ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336Gv2 Reference Manual
Tip: To assure tunnels stay active, after completing the wizard, 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.
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.
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.
8. Enter the local LAN IP and Subnet Mask of the remote gateway in the Remote LAN IP
Address and Subnet Mask fields.
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.
9. Click Apply to save your settings. The VPN Policies screen shows that the policy is
enabled.
10. If you are connecting to another NETGEAR VPN firewall, use the VPN Wizard to
configure the second VPN firewall to connect to the one you just configured.
