For IPv6 WAN connections, this router can have a static IPv6 address or receive
connection information when configured as a DHCPv6 client. In the case where the
ISP assigns you a fixed address to access the internet, the static configuration
settings must be completed. In addition to the IPv6 address assigned to your router,
the IPv6 prefix length defined by the ISP is needed. The default IPv6 Gateway
address is the server at the ISP that this router will co nnect to for accessing the
internet. The primary and secondary DNS servers on the ISP‘s IPv6 network are
used for resolving internet addresses, and these are provided along with the static IP
address and prefix length from the ISP.
When the ISP allows you to obtain the WAN IP settings via DHCP, you need to
provide details for the DHCPv6 client configuration. The DHCPv6 client on the
gateway can be either stateless or stateful. If a stateful client is selected the gateway
will connect to the ISP‘s DHCPv6 server for a leased address. For stateless DHCP
there need not be a DHCPv6 server available at the ISP, rather ICMPv6 discover
messages will originate from this gateway and will be used for auto configuration. A
third option to specify the IP address and pre fix length of a preferred DHCPv6
server is available as well.
