Reference architecture

As there are many configuration possibilities, this guide presents several operations that you can perform on your firewall. Some of them work in all situations, while others work in an architecture that serves as an example in this guide. Use these examples by adapting them to your requirements.

Architecture presented

For this architecture, the configuration of the firewall must meet the following requirements:

  • Hosts connected to the "in" network must be able to access:
    • The "Internet" via DNS, HTTP and HTTPS. Their access must go through URL filtering.
    • The internal web server (protected by the firewall) via HTTPS.
  • The “Internet” must be able to reach the internal web server (protected by the firewall) via HTTPS.
