WireGuard VPN Manager

A simple WireGuard VPN Manager to generate, assign, and manage profiles to users.

Requirements

• Cloudflare Access
• NodeJS 14 (LTS)
• One of the following:
  • A WireGuard Server Installation (tested in Ubuntu 20.04 LTS)
  • A Kubernetes Cluster

Kubernetes Cluster

Compatibility List:

• ✅ Google Kubernetes Engine (Node Pool must be using an Ubuntu OS)
• ✅ Azure Kubernetes Service
• ⚠️ Amazon Elastic Kubernetes Service (not tested)
• ❌ DigitalOcean Kubernetes Service (No UDP LoadBalancer support)

Installation Instructions:

1. Edit the k8s/manifest.yaml file. Fields that need to be edited will be commented with TODO: Edit me!!!.
2. Ensure that your kubectl context is set to the correct cluster.
3. If you don't have an nginx ingress installed, please install it using:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install ingress-nginx ingress-nginx/ingress-nginx

Use kubectl get service ingress-nginx-controller to obtain the External IP of the Nginx Ingress and ensure that your domain points to that IP address.

Note: The Nginx Ingress IP address and the VPN IP address will be different.

Enable Lets Encrypt SSL by running the following commands:

kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v0.14.1/cert-manager.crds.yaml
kubectl create namespace cert-manager
helm repo add jetstack https://charts.jetstack.io
helm install cert-manager --version v0.14.1 --namespace cert-manager jetstack/cert-manager

4. Run the command:

kubectl apply -f k8s/manifest.yaml

The Docker Image should automatically generate a wireguard configuration file and should get a external IP address for you.

The DNS Server is set to use the Kubernetes' built-in DNS server so users may connect to services within the Kubernetes Cluster through using the format: my-svc.my-namespace.svc.cluster.local

Running on Docker

docker run \
 --cap-add net_admin \
 --cap-add sys_module \
 -p 8080:8080 \
 -p 51820:51820/udp \
 -e CF_ACCESS_URI='https://yourdomain.cloudflareaccess.com' \
 -e DB_URI='mongodb://<your_mongodb_server>' \
 -e WIREGUARD_START_IP='10.69.0.0' \
 -e WIREGUARD_ENDPOINT='your.host:51820' \
 -e ALLOWED_IPS='0.0.0.0/0, ::/0' \
 -v <please specify a folder here to store the WireGuard config>:/etc/wireguard \

Notes for WireGuard Installation

When configuring your WireGuard Installation, ensure that the SaveConfig = true option is enabled in your WireGuard Interface. An example of what your configuration file should look like is as shown:

[Interface]
PrivateKey = <insert your private key here>
Address = 10.69.0.1/16
SaveConfig = true
ListenPort = 51820
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

In addition, this server is configured for 16 subnet bits with a subnet mask of 255.255.0.0. For a server IP address of 10.69.0.1/16, your usable IP ranges would be from 10.69.0.2/32 until 10.69.255.254/32 -- allowing up to around 60-thousand devices (theoretically).
