VPC Border Firewall Overview
Updated on 2024-11-04 GMT+08:00
The VPC border firewall supports access control for communication traffic between VPCs, visualizing and protecting internal service access.
Constraints
- Only the professional edition supports VPC border firewalls.
- Only VPCs in the enterprise project to which the current account belongs can be protected.
- To use public network CIDR blocks other than 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, and 100.64.0.0/10 as private network CIDR blocks, submit a service ticket, or CFW may fail to forward traffic between your VPCs.
Configuration Process
The following figure shows the configuration process in VPC mode.
