Generate the WireGuard VPN Client Private and Public keys

In our previous guide to setup the WireGuard VPN server, we have already generated the keys for our test clients.

Hence, we will just copy the respective keys to the respective clients.

[[ -d /etc/wireguard/ ]] || mkdir /etc/wireguard/

In our setup, we have already copied the client keys to the respective clients;

On Ubuntu client

sudo ls -1 /etc/wireguard/
ubuntu.keyubuntu.pub.keywireguard.pub.key

Create WireGuard VPN Client Configuration

On each client system, create the configuration file. You would simply run the command below to create the configuration file.

Replace the client IP addresses and Private keys accordingly.

Ubuntu Client

sudo tee /etc/wireguard/wg0.conf << 'EOL'[Interface]PrivateKey = GODF2MimY+nATXMbjJUdCo19Q7edYEOg3PuegNSad1o=Address = 10.8.0.20DNS = 8.8.8.8[Peer]PublicKey = T6gaFyJEWRucHFzpJJFYPpFv6EH3r2lnXxLHMP8eshU=AllowedIPs = 10.8.0.0/24Endpoint = 192.168.56.104:51820PersistentKeepalive = 20EOL

Configure WireGuard VPN Server to Allow VPN Clients Connections

On your WireGuard VPN Server, you need to enable VPN clients peer to peer connections.

To enable this, you need to obtain the Public keys for each client. For example, in my setup, I have three clients whose public keys are generated already.

This has been done already in our WireGuard VPN Server setup. Check the link below;

Configure WireGuard VPN Server to Allow VPN Clients Connections

Running WireGuard VPN Client Service

On the WireGuard VPN Clients, you can start the service now either using the wg-quick or systemd!;

sudo systemctl start wg-quick@wg0

Checking the status;

systemctl status wg-quick@wg0

Once done on all clients, check IP address assignment.

ip add show wg0

Verify Interconnection Between VPN Server and Clients

Confirm client connection to the server;

sudo wg
interface: wg0 public key: ucQSU4bqZn0Pll+hgfLNZC8JNDMymOGifyiwp/iKIjc= private key: (hidden) listening port: 46230peer: T6gaFyJEWRucHFzpJJFYPpFv6EH3r2lnXxLHMP8eshU= endpoint: 192.168.56.104:51820 allowed ips: 10.8.0.0/24 latest handshake: 40 seconds ago transfer: 476 B received, 628 B sent persistent keepalive: every 20 seconds

You can run the same command on the server as well.

Now, try to ping the vpn server on the client;

ping 10.8.0.1 -c 3
PING 10.8.0.1 (10.8.0.1) 56(84) bytes of data.64 bytes from 10.8.0.1: icmp_seq=1 ttl=64 time=2.60 ms64 bytes from 10.8.0.1: icmp_seq=2 ttl=64 time=1.80 ms64 bytes from 10.8.0.1: icmp_seq=3 ttl=64 time=1.69 ms--- 10.8.0.1 ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2006msrtt min/avg/max/mdev = 1.689/2.032/2.604/0.406 ms

Ping the client from the server;

ping -c 4 10.8.0.20
PING 10.8.0.20 (10.8.0.20) 56(84) bytes of data.64 bytes from 10.8.0.20: icmp_seq=1 ttl=64 time=1.30 ms64 bytes from 10.8.0.20: icmp_seq=2 ttl=64 time=2.03 ms64 bytes from 10.8.0.20: icmp_seq=3 ttl=64 time=1.43 ms64 bytes from 10.8.0.20: icmp_seq=4 ttl=64 time=1.82 ms--- 10.8.0.20 ping statistics ---4 packets transmitted, 4 received, 0% packet loss, time 3005msrtt min/avg/max/mdev = 1.302/1.646/2.033/0.293 ms

Your clients should now be able to communicate with each other.

And that concludes our guide on how to install WireGuard VPN client on Ubuntu 24.04.
