Should port 443 and 22 openfor communication between GTM and LTM. If yes then for what process it is used specifically.

we performed penetration testing on our F5 devices and found that port 443 and 22 are open on the production traffic interfaces. when checked found that the LTM devices are added on the GTM using the IP addresses of the production interfaces.

 

As port 443 and 22 opened on LTM production interfaces raises an operational risk we need to block these ports. but before we go ahead wanted to confirm if 443 and 22 required for any communication in between the F5 devices.
