Netgear FVS318N – Prosafe Wireless N VPN Firewall 参照マニュアル

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 wireless VPN firewall’s stateless 
DHCPv6 server to assign to its IPv6 LAN clients. 

Prefix delegation functions in the following way:

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

You need to select the Prefix Delegation check box on the ISP Broadband Settings 
screen for IPv6 (see 

The ISP allocates a prefix to the wireless VPN firewall.

This prefix is automatically added to the List of Prefixes to Advertise table on the LAN 
RADVD screen for IPv6 (see 

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 need to perform the following tasks:

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

Optionally, manually add prefixes to the List of Prefixes for Prefix Delegation table on 
the LAN Setup screen for IPv6 (see 

Optionally, manually add prefixes to List of Prefixes to Advertise table on the RADVD 
screen (see 

83).

The IPv6 clients in the LAN obtain an interface IP address, configuration information such as 
DNS server information, and other parameters from the DHCPv6 server. The IP address is a 
dynamic address. For stateful DHCPv6, you need to configure IPv6 address pools (see 

78).
