   The X11Forwarding option transfers TCP port 6000 traffic from one end   
   of the ssh connection to the other. On the OP's system A, he needs an   
   X server that listens on TCP port 6000 to accept that forwarded traffic.   
   (X11Forwarding is helpful when your X server only accepts TCP connections   
   from localhost.localnet, and unnecessary if your X server accepts TCP   
   connections from other network addresses).   
      
   However, from the ss(1) dump the OP provided, the OP's X server (vncserver)   
   does not appear to accept traffic on port 6000, and only has open the   
   VNC protocol ports necessary to converse in VNC protocol with the vncviewer.   
      
   This implies that the vncserver X server /does not/ use TCP to converse   
   with X clients, but instead uses the X "Local" support (shared memory,   
   unix socket, etc). So, nothing is listening for the traffic made   
   "local" to localhost.localnet by ssh X11Forwarding.   
      
      
   At least, that's how it appears to me. Agreed that the OP's problem   
   is moderately complex, and I may have missed something or misunderstood   
   the configuration or problem.
