NAT Gateway provides different types of packages. Select the package that meets your needs.
Configuration Specifications
NAT Gateway supports binding up to 10 EIPs, and a maximum of 5 Gbps traffic surge and 10,000,000 concurrent connections, while providing three configuration specifications:
Small-scale (a maximum of 1000,000 connections)
Medium-scale (a maximum of 3000,000 connections)
Large-scale (a maximum of 10,000,000 connections)
Note:
Restricted by standard protocols, for the NAT gateways with the same protocol/destination IP/destination port, the number of maximum connections = the number of bound EIPs × 55000. To increase the number of connections, bind new EIPs or adjust the destination IP/port.
Maximum Public Network Outbound Bandwidth
Available maximum public network outbound bandwidths of the NAT gateway (in Mbps): 10, 20, 50, 100, 200, 500, 1,000, 2,000, and 5,000.
Maximum Public Network Inbound Bandwidth
The maximum public network inbound bandwidth of a NAT gateway is 5 Gbps by default, which is unchangeable for now.
The traffic cost of NAT Gateway is calculated based on the maximum public network outbound bandwidth regardless of the public network inbound bandwidth.
