Dear All,

I've figured out what'= ;s causing it: DNSCrypt! How do I get rid of this!

If you really want to hand out dns server address 'direct' to your<= br> clients and avoid all the caching/resolving goodness of dnsmasq then
take a look at
http://www.thekelleys.org.uk/dnsmasq/docs= /dnsmasq-man.html and the
'--dhcp-option' defaults.=C2=A0 They can be overridden, indeed you = can
specify 'dhcp-options' via the luci gui (network-interfaces-lan-dhc= p

Hopefully that helps.
