I'm trying to "filter" explicit URLs (+18/21) from network traffic and redirect to another website. I have physical access to router inside my home, computer and router local web-access, which let's say does not support Captive portal and is not DD-WRT supported. My router is also not Cisco just to note.
Is there any other way I can filter URLs, but make sure that user is redirected to another website and not just have blocked access (by router settings). So what I'm actually trying to achieve is to make wireless user be redirected on every particular URL to constant pre-defined URL. I though maybe about OS firewalls or URL blockers but I don't know which software has a wireless URL redirection options.
Here is the basic graph-image of network configuration I have to implement:
Any advices are appreciated. Thanks and regards everyone!
