⁠IKEv2 VPN Server on Docker

Recipe to build karhm/ikev2-server⁠ Docker image.

⁠Usage

⁠1. Start the IKEv2 VPN Server

⁠Via command line:

docker run --cap-add=NET_ADMIN -d --name ikev2-server --restart=always -p 500:500/udp -p 4500:4500/udp -e "HOST=<SERVER_IP>OR<FQDN>" karhm/ikev2-server:latest

⁠Via docker compose

version: '3'

services:
  vpn:
    image: karhm/ikev2-server
    container_name: ikev2-server
    ports:
      - "500:500/udp"
      - "4500:4500/udp"
    environment:
      HOST: "<SERVER_IP>OR<FQDN>"
      HOSTNAME: "<SERVER_IP>OR<FQDN>"
    cap_add:
      - NET_ADMIN
    restart: always

⁠2. Generate the .mobileconfig (for iOS / macOS)

docker exec -it ikev2-server generate-mobileconfig > ikev2-vpn.mobileconfig

Be sure to replace vpn1.example.com with your own domain name and resolve it to you server's IP address. Simply put an IP address is supported as well (and enjoy an even faster handshake speed).

Transfer the generated ikev2-vpn.mobileconfig file to your local computer via SSH tunnel (scp) or any other secure methods.

⁠3. Install the .mobileconfig (for iOS / macOS)

• iOS 9 or later: AirDrop the .mobileconfig file to your iOS 9 device, finish the Install Profile screen;

• macOS 10.11 El Capitan or later: Double click the .mobileconfig file to start the profile installation wizard.

⁠Technical Details

Upon container creation, a shared secret was generated for authentication purpose, no certificate, username, or password was ever used, simple life!
