CreateVpcFirewallConfigure - Cloud Firewall - Alibaba Cloud Documentation Center

Creates a VPC firewall to protect traffic between two Virtual Private Clouds (VPCs) that are connected by an Express Connect circuit.

Operation description

This operation creates a VPC firewall. The VPC firewall protects traffic between two VPCs that are connected by an Express Connect circuit. This VPC firewall does not protect traffic between VPCs in different regions, between VPCs that belong to different accounts, or between a VPC and a Virtual Border Router (VBR). For more information, see Limits on VPC firewalls.
