Client IP Pass-through

When a client of a DCS Redis 4.0 or later instance connects to the server through a VPC endpoint, the source IP address displayed on the server belongs to the VPC endpoint (starting with 198.19), and it is not the real client IP address. If client IP pass-through is enabled, the real IP address and port number of the client will be sent to Redis Server so that it can obtain the real IP address when running the client list, monitor, or slowlog get command. Client IP pass-through is disabled for all DCS Redis instances by default.
