Introduction
Azure Firewall Rules are essential for securing your Azure resources. They define the rules for allowing and denying traffic.
Key Concepts
- Rules: Define what traffic is allowed or denied.
- Conditions: Specify criteria for evaluating rules (e.g., source/destination IP, port).
- Actions: Define the response to traffic matching a rule (e.g., allow, deny, log).
Example Rules
Here are some basic examples:
- Allow Azure VMs from a specific IP address: `Allow Azure VMs from 192.168.1.0/24`
- Block all traffic from a specific IP address: `Block from 10.0.0.0/8`
- Allow all traffic to a specific port: `Allow TCP 80`
Advanced Concepts
Understanding advanced features like Dynamic Routing and Policy Sets will greatly improve your security configuration.
