Wireless Controller
User Manual
IPv6 prefix length defined by the ISP is needed. The default IPv6 Gateway address is
the server at the ISP that this controller will connect 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 Option 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 prefix length of a preferred DHCPv6 server
is available as well.
