both Vulnerability Scan and Intrusion Prevention are disabled

Thanks for your support my Dear 🙂

If you are uncertain, http://urlquery.net can be helpful.

It will report on what happens when you go to a particular URL.
It can even give you a preview (sometimes) of the page.

Thank you @PSX_Defector for the ideas.
We don't use any VPN or any special configuration.
as i mentioned it is only for :
Limit the bandwidth of internet per IP address
Firewall/blocking- it is bit similar to Untangle firewall.
We will explore this stuff today while nobody is using in Production.
I am excited to learn.
of course will post some question pretty soon. 🙂
