PLEASE NOTE: Web Filter > Blacklist settings are global and will impact everyone.
This is where you can block access to a website or App.
Note however that this feature is not always as easy as blocking a domain name. Many websites today will use two domain names: 1) the one we use in the browser, and 2) a completely different domain name they use to load-balance incoming traffic.
Example 1: How to block Twitter – blocking the website should block the app:
- Enter domain name twitter.com
- Save Filters
In about 15 minutes the website / app will stop working.
Example 2: How to block www.cars.com
- Fire up ping on your PC (how-to)
- Ping cars.com = cars.com
- Ping www.cars.com = e2457.e12.akamaiedge.net
- Enter both domain names into the Blacklist > domain field
- Save Filters
Troubleshooting (the website / app will not block):
- Make sure you have entered just the domain name, and not the full URL (see image above for good & bad entries)
- Reboot the device you are testing from to clear local caches (at least 15 after you created the block)
- Test from multiple devices
- Open a ticket and we’ll research why it will not block
NOTE: When blocking websites / apps via the Blacklist there is sometimes up to 15 min delay.
Example 2: How to block the game Fortnite – this cannot be done using normal tools, so use Schedule Internet Access
Fortnite is made my epicgames.com, and they are an Asian company that has built their system to be virtually un-blockable. Like Tor it uses hundreds of servers that are constantly changing and it works over ports 443 and 80 (which cannot be blocked).
Fortnite is not a normal website though, and most sites / apps can be blocked by enter the domain name above.
Can fortnite be blocked at all? Yes, using layer 7 filtering which is an advanced, resource intensive (i.e. expensive) method that requires server grade hardware. Which begs the question – if you can know they are playing (Web Usage Monitor) and block it by turning the Internet off (Schedule Internet Access), is the added cost and complexity worth it?
NOTE: Again, blocking a website / app works, but it takes a few minutes to take affect. Same with unblocking so, if you are looking for immediate results we recommend using Web Usage to see what they are doing, and then either verbally reprimand, or use Schedule Internet Access to enforce rules.
