Endian Firewall is an Open Source Unified Threat Management (UTM) appliance software. This document is a concise reference to the Endian Firewall web interface.
To access the Endian Firewall GUI is as simple as starting your browser and entering the IP address of the internal (GREEN) interface or the hostname of your Endian Firewall.
Your browser will be redirected to a secure HTTPS connection (port 10443). Since Endian Firewall uses a self-signed HTTPS certificate, your browser might ask you to accept the certificate at first connection time. The system will then ask for username and password. Specify "admin" as the username and provide the password you set up during installation or, if you bought an appliance, the one you got from your reseller.
You should now be looking at the start page of your Endian Firewall GUI. You can immediately start exploring the different options and the information available to you through this interface. The rest of this guide follows the layout of the main navigation bar - each chapter corresponds to a main navigation item.
