Hi Gapexx, I created a Listener and notice GTM creates a port 53 virtual server. Looking at that virtual server more closely, I see an option for "Source". The help page mentions:

 

Specifies an IP address or network from which the virtual server will accept traffic. For this setting to work, you must specify a value other than 0.0.0.0/0 or ::/0 (that is, any/0, any6/0). In order to maximize utility of this setting, specify the most specific address prefixes covering all customer addresses and no others.

 

Is this something you can test?

 

Kevin

    I can try to test this in ma lab, but this will also limit traffic to dns express part whiich has to be available to everyone, since f5 is authoritative for those zones
