FortiGate as an IPv6 DDNS client for generic DDNS

When configuring the generic DDNS service provider as a DDNS server, the server type and address type can be set to IPv6. This allows the FortiGate to connect to an IPv6 DDNS server and provide the FortiGate's IPv6 interface address for updates.

config system ddns
    edit <name>
        set ddns-server genericDDNS
        set server-type {ipv4 | ipv6}
        set ddns-server-addr <address>
        set addr-type ipv6 {ipv4 | ipv6}
        set monitor-interface <port>
    next
end

To configure an IPv6 DDNS client with generic DDNS:

config system ddns
    edit 1
        set ddns-server genericDDNS
        set server-type ipv6
        set ddns-server-addr "2004:16:16:16::2" "16.16.16.2" "ddns.genericddns.com"
        set ddns-domain "test.com"
        set addr-type ipv6
        set monitor-interface "port3"
    next
end
