- Optimizing the network path between the server and clients.
- Reducing the number of hops in the network path.
Deployment and Configuration
Deploying and configuring WireGuard WebSockets involves setting up a server and client to establish a secure and encrypted connection. Here’s a step-by-step guide to help you get started:
Before configuring, ensure you have a basic understanding of WireGuard and WebSockets. You’ll also need a server running Linux or a similar Unix-like operating system.
Server Configuration
On the server, install WireGuard and its WebSocket module:
sudo apt-get update sudo apt-get install wireguard wireguard-tools wireguard-websocket
Generate a new WireGuard private key:
wg genkey | tee privatekey | wg pubkey | tee publickey
Create a new WireGuard interface:
sudo wg set wg0 private-key privatekey
Configure the WireGuard interface with an IP address and subnet:
sudo wg set wg0 address 10.0.0.1/24
Enable IP forwarding:
sudo sysctl -w net.ipv4.ip_forward=1
Configure WireGuard WebSockets:
sudo wg-quick ws0 wg0
Set up firewall rules to allow traffic on the WebSocket port:
sudo ufw allow 80
Client Configuration
On the client, install WireGuard:
