I just installed LEDE onto my Asus RT-N16.
DNS is causing me issues. It will not stop using the DNS provided by my ISP, which is a problem because my ISP blocks some sites redirecting them to an ISP block page.
I'm not sure whether I've hit a bug in my firmware or whether i missed something. I entered my DNS via the webui Network-->dhcp and DNS section of the webui.
I went to my WAN interface (which is PPOE to a modem) and checked the box to ignore the DNS provided by it.
And i went to the LAN interface and entered the custom DNS
I even tried ssh-ing in and adding nameservers to /etc/resolve.conf
EDIT: Turns out i missed entering the custom dns on the LAN interface. Maybe i forgot to save it. Thanks anyway guys
