Netgear FVS318Gv2 – ProSAFE VPN Firewall Series Reference Manual

By default, the VPN firewall supports IPv4 only. To use IPv6, you must enable the VPN 
firewall to support both devices with IPv4 addresses and devices with IPv6 addresses. The 
routing mode does not include an IPv6-only option; however, you can still configure a native 
IPv6 network if your ISP supports IPv6. These are the options:

IPv4-only mode. The VPN firewall communicates only with devices that use IPv4 
addresses.

IPv4/IPv6 mode. The VPN firewall communicates with both devices that use IPv4 
addresses and devices that use IPv6 addresses.

IPv6 always functions in classical routing mode between the WAN interface and the LAN 
interfaces; NAT does not apply to IPv6.
