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...
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.
Thanks! How do you handle that with internal DNS? I suppose you’d need to setup the exact same proxies on the internal and external server, and local DNS handles which one my domain it’s being resolved to?
Thank you for the detailed explanation. I am running Tailscale as a temporary solution to access some services, but I dislike that you have to set firewall rules basically twice (once in your local network and once in Tailscale). I suppose it would be similar for CF?
Thanks for the write up! I’ll definately check out your blog as well. A cloud gateway is something I’ve considered as well (especially when the costs are around $5 monthly). How do you handle authentication?
Make sure you have backups of your vault. Reliable backups.
Especially if you are just starting off with docker, you don't want to loose access to all your accounts because you f up some configuration (e.g. redeploy an updated image)
Appreciate it!
