AWS Network Firewall


We have created 3 subnets ( public, DB & APP) in each 3 Availability Zone in Single VPC and environment running Kubernetes environment in EC2 Instance. We have created a firewall endpoint in each availability zone. We have planned all traffic between the subnets to go through firewall . We have created the route table for flowing the traffic between the subnet.

We are facing issue , able get communication between with 1 & 2 AZ , in 3 AZ we are unable to do the communication. if we change the route table we are able get communication 2 & 3 AZ, but unable get communication to 1 AZ
