  • Unfortunately not at the moment, as all is kinda fiddled and setup manually, but I’m redoing my home lab in a couple of weeks. Send me a message and I’ll send you the docker image or script!

    But basically I did the following:

    • enable ipv4 forwarding
    • configure and start VPN tunnel
    • set the default route to the tunnel
    • set the gw for reaching the remote vpn server to the local gw
    • sets routes for the local network to the local gw

    If your vpn goes down, the default route shall still point to the remote gw, but as it isn’t there you also have a kill switch. Voila!

    I am looking into gluetun but haven’t tried it yet.

    Edit: this doesn’t protect you from someone snooping the traffic inside your local net, but protects it starting from the point where it leaves the local vpngw. The traffic is unencrypted between that and your client.







  • What I’m doing is using a dedicated VPN Gateway container. The instances running delicate services have a static default route to the GW-container.

    This is an extra step, but allows me add easily route other services or clients or even whole networks through my VPN without additional setup or specialized containers bundling both.

    Wanna use it on the phone? Change the gateway address. Wanna use it from my Linux machine? Add a static default route. Etc…

    Works flawlessly!


  • Of course! So in order to get maximum speed on your services, you wanna use a direct internal route when you’re inside your net. My understanding is, that when using an external cloud VPS with a proxy, local clients go through unnecessary routing…

    Local request --out--> external VPS (proxy) --request data from internal--> receive data on external proxy --send back--> local client

    So what I am saying, all requests are unnecessarily routed through the external VPS. So one would have to create an exact duplicate reverse proxy internally to avoid leaving the net. When accessing domain.com, the internal DNS returns the local proxy IP, when outside you receive the cloud VPS IP.

    Or am I missing something?

    Thank you for taking the time!
