Eventually, i intend to be adding the capability to chain multiple OpenVPN configurations together to enhance networking egress. This will provide an additional layer of obfuscation and security by routing traffic through multiple VPN providers sequentially.
Implementation Details
To achieve VPN chaining, we will use Docker containers to manage the OpenVPN connections. Each container will connect to a different VPN provider, and traffic will be routed through these containers in sequence.
Example Implementation
Prerequisites
Docker installed on the host machine
OpenVPN configuration files from both VPN providers (e.g., NordVPN and Mullvad VPN)
Step-by-Step Guide
Create Dockerfiles for Each VPN
Dockerfile for NordVPN Container
FROM alpine:latest
RUN apk add --no-cache openvpn
COPY nordvpn.ovpn /etc/openvpn/config.ovpn
CMD ["openvpn", "--config", "/etc/openvpn/config.ovpn"]
Dockerfile for Mullvad VPN Container
FROM alpine:latest
RUN apk add --no-cache openvpn
COPY mullvadvpn.ovpn /etc/openvpn/config.ovpn
CMD ["openvpn", "--config", "/etc/openvpn/config.ovpn"]
Build and Run the Containers
Build and Run NordVPN Container
docker build -t nordvpn-container -<<EOF
FROM alpine:latest
RUN apk add --no-cache openvpn
COPY nordvpn.ovpn /etc/openvpn/config.ovpn
CMD ["openvpn", "--config", "/etc/openvpn/config.ovpn"]
EOF
docker run --cap-add=NET_ADMIN --device /dev/net/tun --name nordvpn -d nordvpn-container
Build and Run Mullvad VPN Container
docker build -t mullvadvpn-container -<<EOF
FROM alpine:latest
RUN apk add --no-cache openvpn
COPY mullvadvpn.ovpn /etc/openvpn/config.ovpn
CMD ["openvpn", "--config", "/etc/openvpn/config.ovpn"]
EOF
docker run --cap-add=NET_ADMIN --device /dev/net/tun --net=container:nordvpn --name mullvadvpn -d mullvadvpn-container
Verification
To verify the VPN chaining setup, perform the following steps:
Check NordVPN Container Logs
docker logs nordvpn
Ensure that the NordVPN connection is established successfully.
Check Mullvad VPN Container Logs
docker logs mullvadvpn
Ensure that the Mullvad VPN connection is established successfully.
Verify Routing
Use a network utility like curl or wget from the Mullvad VPN container to confirm that traffic is routed through both VPNs:
docker exec -it mullvadvpn curl ifconfig.me
The IP address returned should correspond to Mullvad VPN, indicating that traffic is being routed through both VPN providers.
Conclusion
By implementing VPN chaining using Docker containers, we enhance the privacy and security of our network traffic. This setup routes traffic through two VPN providers, providing an additional layer of obfuscation to the traffic's origin.
