Redirect All Traffic of LAN to Certain Website Using OpenWrt

Currently I am running OpenWRT in my router and I created an open access point for advertisement. So now whoever connect to my WIFI and browse any website I want them to get redirected to my website. I have tried iptables but could not avail to get success. It would be better if I can do that using LUci.

Have you tried WiFiDog?

Are you trying to create a Captive Portal?
