VPN (PPTP) for Docker

This is a docker image with simple VPN (PPTP) server with chap-secrets authentication.

PPTP uses /etc/ppp/chap-secrets file to authenticate VPN users.
You need to create this file on your own and link it to docker when starting a container.

Example of chap-secrets file:

# Secrets for authentication using PAP
# client    server      secret      acceptable local IP addresses
username    *           password    *

Starting VPN server

To start VPN server as a docker container run:

docker run -d --privileged -p 1723:1723 -v {local_path_to_chap_secrets}:/etc/ppp/chap-secrets mobtitude/vpn-pptp

Edit your local chap-secrets file, to add or modify VPN users whenever you need.
When adding new users to chap-secrets file, you don't need to restart Docker container.

Connecting to VPN service

You can use any VPN (PPTP) client to connect to the service.
To authenticate use credentials provided in chap-secrets file.

Troubleshooting

Docker 1.7.x and connection issues

After upgrading from Docker 1.3.0 to Docker 1.7.1 the containers started from image mobtitude/vpn-pptp stopped accepting connections to VPN without any reason.
Connections were dropped after timeout.

It looked like Docker deamon didn't forward packets for GRE protocol to container.

One of the possible solutions is to start container with networking mode set to host by adding param --net=host to run command:

docker run -d --privileged --net=host -v {local_path_to_chap_secrets}:/etc/ppp/chap-secrets mobtitude/vpn-pptp

Note: Before starting container in --net=host mode, please read how networking in host mode works in Docker:
