 The client has the same offset logic. The users configures the main port (default 8848) as in the use of 1.X, and calculates the corresponding gRPC port (default 9848) through the same offset.
 
 Therefore, if there is a port forwarding or firewall between the client and the server, the port forwarding configuration and firewall configuration need to be adjusted accordingly.

 客户端拥有相同的计算逻辑，用户如同1.X的使用方式，配置主端口(默认8848)，通过相同的偏移量，计算对应gRPC端口(默认9848)。
 
 因此如果客户端和服务端之前存在端口转发，或防火墙时，需要对端口转发配置和防火墙配置做相应的调整。
