个人拙见：home side $DISPLAY=:0  is consistent with the listening port of X-server Application.

Display NumberX11 server applications typically listen on TCP port 6000 by default, which is equivalent to “display number 0”. Some X11 server applications may be configured with a display number that is higher than zero. If the X11 server is configured as display 40, for example, it means the X11 server application is listening on port 6040; you would need to configure SecureCRT’s Display value to reflect 127.0.0.1:40.0.
