Enable UDP on Windows for Firewall Log Analyzer

Allowing inbound UDP traffic

Overview

RocketCyber's Firewall Log Analyzer is architected to eliminate the need of shipping hardware or deploying complex software. To facilitate the collection of firewall telemetry, UDP 514 is the recommended protocol/port. It is very common that the configuration of Windows Firewall has this blocked, therefore the Firewall Analyzer app has been designed to automatically add an inbound rule for the configured Port and Protocol to allow traffic in. If you are using another host based firewall you should consult the documentation on how to allow this traffic. If your just curious about manually configuring the rule, read on.
