TCP::remote_port
       Returns the remote TCP port number of a connection.

SYNOPSIS
       TCP::remote_port (clientside | serverside)?

DESCRIPTION
       Returns the remote TCP port/service number of a TCP connection. This
       command is equivalent to the BIG-IP 4.X variable remote_port. When used
       in a clientside context, this command returns the client-side TCP
       source port, and is equivalent to the TCP::client_port command.	When
       used in a serverside context, this command returns the server-side TCP
       destination port, and is equivalent to the TCP::server_port command.
