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.
- On the Main tab, click.The Virtual Server List screen opens.
- Click theCreatebutton.The New Virtual Server screen opens.
- In theNamefield, type a unique name for the virtual server.
- In theDestination Address/Maskfield, 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 is10.0.0.1or10.0.0.0/24, and an IPv6 address/prefix isffe1::0020/64or2001: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/32prefix.The IP address for this field needs to be on the same subnet as the external self-IP.
- In theService Portfield, type53.
- From theProtocollist, selectTCP.
- Optional: If you are using SNATs on your network, from theSource Address Translationlist, selectSNAT.
- Optional: From theSNAT poollist, select the name of an existing SNAT pool.
- From theConfigurationlist, selectAdvanced.
- From theDNS Profilelist, select the custom DNS profile you created.
- ClickFinished.
Create another virtual server with the
TCP protocol, but use an IPv6 address and configuration.
