Webfilter Block Page

I have a Route10 set with some blocked applications and sites. Is there a way to have a page display saying it has been blocked by the Route10, rather than just going to the browser “can not be reached” page?

Synology offers this feature

It’s not something that we offer currently, but it’s also not a top priority because technology has changed, making this feature less useful in today’s browser landscape than it used to be.

Because most browsers default to HTTPS-first nowadays, you will end up with a security warning instead of a nice blocked page like you expect.

Thanks for the conformation and clarification Jeff.
