Do I need to set the custom dns to 208.67.222.222 and 208.67.220.220 or the WAN dns? If I set the WAN dns to the following mentioned above and specify my pc in the DNS filter to no filtering, I get blocked and cannot access certain sites. However, if I set it in the custom DNS it works fine. All PC's not set in DNS filtering are being block to certain sites. PC's set in DNS filtering set to no filtering works fine.
