What Do I Do If a VPN Connection In Use Is Interrupted and a Message Is Displayed Indicating That Traffic from IP Addresses Not Whitelisted Generates?
This is usually caused by ACL mismatch between the local and remote gateways.
- Check whether the local and remote subnets of the VPN connection are matched pairs. Ensure that ACL rules at both ends of the VPN connection do not conflict each other.
- 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.
