What Are the Differences Between Private NAT Gateways and Public NAT Gateways?

Private NAT gateways perform NAT between private IP addresses and resolve the following problems:

  • Private IP address conflicts
  • Access from specified addresses

Public NAT gateways perform NAT between private IP addresses and public IP addresses and have the following advantages:

  • Secure: Only shared EIPs, instead of all EIPs of servers, are exposed to the Internet.
  • Cost-effective: EIPs and bandwidth are shared, saving network infrastructure costs.
