Connecting to WireGuard VPN from Linux

Starting from KeeneticOS 3.3, it is possible to use a WireGuard VPN tunnel to remotely connect to the local network of the Keenetic router.

Importante

If you plan to set up your Keenetic as a VPN server, make sure that it has a public IP address, and if you use KeenDNS, that it works in 'Direct access' mode, which also requires a public IP address. If any of these conditions are not met, you will not connect to such a server from the Internet.

First, you need to configure the WireGuard server on the Keenetic device. The following instruction shows the process: Configuring a WireGuard VPN between two Keenetic routers. Then move on to the VPN client setup.

Here is an example of how to connect to the VPN server from a Linux operating system, using CLI (terminal) for setting up the connection in Ubuntu 18.04 LTS and the graphical interface in the Linux Mint 19.3 LTS distribution.

To establish a connection to a Keenetic WireGuard server on a Linux-based computer, you must install the WireGuard package using the built-in apt package manager.

Installation and configuration options in the terminal
  1. Launch the terminal and install the necessary packages needed for WireGuard to work in the terminal and configure the connection in NetworkManager GUI (a program for managing network connections): application package, kernel module, kernel header files.

  2. Create a Private Key and a Public Key:

    [my@my-wrk-lnv ~]$ cd /etc/wireguard/
    [my@my-wrk-lnv wireguard]$ umask 077
    [my@my-wrk-lnv wireguard]$ sudo -i
    [sudo] password for my:
    root@my-wrk-lnv:~# cd /etc/wireguard/
    root@my-wrk-lnv:/etc/wireguard# wg genkey > private-key
    root@my-wrk-lnv:/etc/wireguard# wg pubkey > public-key < private-key
    root@my-wrk-lnv:~# exit
    [my@my-wrk-lnv wireguard]$ sudo cat private-key AOSXWm+sXxRuu/Uo8lysE4PIwVZTRDD+YV6w3HicGHg=
    [my@my-wrk-lnv wireguard]$ sudo cat public-key xxKBcZlhZlbjW7yFuhZ08l294HBAp2I/iM05YE8vs0Y=
    [my@my-wrk-lnv wireguard]$ cd -
    [my@my-wrk-lnv ~]$

    Importante

    If you get the 'Permission denied' result after typing cd /etc/wireguard/, you do not have root access to read the directory.

    [my@my-wrk-lnv ~]$ cd /etc/wireguard/
    bash: cd: /etc/wireguard/: Permission denied

    Change the owner, who can access the directory without root access rights:

    [my@my-wrk-lnv ~]$ sudo chown -R my /etc/wireguard/
    [my@my-wrk-lnv ~]$ cd /etc/wireguard
    [my@my-wrk-lnv wireguard]$

    After configuring the connection, you can change back the owner for access to the default directory:

    [my@my-wrk-lnv wireguard]$ cd - /home/my
    [my@my-wrk-lnv ~]$ sudo chown -R root /etc/wireguard/
  3. Create the wg-client.conf configuration file:

    [my@my-wrk-lnv wireguard]$ sudo touch wg-client.conf
    [my@my-wrk-lnv wireguard]$ ls -1
    private-key
    public-key
    wg-client.conf
  4. Let's add the connection settings to the created configuration file wg-client.conf by opening the file with a text editor, for example, nano:

    [my@my-wrk-lnv wireguard]$ sudo nano wg-client.conf
    [sudo] password for my:
    
    [Interface]
    PrivateKey = AOSXWm+sXxRuu/Uo8lysE4PIwVZTRDD+YV6w3HicGHg=
    Address = 172.16.82.5/24
    DNS =
    
    [Peer]
    PublicKey = 1YVx+x3C817V9YdhUtpUhzyDLVj5tnK2m//WjFGynm4=
    AllowedIPs = 172.16.82.1/32, 192.168.22.0/24
    Endpoint = wgwrkserver.dynns.com:16631
    PersistentKeepalive = 5
    [my@my-wrk-lnv wireguard]$ sudo nano wg-client.conf
    [sudo] пароль для my:
    
    [Interface]
    PrivateKey = AOSXWm+sXxRuu/Uo8lysE4PIwVZTRDD+YV6w3HicGHg=
    Address = 172.16.82.5/24
    DNS =
    
    [Peer]
    PublicKey = 1YVx+x3C817V9YdhUtpUhzyDLVj5tnK2m//WjFGynm4=
    AllowedIPs = 172.16.82.1/32, 192.168.22.0/24
    Endpoint = wgwrkserver.dynns.com:16631
    PersistentKeepalive = 5

    Configuring client's [Interface]:

    In the client interface's 'PrivateKey' field, enter the private key created in step 2.

    The key can be viewed with the cat command:

    [my@my-wrk-lnv wireguard]$ sudo cat private-key
    AOSXWm+sXxRuu/Uo8lysE4PIwVZTRDD+YV6w3HicGHg=

    In the 'Addresses' field of the client interface, specify the IP address in IP/bitmask format — 172.16.82.5/24 (this is the internal address of the tunnel). Another subnet can be used, but it must be chosen from a private address range and avoid overlap with other subnets configured on these devices.

    Importante

    If you have Internet access through a WireGuard VPN tunnel configured on the [Interface] side of the client, you must specify the DNS server in the 'DNS=' field.

    In our example, the address of the DNS server from Google 8.8.8.8:

    [Interface]
    PrivateKey =AOSXWm+sXxRuu/Uo8lysE4PIwVZTRDD+YV6w3HicGHg=
    Address = 172.16.82.5/24
    DNS = 8.8.8.8
    
    [Peer]
    PublicKey = 1YVx+x3C817V9YdhUtpUhzyDLVj5tnK2m//WjFGynm4=
    AllowedIPs = 172.16.82.1/32, 192.168.22.0/24
    Endpoint = enpwgwrkserver.dynns.com:16631
    PersistentKeepalive = 5

    Configuring the server's [Peer]:

    In the 'Public key' field, insert the public key of the server, which can be copied to the clipboard from the WireGuard settings in the router's web interface:

    wireguard-linux-01-en.png

    In the 'AllowedIPs' field, enter allowed IP addresses in IP/bitmask format — 172.16.82.1/32 (the internal server address) and 192.168.22.0/24 (address of the local segment of the Keenetic router).

    In the 'Endpoint' field, enter the public IP address or domain name of the WireGuard server and the listening port on which the WireGuard client will establish communication.

    In the 'PersistentKeepalive' field, enter the frequency of attempts to check the availability of the remote side of the connection. Usually, a 3-5 second interval between checks is enough.

  5. Set up a remote connection on the side of the previously configured WireGuard server.

    Connect to the router's web interface and go to the 'Other connections' page in the 'Internet' menu. Click on the previously created WireGuard connection ('wg-keenetic-server') and add the peer's settings. Click on 'Add peer' to open the peer settings window, in which you specify the name of the tunnel 'wg-ubuntu-home'.

    In the 'Public key' field, insert the key created in step 2.

    As a reminder, the key can be viewed with the cat command:

    [my@my-wrk-lnv wireguard]$ sudo cat public-key
    xxKBcZlhZlbjW7yFuhZ08l294HBAp2I/iM05YE8vs0Y=

    In the 'Allowed IPs' field, specify the address from which traffic will be allowed to the server in IP/bitmask format — 172.16.82.5/32

    In the 'Persistent keepalive' field, you must specify the frequency of attempts to check the availability of the remote side of the connection. Usually, a 10-15 second interval between checks is enough. The default value of the 'Persistent keepalive' in the Keenetic peer settings is 30 seconds.

    Click 'Save'.

  6. Create an automatic WireGuard connection at OS startup via the Systemd initialization system, which allows you to start and manage Linux system daemons:

    [my@my-wrk-lnv ~]$ sudo systemctl enable wg-quick@wg-client.service
    Created symlink /etc/systemd/system/multi-user.target.wants/wg-quick@wg-client.service → /lib/systemd/system/wg-quick@.service.

    Importante

    In the service name ***.service enter the configuration name wg-client.conf

  7. Start the WireGuard connection:

    [my@my-wrk-lnv ~]$ sudo systemctl start wg-quick@wg-client.service

    Importante

    If the service does not start, you should check the boot log with the command systemctl status wg-quick@wg-client.service or journalctl -xe:

    [my@my-wrk-lnv ~]$ systemctl status wg-quick@wg-client.service

  3. Reboot the computer and check the availability of Wireguard settings in the Network Connections panel:

Configuring the connection to the Wireguard server:
  1. Generate Private and Public keys, as described in 'Installation and configuration options in the terminal' (2nd step).

    If the keys were previously generated in the system, you would need to view them in the terminal and copy them to the clipboard one by one:

    [my@my-wrk-lnv wireguard]$ sudo cat private-key
    0CwJzxW0yOG4I9XWl9Wo9nzpxen2G0VlTAxD7XEBVmE=
    [my@my-wrk-lnv wireguard]$ sudo cat public-key
    M2LeCzN8mFLpa6Xz3BNHFgtNt8kY4wluiwt+NJFTgxk=
  2. Copy the Private key and paste it into the Private Key field of the tunnel settings:

    wireguard-linux-04-en.png
  3. Copy the public key and paste it into the previously configured WireGuard server in the Public Key field.

    In the 'Allowed IPs' field, specify the address from which traffic will be allowed to the server in IP/bitmask format — 172.16.82.8/32

  4. In the 'Public Key' field, enter the public key of the server, which can be copied to your computer's clipboard from the WireGuard settings in the router's web interface:

    wireguard-linux-06-en.png
    wireguard-linux-07-en.png

    In the 'Allowed IPs' field, specify allowed IP addresses in IP/bitmask format — 172.16.82.1/32 (the internal server address) and 192.168.22.0/24 (address of the local segment of the Keenetic router).

    In the 'Endpoint' field, specify the public IP address or domain name of the WireGuard server and the listening port on which the WireGuard client will establish the connection.

    In the 'PersistentKeepalive' field, specify the frequency of attempts to check the availability of the remote side of the connection. Usually, a 3-5 second interval between checks is enough.

  5. In the IPv4 tab in the Routes section, add a route to the local network segment of the Keenetic router:

    wireguard-linux-08-en.png
  6. Connect to the Wireguard server and ensure there are no error messages.

    To check the server availability, you can send ICMP packets to the IP address of the local segment of your Keenetic router:

    [my@my-wrk-lnv ~]$ ping -c 10 -s 100 192.168.22.1
