DHCPv6 Server Options
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.
Stateless DHCPv6 Server
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 Configure the IPv6 Router Advertisement Daemon and
Advertisement Prefixes for the LAN on page 88
.
Stateless DHCPv6 Server with Prefix Delegation
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:
1. The VPN firewall’s DHCPv6 client requests prefix delegation from
the ISP.
You must select the Pref
ix Delegation check box on the ISP Broadband Settings screen
for IPv6. For more information, see Use a DHCPv6 Server to Configure an IPv6 Internet
Connection on p
age 40.
2. The ISP allocates a prefix to the VPN firewall.
T
his prefix is automatically added to the
List of Prefixes to Advertise table on the LAN
RADVD screen for IPv6. For more information, see Configure the IPv6 Router
Advertisement Daemon and Advertisement Prefixes for the LAN on p
age 88.
3. 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 pre
fixes:
• The prefix that was added through prefix delegation
• Prefixes that you manually added to the List of Prefixes to Advert
ise table on the
RADVD screen
You then perform the following tasks:
• Select the Prefix Del
egation check box on the LAN Setup screen for IPv6.
