  Read proxy.conf.  There are multiple options for load balancing.

  If you do round-robin, then yes, the packets go to random destinations.

  If you do keyed load balancing, then you can key off of User-Name / MAC address, etc.  And make all packets for the same user go to the same destination.

  This is all documented.
