To configure Azure Web Application Firewall policies for Front Door, define custom rules and managed rule sets, then associate the policy with your routing endpoint to inspect incoming traffic and enable bot protection.

Troubleshooting WAF rules on Application Gateway involves analyzing WAF logs in Log Analytics to identify false positives, then tuning managed rules or applying exclusions to allow legitimate traffic while maintaining protection.

You can deploy Azure WAF configurations using Bicep, ARM templates, or Terraform to automate policy creation, rule-set management, and association with Front Door or Application Gateway resources for consistent security patterns.

Geo-filtering in Azure WAF policies works by creating custom rules that match client IP addresses against geographic databases, allowing you to block or allow traffic from specific countries or regions before managed rules evaluate requests.

You need network access when configuring WAF policies because the system may fetch official Microsoft documentation via web fetching tools to reference current guidance on rule sets, bot protection, and deployment patterns during troubleshooting tasks.

Azure Front Door WAF logs may not appear in Log Analytics if diagnostic settings are not configured to send firewall logs to your workspace, or if the WAF policy is not correctly associated with the active Front Door endpoint.
