Firewall Rule Workbench

Read a real business requirement, build the firewall rule that satisfies it, then verify it against captured traffic

Common Ports Quick Reference

How This Workbench Works

Each work order states a real business requirement in plain language. You are the network technician: pick the transport protocol (TCP or UDP), type the port number, and choose the service from the list. Click Test Rule. A rule that does not match what the requirement actually needs has a real consequence explained in the feedback. Once your rule is correct, a live traffic capture appears. Click every packet that your deployed rule would actually let through, based on the exact protocol and port you configured, then click Confirm Traffic Match. Get the whole set right to close the work order and move to the next one.
