Netgear FVS318Gv2 – ProSAFE VPN Firewall Series Reference Manual

The IPv6 clients in the LAN can autoconfigure their own IPv6 address or obtain an IPv6 
address through a DHCPv6 server. For the LAN, three DHCPv6 options are available.

The IPv6 clients in the LAN generate their own IP address by using a combination of locally 
available information and router advertisements but receive DNS server information from the 
DHCPv6 server. For stateless DHCPv6, you must configure the RADVD and advertisement 
prefixes. For more information, see 

on page 88. 

As an option for a stateless DHCPv6 server, you can enable prefix delegation. The ISP’s 

stateful DHCPv6 server assigns a prefix that is used by the VPN firewall’s stateless DHCPv6 

server to assign to its IPv6 LAN clients. 

Prefix delegation functions in the following way:

The VPN firewall’s DHCPv6 client requests prefix delegation from the ISP.

You must select the Prefix Delegation check box on the ISP Broadband Settings screen 
for IPv6. For more information, see 

on page 40.

The ISP allocates a prefix to the VPN firewall.

This prefix is automatically added to the List of Prefixes to Advertise table on the LAN 
RADVD screen for IPv6. For more information, see 

on page 88.

The stateless DHCPv6 server allocates the prefix to the IPv6 LAN clients through the 

RADVD. 

When prefix delegation is enabled, the RADVD advertises the following prefixes:

The prefix that was added through prefix delegation

Prefixes that you manually added to the List of Prefixes to Advertise table on the 
RADVD screen

You then perform the following tasks:

Select the Prefix Delegation check box on the LAN Setup screen for IPv6.
