Sorry, I am new in F5. My service provider setup F5 based on my requirement. Based on their feedback, none of the configuration will make F5 to initiate dns traffic to that 173.245.58.100. Based on the design, we have 2 F5 GTM devices installed (one for each site / location having their own internet access; both site are interconnected with our WAN connection - not thru internet). GTM should only answer internet dns query for our company domain. And our internal dns server has ip 10...*.

 

How can we trouble shoot such connection problem? In additional, can we configure both GTM to sync via management port which is on our local WAN connected lan in stead of going thru the default data port with route thru firewall and internet?
