  1. Deployment: Deploy Palo Alto firewalls in active/passive mode in each target AWS region behind the ALB.
  2. Interfaces: Configure the firewall interfaces to connect to the internal network and the ALB.
  3. Security Policies: Create security policies allowing desired traffic and blocking malicious traffic.
  4. Virtual Router: Configure a virtual router for routing traffic within the network.
  5. Default Route: Set a default route pointing towards the ALB’s internal IP address.

Important Considerations:

  • Health Checks: Configure health checks for Palo Alto firewalls so GWLB can accurately monitor the firewall’s status.
  • Scaling: Design your deployment for auto-scaling in line with your traffic demands.
  • IP Addresses: Ensure clear allocation and segregation of IP addresses for firewalls, ALBs, and backend resources.
