Hi folks, I found similar posts, but not this specific issue - apologies if this has been asked/answered already:
Scenario: I wanted to block "instagram.com" at it's a major distraction for the kids doing homework (they don't have phones, but they do have access to the internet via the 2 laptops I make available for homework).
I've installed and configured OpenDNS - seems to be working great in general (I used the FamilyFriendly DNS servers on my router so porn is automatically filtered out before I have to lift a finger).
I then set up a free account, installed the IP updater on our home PC, enabled the OpenDNS setting to allow it to update (as we have a dynamic IP address).
Finally, I went to OpenDNS > Dashboard > Settings > Web Content Filtering and selected "Moderate" filtering level and added "instagram.com" as an "Always Blocked" domain. I also set up a custom block page message with a picture of me and a message that says, "Do your homework, chumps."
Here's the problem: the site is successfully blocked, but the OpenDNS block page doesn't always come up. Attached are 3 screenshots: trying to go to instagram.com from Internet Explorer, Firefox and Chrome. Notice that Internet Explorer is the only one that makes it to the block page.
Admittedly, this is a minor issue: the main purpose has been accomplished - instagram is successfully blocked. But why aren't they seeing the block pages in Chrome or Firefox (they mostly use Chrome as one of our machines is a chromebook)?
