Securing GTM iQuery port 4353

F5 GTM uses TCP 4353 for iQuery between two GTM across the Data Center. Is there a way to secure this communication either by using encrypted iQuery OR can we configure the policy in GTM to restrict the communication between these two GTM only.

 

Remember our GTM interface is directly connected to the internet.

    iQuery is already encrypted. As for ACL, this is better suited for the AFM add-on license which then allows you to place an L3/L4 firewall policy in the management interface as well as the self IPs.
