docker-openvpn-gateway

The script runs an openvpn client in a docker container and manages iptables rules such that the host machine acts as a VPN network gateway. The host machine routes network traffic from the primary network interface to the established VPN tunnel.

NOTE: No filtering based on the source IP is performed. Adjust the script if the host machine can receive and route packets from unauthorized devices (e.g. by whitelisting a source IP range using iptables).

Usage

• Modify the openvpn configuration file path if required.
• Run docker-vpn-gateway start to start the service.
• Run docker-vpn-gateway stop to stop the service.
• Adjust the default gateway of the devices whose network traffic needs to be tunneled via the gateway using DHCP or manual configuration.

The script is intended to be launched as a systemd service.
