01What the page shows
It is the default answer from Warda 0.8.4 (Network → DNS services → Answer to a blocked name). On the device the site was blocked for, the page gives the category, what decided and the device; another device sees the site and the time, never the reason. The ads and trackers of a page get an empty answer: the rest of the page looks as before. Apps that are not browsers simply fail.
02The security warning
On a secure site (https), the browser first warns that the connection is not private: the page comes from your Warda box, not from the site. Install the certificate of your Warda once on each device: open http://warda/certificate (or the link at the bottom of the block page), which gives the files and the steps.
- Windows: open the .crt file, Install Certificate, in Trusted Root Certification Authorities, then restart the browser.
- iPhone and iPad: in Safari, install the profile, then turn on full trust in Settings → General → About → Certificate Trust Settings.
- Mac: open the profile, then install it in System Settings.
- Android: in Settings, search for "CA certificate" and choose the file.
- Linux and Firefox (which keeps its own certificates): the steps of the page.
03Before you install it
Check that the fingerprint shown by the page is the one your device shows. The device then trusts the certificates your box makes: Warda makes them only for its block page, and its key never leaves the box. Install it only on your own devices, and again when the box is replaced or restored.
Limits: the page needs Warda on the ports 80 and 443; without the certificate some large sites show a warning with no way past it; a browser with its own secure DNS never asks Warda.
