Creating virtual servers to forward zone transfer requests

Determine to which DNS server you want the virtual servers to forward DNS zone transfer requests.
Create virtual servers to alert the BIG-IP system to zone transfer requests destined for a DNS server that hosts the zone. Create two virtual servers that use the TCP protocol, one each for an IPv4 address and IPv6 address.
DNS zone transfers use port
53
.
This task applies only to LTM-provisioned systems.
  1. On the Main tab, click
    Local Traffic
    Virtual Servers
    .
    The Virtual Server List screen opens.
  2. Click
    Create
    .
    The New Virtual Server screen opens.
  3. In the
    Name
    field, type a unique name for the virtual server.
  4. In the
    Destination Address
    field, type the IP address in CIDR format.
    The supported format is address/prefix, where the prefix length is in bits. For example, an IPv4 address/prefix is
    10.0.0.1
    or
    10.0.0.0/24
    , and an IPv6 address/prefix is
    ffe1::0020/64
    or
    2001:ed8:77b5:2:10:10:100:42/64
    . When you use an IPv4 address without specifying a prefix, the BIG-IP system automatically uses a
    /32
    prefix.
    The IP address for this field needs to be on the same subnet as the external self-IP.
  5. In the
    Service Port
    field, type
    53
    .
  6. From the
    Protocol
    list, select
    TCP
    .
  7. Optional: If you are using SNATs on your network, from the
    Source Address Translation
    list, select
    SNAT
    .
  8. Optional: From the
    SNAT pool
    list, select the name of an existing SNAT pool.
  9. From the
    Configuration
    list, select
    Advanced
    .
  10. From the
    DNS Profile
    list, select the custom DNS profile you created.
  11. Click
    Finished
    .
Create another virtual server with the TCP protocol, but use an IPv6 address and configuration.
