WireGuard VPN is a newer VPN protocol that is designed to be faster, more secure, and simpler than older VPN protocols such as OpenVPN. WireGuard uses modern cryptographic techniques to provide better security and performance compared to other VPN protocols. Here are some of the main advantages of using WireGuard VPN over OpenVPN:
- Faster Speeds: WireGuard is designed to be faster than OpenVPN due to its streamlined code and more efficient encryption algorithms. This means that WireGuard VPN can offer faster connection speeds, lower latency, and a more responsive browsing experience.
- Better Security: WireGuard VPN uses modern cryptographic techniques such as ChaCha20 for encryption and Poly1305 for message authentication, which are considered to be more secure than the encryption algorithms used by OpenVPN. WireGuard also uses a simpler and more secure key exchange process, which makes it less vulnerable to attacks.
- Simpler Configuration: WireGuard VPN has a simpler and more intuitive configuration process compared to OpenVPN. This means that it is easier to set up and maintain WireGuard VPN servers and clients.
- Improved Battery Life: WireGuard VPN is designed to be more battery-efficient than OpenVPN, which is important for mobile devices such as smartphones and tablets. This is because WireGuard uses fewer resources and does not require as much processing power as OpenVPN.
In summary, WireGuard VPN offers faster speeds, better security, simpler configuration, and improved battery life compared to OpenVPN. These advantages make WireGuard a great choice for users who want a faster and more secure VPN experience. However, it should be noted that WireGuard is still a relatively new protocol and may not be as widely supported as OpenVPN by VPN providers and clients.
Create a new directory for your project and create a file named
docker-compose.yml inside it. add the following to it.
--- version: "2" services: wireguard: image: lscr.io/linuxserver/wireguard:latest container_name: wireguard cap_add: - NET_ADMIN - SYS_MODULE environment: - PUID=1000 - PGID=1000 - TZ=Etc/UTC # e.g. America/New_York - SERVERURL=wireguard.domain.com #External IP or domain name for docker host. can be auto, the container will determine the IP - SERVERPORT=51820 # server port - PEERS=desktop,tablet,phone,phone2,fridge,toaster,cat_collar #names of all devices you want to add to this vpn - PEERDNS=126.96.36.199 #dns server IP to use with wireguard (cloduflare shown) - INTERNAL_SUBNET=10.13.13.0 #your internal subnet for the VPN - ALLOWEDIPS=0.0.0.0/0 # what IPs can connect to your server? leave at 0.0.0.0 unless you have a specific reason. - PERSISTENTKEEPALIVE_PEERS= #optional - LOG_CONFS=true # Generated QR codes will be displayed in the docker log. volumes: - ./config:/config # - /lib/modules:/lib/modules # only enable if using custom wireguard modules. ports: - 51820:51820/udp sysctls: - net.ipv4.conf.all.src_valid_mark=1 restart: unless-stopped
the ENV variables are explained in the comments but the rest of the commands are explained below :
image: Specifies the Docker image to use for the container, in this case
container_name: Sets the name of the container to “wireguard”.
cap_add: Grants the container the
NET_ADMINcapability so it can run its own network.
environment: Sets environment variables that configure the WireGuard server. Replace the placeholders with your desired values.
volumes: Mounts the host directories
/lib/modulesas volumes inside the container.
ports: Exposes port 51820/udp on the host so that WireGuard clients can connect to the server.
docker compose up -d : download images as needed and turn on the container.
docker compose down : bring down the container and disable the network. leaves the volumes on disk.
