Windows 10 - use VPN for DNS only

Post by ianmc » Wed Jan 19, 2022 9:23 am

Hi all

I am quite new to openvpn.

I hired a basic linode server, for a vpn, tracking/ad blocking - using pi hole + a the unbound dns resolver.

The script I used to setup openvpn was from here: https://github.com/angristan/openvpn-install
It went well.

I setup client for my phone, laptops and PC.

My PC is dual boot window/linux.
Linux is for main use.
Windows is for gaming only.
I wish to use the vpn connection in windows for DNS requests ONLY, to minimize latency in games.

The apt-cache policy openssh-server in the server spurted out:

Installed: 1:8.2p1-4ubuntu0.4
Candidate: 1:8.2p1-4ubuntu0.4

My home LAN is 192.168.1.0.24
The TUN device is 10.8.0.0/24
Home router address/DNS 192.168.1.1
The vpn router address/DNS 10.8.0.1 (pihole)

So it seems I need to put something in a modified client file concerning routes. I am not quite sure.
help appreciated.

Thanks.

Then you do not require push "redirect-gateway" in your server config.

Thanks for the reply.

I only wish to do this for one specific client, specifically when using windows 10 on my home PC.
If I did that I think it would do it for all.
For the rest I want all traffic through the vpn as expected.

How is this configured?

Thanks

If you wish to do such thing, you should configure your openvpn sessions manually.
you can create a new /etc/openvpn/serverX.conf with new private key and different port number.
Then omit `push "redirect-gateway"` from your new config.

It seems I found another way.


I have a client setup, specifically my home PC.
It is dual boot windows/linux.
In linux I use the ovpn file generated, and all traffic is through the vpn as expected.
In windows, I copied the .ovpn file and added:

pull-filter ignore "redirect-gateway"

In windows I use the second ovpn file, and it seems to have worked.

Apparently it does not always work.
Thanks for the replies

The right way would be to setup your server correctly. To do that you will need to read the howto.
