I tested the rule on Firefox within Ubuntu VM and it worked as it gave me a forbidden error code page. When I tested it on my phone browser, it does not work as it just shows the index page with no errors. Is there a different configuration I needed to do for it or it just does not work on a mobile phone browser?
The URL I used is, "HTTP://vhost1.group21.com/?ID=103.50.84.114".
