I want my some specific customers(Those who didn’t paid their bill on time), I want to show them a pop up notice or anything like notice and also block their Internet.
Those customers will see the notice while browsing anything on any device. They won’t be able to use Internet and will see only the notice.
Is there any way to redirect to the notice?
My customers are connected via PPPoE
Their Local IP Block is: 10.50.0.0/22
RouterBoard v6.42.6
Sorry for my bad English.
Thanks for any kind of help.
Since https became ubiquitous, there is no way to redirect user browsing to your warning page any more without the user getting an “insecure site” warning from the browser. You can send a notification e-mail and block access to anywhere but your own site - if they lose internet access, they’ll call the hotline to ask what is wrong. The only ways to warn them before actually disconnecting them is to send e-mails and to slow down connections.
You can redirect to the notice, but it has to be http, not https. Browsers have a relatively new feature called “captive portal detection” which is meant to detect if you have such a redirection for http and send the user to the page. They should not get an insecure site warning as long as you aren’t redirecting them to an HTTPS page.
The only potential issue with this captive portal detection is if the user is already using the service just before it gets cut off, the detection may not re-run and then the user would just see errors. But then if they either restart their router or computer or browser, the detection should then re-run and they would get sent to the captive portal.
