3. Create a Connection Name. Enter a descriptive name for the connection. This name used to
help you manage the VPN settings; is not supplied to the remote VPN endpoint.
4. Enter a Pre-shared Key. The key must be entered both here and on the remote VPN gateway,
or the remote VPN client. This key must be a minimum of 8 characters and should not exceed
49 characters.
5. Enter the Remote and Local WAN IP Addresses or Internet Names of the gateways which
will connect.
• Both the remote WAN address and your local WAN address are required.
• The remote WAN IP address must be a public address or the Internet name of the remote
gateway. The Internet name is the Fully Qualified Domain Name (FQDN) as registered in
a Dynamic DNS service. Both local and remote endpoints should be defined as either
FQDN or IP addresses. A combination of IP address and FQDN is not allowed.
6. Enter the local LAN IP and Subnet Mask of the remote gateway in the Remote LAN IP
Address and Subnet Mask fields.
Tip: To assure tunnels stay active, after completing the wizard, manually edit
the VPN policy to enable keepalive which periodically sends ping packets
to the host on the peer side of the network to keep the tunnel alive.
Tip: For DHCP WAN configurations, first, set up the tunnel with IP addresses.
Once you validate the connection, use the wizard to create new policies
using FQDN for the WAN addresses.
Note: The Remote LAN IP address must be in a different subnet than the Local LAN
IP address. For example, if the local subnet is 192.168.1.x, then the remote
subnet could be 192.168.10.x. but could not be 192.168.1.x. If this information
is incorrect, the tunnel will fail to connect.
