The NAT Gateway provides a variety of packages for you to choose from.
Configuration Type
The NAT Gateway supports binding 10 EIPs and provides three configuration types, which can meet the maximum burst traffic of 5 Gbps and 10 million concurrent connections:
- Small (up to 1 million connections)
- Medium (up to 3 million connections)
- Large (up to 10 million connections)
Note:
Due to standard protocol restrictions, for the same protocol, destination IP, destination port, the upper limit of the number of connections = number of bound EIPs x 55,000. To increase the number of connections, please add a new bound EIP or adjust the destination IP/port, destination IP/port.
Maximum Public Network Outbound Bandwidth
The optional values of the maximum public network bandwidth of the NAT Gateway (unit: Mbps) are 10, 20, 50, 100, 200, 500, 1,000, 2,000, and 5,000.
Maximum Public Network Inbound Bandwidth
- The default maximum public network inbound bandwidth of the NAT Gateway is 5 Gbps, and setting a limit is not currently supported.
- The NAT Gateway traffic fee is calculated based on the maximum outbound bandwidth of the public network. The inbound bandwidth value of the public network has nothing to do with the fee.
