How Do I Plan CIDR Blocks for Access to a VPC Through a VPN Connection?
Updated on 2023-10-20 GMT+08:00
- The CIDR blocks of a VPC cannot conflict with on-premises CIDR blocks.
- To avoid conflicts with cloud service addresses, do not use 127.0.0.0/8, 169.254.0.0/16, 224.0.0.0/3, or 100.64.0.0/10 for your on-premises network.
