard, manually
edit the VPN policy to enable keep-alives, which periodically sends ping
packets to the host on the peer side of the network to keep the tunnel
alive. For more information, see Configure Keep-Alives on p
age 260.
Tip: For DHCP
WAN configurations, first set up the tunnel with IP addresses.
After you have validated the connection, you can use the wizard to
create new policies using the FQDN for the WAN addresses.
