Configure RDNS Servers and DNS Search List for IPv6 Router Advertisements

Perform this task to configure IPv6 Router Advertisements for DNS Configuration of IPv6 hosts.
  1. Enable the firewall to send IPv6 Router Advertisements from an interface.
    1. Select
      Network
      Interfaces
      and
      Ethernet
      or
      VLAN
      .
    2. Select the interface to configure.
    3. On the
      IPv6
      tab, select
      Enable IPv6 on the interface
      .
    4. On the
      Router Advertisement
      tab, select
      Enable Router Advertisement
      .
    5. Click
      OK
      .
  2. Specify the Recursive DNS Server addresses and DNS Search List the firewall will advertise in ND Router Advertisements from this interface.
    The RDNS servers and DNS Search List are part of the DNS configuration for the DNS client so that the client can resolve IPv6 DNS requests.
    1. Select
      Network
      Interfaces
      and
      Ethernet
      or
      VLAN
      .
    2. Select the interface you are configuring.
    3. Select
      IPv6
      DNS Support
      .
    4. Include DNS information in Router Advertisement
      to enable the firewall to send IPv6 DNS information.
    5. For DNS
      Server
      ,
      Add
      the IPv6 address of a Recursive DNS Server.
      Add
      up to eight Recursive DNS servers. The firewall sends server addresses in an ICMPv6 Router Advertisement in order from top to bottom.
    6. Specify the
      Lifetime
      in seconds, which is the maximum length of time the client can use the specific RDNS Server to resolve domain names.
      • The
        Lifetime
        range is any value equal to or between the
        Max Interval
        (that you configured on the
        Router Advertisement
        tab) and two times that
        Max Interval
        . For example, if your Max Interval is 600 seconds, the Lifetime range is 600-1,200 seconds.
      • The default
        Lifetime
        is 1,200 seconds.
    7. For DNS Suffix,
      Add
      a
      DNS Suffix
      (domain name of a maximum of 255 bytes).
      Add
      up to eight DNS suffixes. The firewall sends suffixes in an ICMPv6 Router Advertisement in order from top to bottom.
    8. Specify the
      Lifetime
      in seconds, which is the maximum length of time the client can use the suffix. The Lifetime has the same range and default value as the
      Server
      .
