HOWTO: How do I prevent my URL blacklist from being bypassed by browsing to the site IP address

Expand / Collapse
Show/Hide Article Tools


This article applies to:

  • SWG 10.0 and above

Question:

  • When we block a site (e.g. www.acme.com) the user can browse to the site IP (e.g. 1.1.1.1) and bypass our custom defined block list, how do I prevent this ?

Procedure:

  1. Make sure you have SWG 10.0 or above

  2. The Device IP Advanced tab allows administrators to enable the Reverse DNS lookup option, to determine the domain name that is associated with

    a given IP address (using DNS).

  3. Click Edit and check the Enable Reverse DNS box.

  4. Click Save, then Commit changes.
