GTM Split DNS - Topology Records or Zone Views?

Hi,

you can assign this irule to the wide IP.

when DNS_REQUEST {
  if { [IP::addr [IP::remote_addr] equals 10.0.0.0/8] \
     or [IP::addr [IP::remote_addr] equals 192.168.0.0/16] \
     or [IP::addr [IP::remote_addr] equals 172.16.0.0/12] } {
    pool [string map {"_nat" "_int"} [lindex [pools -list] 0]]
  }
}

With this irule, pool name must be :

• pool1_nat with VS with external IPs
• pool1_int with VS with internal IPs

The pool pool1_nat must be assigned to the VS.

VS with external IPs must be created manually with following parameters:

• IP address : External IP address
• NAT address : LTM virtual server IP address (used to monitor service)
