Use a DHCPv6 Server to Configure an IPv6 Internet
Connection
The VPN firewall can autoconfigure its ISP settings through a DHCPv6 server by using either
stateless or stateful address autoconfiguration:
• S
tateless address autoconfiguration. The VPN firewall generates its own IP address
by using a combination of locally available information and router advertisements, but
receives DNS server information from a DHCPv6 server.
Router advertisements include a prefix that identifies the subnet that is associated with
the W
AN port. The IP address is formed by combining this prefix and the MAC address of
the WAN port. The IP address is a dynamic address.
As an option for stateless address autoconfiguration, the ISP’s st
ateful DHCPv6 server
can assign a prefix through prefix delegation. The VPN firewall’s own stateless DHCPv6
server can assign this prefix to its IPv6 LAN clients. For more information about prefix
delegation, see Stateless DHCPv6 Server With Prefix Delegation on p
age 98.
• S
tateful address autoconfiguration. The VPN firewall obtains an interface address,
configuration information such as DNS server information, and other parameters from a
DHCPv6 server. The IP address is a dynamic address.
To automatically configure a WAN interface for an IPv6 connection to the Internet:
1. Select Netwo
rk Configuration > WAN Settings > WAN Setup.
2. In
the upper right of the screen, select the IPv6 radio button. The WAN Setup screen
displays the IPv6 settings:
