Hello,

Could you please clarify the source and destination for this communication? do you mean the mgmt IP of F5 is communicating with one of the back end server or what do you mean by the vip (is it virtual server on the same F5)?

and where do you see this traffic from? becaused based on your post, the mgmt IP is communicating with vip (which is the virtual server configured on F5)

Thanks to clarify to discuss the behavior further.

Dear Mohamed_Salah_

yes, mgmt IP of F5 is communicating with virtual server ip (is it virtual server on the same F5 - public IP).

and where do you see this traffic from?

source : F5 mgmt IP

Destination: virtual server public ip

Destination port : 0
