Bypass DNS hijacking (Transparent DNS Proxy) with DNSMasq

So my ISP is blocking some site left and right, changing the DNS manually is not working due to Transparent DNS Proxy. The workaround is possible by installing DNSCrypt in my computer, however not every PC support DNSCrypt.

I was thinking to fix this problem on router level so every device under the router would be able to access every site without additional program like DNSCrypt.

Here's my settings :

However it's not working because when I check on dnsleaktest.net or ipleak.net, it's still using my ISP DNS.

Any idea why?
