After starting dnscrypt-proxy, you will need to point your
|
|
local DNS server to 127.0.0.1. You can do this by going to
|
|
System Preferences > "Network" and clicking the "Advanced..."
|
|
button for your interface. You will see a "DNS" tab where you
|
|
can click "+" and enter 127.0.0.1 in the "DNS Servers" section.
|
|
|
|
By default, dnscrypt-proxy runs on localhost (127.0.0.1), port 53,
|
|
balancing traffic across a set of resolvers. If you would like to
|
|
change these settings, you will have to edit the configuration file:
|
|
#{etc}/dnscrypt-proxy.toml
|
|
|
|
To check that dnscrypt-proxy is working correctly, open Terminal and enter the
|
|
following command. Replace en1 with whatever network interface you're using:
|
|
|
|
sudo tcpdump -i en1 -vvv 'port 443'
|
|
|
|
You should see a line in the result that looks like this:
|
|
|
|
resolver.dnscrypt.info
|
|
