Enterprise Edition anti-virus software and a relatively complete desktop management system, coupled with a constantly strict network usage management system, which has left the second place for security issues; in addition, my organization does not have an OA license).

You can use this method for testing and application, and finally come up with a real solution.
Many of my friends have encountered this problem and have worked hard to crack
If the reverse proxy software is used, the http://192.168.1.110:2046/URL is reversed to the http://www.xxx.com/URL, with REQUEST.GETREMOTEADDR () Method gets the IP address: 127.0.0.1 or 192.168.1.110, not the real IP of the client.
