DNS tunneling only

DNS tunneling only

[Mario García]

Hi,


Is it possible to tunnel DNS requests only from the client to the 
wireguard server?

There are a lot of OpenVPN projects that use this feature to have a 
"clean internet" without ads in the devices (android, pc,...) like DNS66 
app.

I use a OpenVPN server in a free tier Google Cloud VPN but it is laggy 
and a battery killer so I would like to move to wireguard instead of IPSec.


Thanks in advance

Yes... easy, if you want the responses to those requests going through
the tunnel as well.

It is just a tunnel, what you put in there is up to you. So add a
route to your DNS server only via the tunnel, leave the default route
as it is.

And no, there is no magic button that will do exactly that.
