RTSP and related_server rule

Can anyone explain how "relate_server" works?

 

Does it accept array as input type for client_port and server_port?

 

I need to create a related connection for all ports in udp flow.

 

And why relate_server command doesn't see local variables of RTSP_RESPONSE scope?

 

Does any alternative way to get all my setup working exist?
