Use a DHCPv6 Server to Configure an IPv6 Internet
Connection
The wireless VPN firewall can autoconfigure its ISP settings through a DHCPv6 server by
using either stateless or stateful address autoconfiguration:
• S
tateless address autoconfiguration. The wireless 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 ident
ifies the subnet that is associated with
the WAN 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 wireless 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
