Features

SNAT

Switch SNAT address to hidden private IP

The SNAT function provides agent service to access Internet to virtual machine instance without the Public IP in VPC.

Meanwhile, multiple intranet instances have access to the public network via one NAT Gateway Public IP to share the bandwidth.

Traffic Monitoring

Multi-dimension Monitoring

The monitoring page provides multi-dimensional data such as public network access in and out rate speed (bps), concurrent connections, created connections, NAT Gateway package loss number, source port exhaustion and packet loss number, facilitating users to monitoring NAT Gateway traffic health status in real time

Scenarios
