What Do I Do If a VPN Connection Is Interrupted and a Message Indicating Data Flow Mismatch Is Displayed?
This is usually caused by an ACL mismatch between the VPN gateway on the cloud and the customer gateway in your on-premises data center.
- Verify that at the two ends of the VPN connection, the local and remote subnets are reversed and the ACL configurations are also reversed.
- Use the subnet/mask format when you configure interesting traffic in your on-premises data center. Do not use the address object mode since it may cause incompatibility issues.
