GTM iRule - answering DNS based on some criteria.

Hi Brad,

I have now developed this:

when DNS_REQUEST {
  if { [IP::addr [IP::remote_addr] equals $::All_Client_IPs] } {
      if {[LB::status vs Client_VPN_1] eq "up" } {     
        host 1.1.1.1
      } else {
        host 2.2.2.2
    }
  }
}

but it doesn't work. Looks like is not possible to use data groups from the GSLB level.

I have successfully tested this instead:

when DNS_REQUEST {
  if { [IP::addr [IP::remote_addr] equals 10.10.10.10] } {
      if {[LB::status vs Client_VPN_1] eq "up" } {     
        host 1.1.1.1
      } else {
        host 2.2.2.2
    }
  }
}

it's ok, but bit painful to use multiple "or" statements for multiple network ranges/IPs

Is there any workaround for that?

Many thanks

Mariusz
