Hi Community !


I NEED to set up an educational WLAN with a strict whitelist approach.
10 Rules are going to be sufficient, so I bought this router.


Some whitelist entries work, but others not....

www.tagesschau.de (german news site) -> access rule work as expected

www.udemy.com (educational training site) -> no access possible and I dont know why.

www.youtube.com no access possible, same here.


After investigating i tried to create a rule or the IP of www.udemy.com -> the rule works (I can acces the IP) BUT i get an error, because Udemy uses Cloudflare and direct IP access is prohibited.
Adding cloudflare does not solve this issue


Unmarking Checkbox "Enable internet Access Control" lets me access these sites with no problem...( and, or course, any other site...)


What am I missing?
(DNS: from my ISP and/ or 8.8.8.8)


Any meaningfull idea/Info/hint will be highly appreciated!


Best regards,

TBW
