Hello eneR
"An iQuery connection is defined as an SSL connection on port 4353 from a local gtmd process to the big3d process on a remote or local BIG-IP server. When big3d starts, it listens for port 4353 on all configured self IP addresses and the management interface IP address."

I recommend you to use always the TMM instead of Mgmt interface.
