The most convenient way is to use an USB-device as described in Voxel documentation.
This is a Lazy Dog for those who want to do it without USB.

The short example:
Code:
mkdir -p /etc/openvpn/config/client/
cd /etc/openvpn/config/client/
echo "username" >nordvpn.auth
echo "password" >>nordvpn.auth
server="$(curl --silent 'https://nordvpn.com/wp-admin/admin-ajax.php?action=servers_recommendations' | jq --raw-output 'limit(1;.[])|.hostname')"
wget -O /etc/openvpn/config/client/nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/$server.udp1194.ovpn
sed -i 's/auth-user-pass/auth-user-pass nordvpn.auth/g' nordvpn.ovpn
/etc/init.d/openvpn-client start

The long explanatory way:
Pre-requisites:


Do It:
  1. Logon (From your web-browser):
    http://www.routerlogin.net

  2. Enable Telnet:
    http://www.routerlogin.net/debug.htm
    Check (Set a tick in the box for) "Enable Telnet". (No apply needed)

  3. Login to the router using telnet:
    Hold down the Windows Key, then press the “R“ key.
    The Run dialog box appears. In the Open: window, type:
    cmd
    Click OK.
    Code:
    telnet www.routerlogin.net
    The password is the same as from the normal router login page http://routerlogin.net

  4. Create the directory to put your OpenVPN-client configuration:
    Code:
    mkdir -p /etc/openvpn/config/client/

  5. Change to the directory:
    Code:
    cd /etc/openvpn/config/client/

  6. Create your NordVPN login credentials (user id and password) file:
    Code:
    echo "username" >nordvpn.auth
    echo "password" >>nordvpn.auth

  7. Download your preferred server configuration file from NordVPN:
    Download the server configuration file from NordVPN
    In a web-browser go to: https://nordvpn.com/ovpn/

    Find the line with the server you want to connect to.

    Right-click "Download UDP" to the right of the server name and chose: "Copy link address"

    In your router telnet windows, write (ending with a blank/space character, and without pressing enter!)
    Code:
    wget -O nordvpn.ovpn
    #Right-click at the end of what you just wrote to paste the server name, ending up with a line like:
    Code:
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/uk1000.nordvpn.com.udp1194.ovpn
    #Press the return key to download the server configuration file.

    Download the server configuration file from NordVPN
    In a web-browser go to: https://nordvpn.com/servers/tools/
    • Adjust server preferences: Select preferred country
    • Show advanced options:
      "Standard VPN"
      Select Security Protocol: "OpenVPN UDP"
    • Server recommended for you: Show available protocols:
      Right-click "Download config" and chose: "Copy link address"

    In your router telnet windows, write (ending with a blank/space character, and without pressing enter!) :
    Code:
    wget -O nordvpn.ovpn
    #Right-click at the end of what you just wrote to paste the server name, ending up with a line like:
    Code:
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_udp/servers/se234.nordvpn.com.udp.ovpn
    #Press the return key to download the server configuration file.

    Code:
    #Use one of these examples depending on where you want to connect:
    
    #To get the server recommended by NordVPN (nearest you with lowest load):
    server="$(curl --silent 'https://nordvpn.com/wp-admin/admin-ajax.php?action=servers_recommendations' | jq --raw-output 'limit(1;.[])|.hostname')"
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/$server.udp1194.ovpn
    
    #UK:
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/uk1000.nordvpn.com.udp1194.ovpn
    
    #US:
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/us1859.nordvpn.com.udp1194.ovpn
    
    #Sweden:
    wget -O nordvpn.ovpn https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/se108.nordvpn.com.udp1194.ovpn

  8. Change the server file to recognize your login information:
    Code:
    sed -i 's/auth-user-pass/auth-user-pass nordvpn.auth/g' nordvpn.ovpn

  9. Start the OpenVPN-client
    Code:
    /etc/init.d/openvpn-client start

  10. That's all! The OpenVPN-client will be started automatically at every reboot.
    You have to repeat these steps after updating the router firmware.

  11. To see the log-file:
    Code:
    cat /var/log/openvpn-client.log

  12. To see status and more info about the OpenVPN-client, install my add-on:

Thank you for the details kamoj. Unfortunately I can't get VPN working. I've tried with both Mullvad and NordVPN and no luck. Log message is always the same. Any ideas?

No, not really.
But you buffers gets too big!
Voxel client sets them to 786432, but you have 1048576.
So maybe your .ovpn file overrides Voxels settings.
What is your router?
You seem to try to connect to "datapacket.com". I don't even know they have an OpenVPN server.
Maybe you are trying to run your own server on a rented computer?
That is not either NordVPN or Mullvad, so I suggest you start a new thread about your issue!

I have the R7800 router running Voxel v64 firmware.

This is really bizarre, because now it's working and I didn't change anything. I tried the file you have in your instructions
https://downloads.nordcdn.com/configs/files/ovpn_legacy/servers/uk1000.nordvpn.com.udp1194.ovpn and other ovpn files from both providers to no avail. Now they're all working.

I followed your above directions word for word.

With these relatively timidly powered devices such as our routers are, sometimes just being patient long enough is enough to let them finally configure themselves as we direct them. ;)

Yes, very strange...
Which service do you find the fastest?

I just signed up at NordVPN for a 7-day trial to test the code, and it worked perfectly.
But I had very varying speed depending on connected server. Even when using the by NordVPN recommended server I only got 10 Mbps down+up sometimes.

I tried different servers and the speed difference between servers is terribly big.
It's impossible to know which server to connect to.

The best I found:
At this server I got a maximum speed of: 106/9 Mbps:
https://downloads.nordcdn.com/configs/files/ovpn_udp/servers/se114.nordvpn.com.udp.ovpn

At this server I got a maximum speed of: 124/9 Mbps:
https://downloads.nordcdn.com/configs/files/ovpn_udp/servers/se144.nordvpn.com.udp.ovpn

I have contacted NordVPN support that were very fast and helpful.
But they confirm that there is no way for the router to know which server to connect to,
so speed can be very slow if you are not lucky.

They asked me to use the "recommended server" as I described above, but that does not give better speed for me.
It seems completely random to me.

The support will make a suggestion to enable some generic .ovpn file/server that can do a correct speed balancing/estimate.

For me NordVPN is not usable due to the enormous difference between their routers, and no way to find a fast one.
I'll cancel my trial and hope for good news from NordVPN in the future.

NordVPN has been good for me in the US. Which provider do you use?

I've been messing around with VPN and something got hosed I can't get out to the internet at all. I can't even ping sites from the command line on the router whether connected to VPN or not.

Any ideas?

You have a surfshark.ovpn file that is incorrect?!
How did you get that one?
Please check it with:
Code:
cat /etc/openvpn/config/client/surfshark.ovpn

No problem!
I don't know what you have done.
Your file is not a zip-file.
Your file is not a .ovpn-file either.

To get the .ovpn file for surfshark, do like this (instead of point 7 in my first posting):
Code:
mkdir -p /tmp/surfshark
cd /tmp/surfshark
wget https://account.surfshark.com/api/v1/server/configurations
unzip configurations
\rm configurations *tcp*
\ls
#Now copy one of these .ovpn files, e.g.
\cp sg-sng.prod.surfshark.com_udp.ovpn /etc/openvpn/config/client/surfshark.ovpn
cd /etc/openvpn/config/client/

that makes my ping high.
Try stubby just the same
can i disable dnscrypt2 and stubby?

Code:
/etc/init.d/dnscrypt-proxy-2 stop
nvram unset dnscrypt2
/etc/init.d/stubby stop
nvram unset stubby
nvram commit
PS
This thread is about NordVPN.
I think you shall start a new thread with your Speedtest and ping problems.

Hi Kamoj, I have the same problem with NordVPN servers, the speed is totally random, sometimes it connects to a speedy server and other times to a 10|10 server. What vpn service can you recommend?

Maybe NordVPN has grown too fast. Maybe they will catchup in due time. Who knows?

There is no service recommendable for everyone.
You need it for privacy or to change country etc

Try to find providers where you live and do a trial subscription!

(I found one near my home that even publish UL/DL speeds for the servers,
so it was easy to make a script to get the fastest connection at all times.)

Wishing you good luck in your search!
