Netgear FVS318N – Prosafe Wireless N VPN Firewall 참조 매뉴얼

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 

261.

For DHCP WAN configurations, first set up the tunnel with IP addresses. 

After you validate the connection, you can use the wizard to create new 

policies using the FQDN for the WAN addresses.

Click Apply to save your settings. The IPSec VPN policy is now added to the List of VPN 
Policies table on the VPN Policies screen for IPv6. By default, the VPN policy is enabled.

Configure a VPN policy on the remote gateway that allows connection to the wireless VPN 
firewall.

Activate the IPSec VPN connection:

a. Select VPN > Connection Status. The Connection Status submenu tabs display with 

the IPSec VPN Connection Status screen in view:

What is the remote LAN IP 

Address?

Enter the LAN IPv6 address of the remote gateway.

The remote LAN IPv6 address needs to be different from the local 

LAN IPv6 address. For example, if the local LAN IPv6 address is FEC0::1, 
the remote LAN IPv6 address could be FEC0:1::1 but could not be 
FEC0::1. If this information is incorrect, the tunnel fails to connect. 

IPv6 Prefix Length

Enter the prefix length for the remote gateway.
