Find SonicWall Hidden Configuration Page
In this tutorial I will be showing you how find the SonicWall hidden configuration page. Well it’s hidden from most because there is no real easy way to access it from the GUI. In these simple steps I will show you how to access these amazing features.
Step 1: Log into your SonicWall.
Step 2: Replace the /main.html with /diag.html
Step 3: Click on the [ INTERNAL SETTINGS ] button to load the hidden features and configuration options.
Below are actually all the settings you can change under this features and configuration options page.
