URL blocking in OpenWRT?
<p>I have Asus RT-N16 router. Stock latest firmware has DualWAN settings, but it works definitely bad - some days (when ISP1 is not stable and dualwan operating?) when I open websites router frequently redirects me to 192.168.1.1. I checked 2 devices, both works same way.
One day I decided to change firmware, I read that OpenWRT is powerful, stable, etc. 
So I installed new firmware, latest Chaos Calmer 15.05. Then installed mwan3 package for multiwan features. Works stable, ok. 
But I did not found a simplest feature, that even stock firmware have, in admin panel - URL website filter. After googling I found some posts with crazy solutions, like manually (console) setting ip routes/hosts for every url or installing cache servers.
Is there a simple solution/package for URL/keyword domain blocking (parental control) for OpenWRT or do I need to search another firmware?</p>
