Q: What is the requirement of the network lock for cross-network segment? How to solve that there is a cross-network user and he can’t access?

A: (1) The driver is not installed, and it can be found under Support in installation directory of running version. (2) The lock service is not started. The lock services are Sentinel Keys Server and Sentinel Protection Server (3) The port is occupied. And what we're actually going to use is 6001, 6002, 7001, 7002 (4) Firewall. Whether the UDP\TCP port has a problem, resulting in the service request blocked. And then you look at the bottom and see what happens.
