Basic controller and site communication

To add a DNS policy, you must also define the DNS real server and VIP on the ServerIron ADX as 
shown in the following example.

 !

 server real <dns-rs-name> <dns-ip-addr>

  port dns

  port dns zone "<domain-name>"

  port dns proxy

  port http

  port http url "HEAD /"

 !

 !

 server virtual <dns-vs-name> <vip-ip-addr>

  port dns

  port http

  bind dns dns-rs dns

  bind http dns-rs http

 !  

 gslb dns zone <domain-name>

  host-info www http

Use server real <dns-rs-name> <dns-ip-addr> for a local DNS server. Use server remote-name 
<dns-rs-name> <dns-ip-addr> for a remote DNS server. The host-info defines an enabled 
application in the DNS zone. For example, you can also specify host-info ftp ftp.
