I've recently installed LEDE 17.01.4 on my TP-Link TL-WR841N v12.
It seems to be working good, but I'm having some struggles with (Open)DNS.
It appears to think that dumpert.nl (a Dutch meme site) is a phising website.
This is nonsense, and even so, I still want access to it.
I tried changing /etc/config/dhcp by adding
list server '220.127.116.11'
list server '18.104.22.168'
to use Google's DNS servers instead of OpenDNS, and afterwards restarting with /etc/init.d/dnsmasq restart.
This however gives me
udhcpc: started, v1.25.1
udhcpc: sending discover
udhcpc: no lease, failing
which appears to be caused by the -n command line argument.
If i try /etc/init.d/dnsmasq restart with the -n removed, it will just keep udhcpc: sending discover.
I've also tried a reboot with these setting but with no avail.
TL;DR; How to unblock OpenDNS block?
