To establish communication between GTM Systems (now referred to as BIG-IP DNS) and other BIG-IP Systems, specifically for the purposes of synchronization and iQuery communication, the following two ports must be enabled:
B. 53
Port 53 is used for DNS queries, which are fundamental to the operation of GTM systems. While GTM primarily uses this port for DNS resolution purposes, it's essential for the basic DNS functionality between these systems.
D. 4353
Port 4353 is specifically used for iQuery communication between BIG-IP systems. iQuery is a proprietary protocol used by F5 devices to exchange topology and status information among themselves, such as between GTM and LTM systems.
Ports like A. 22 (SSH) and C. 443 (HTTPS) are common for management access and secure web access, respectively, but are not specifically required for the operational communication between GTM and other BIG-IP systems in the context of synchronization and iQuery communication. E. 4354 is not standardly associated with BIG-IP system communications.
