IKEv2 VPN Server on Docker

Recipe to build gaomd/ikev2-vpn-server Docker image.

Usage

1. Start the IKEv2 VPN Server

docker run -d --name ikev2-vpn-server --restart=always --privileged -p 500:500/udp -p 4500:4500/udp gaomd/ikev2-vpn-server:0.3.0

2. Generate the .mobileconfig (for iOS / OS X)

docker run -i -t --rm --volumes-from ikev2-vpn-server -e "HOST=vpn1.example.com" gaomd/ikev2-vpn-server:0.3.0 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 / OS X)

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

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

Usage for Windows

Replace Your_Server_IP_Address, Your_User_Name and Your_Password.
