Configuring Azure Firewall Policies and Network Rule Collections

I configured Azure Firewall Network Rule Collections to control traffic flow between Azure resources.

The rules were built using the following parameters:

Source Type & Source: Defined trusted IP ranges and IP groups.

Protocol: Allowed specific traffic (ICMP for ping, TCP for web traffic, VPN access, etc.).

Destination Type & Destination: Set destinations to backend servers, VPN gateways, and IP groups.

Destination Ports: Restricted access to only necessary ports (80, 443, 8000–9000).

This setup ensures secure and controlled communication within the cloud environment, improving security and preventing unauthorized access.
