Hi everyone

Thanks for all the advice on buying a domain. Its a big week for me. Getting on grapheneos, buying a domain, and I also recently started self hosting my contacts and calendar. I love this way of life.

My original plan was to one of the xyz 1.1111b domains for $1 a year but most of the feedback I got said just go with cloudflare. Its a lot more money than I had planned but all the security features are baked in and I feel that’s worth the extra money.

Here are my questions. I use the latest version of truenas community

  1. How do I connect my domain to my server apps? I’ve got a series of apps I’d love to he able to access without tailscale and solely use the domain.
  2. I have heard the term DNS a million times but don’t really understand it. What do.I need to know about DNS to keep security up and stay protected
  3. I’d like to let family access my media server, are there any considerations I need to make?
  4. How can I use one domain to access multiple services on my server? Do I need to pay extra for subdomains?

Thank you for any advice

    At the moment, every time I want to access my server, I have to turn off my VPN so I can turn on tailscale.

    Yes, mobile devices typically cannot run two VPNs at once. There are two issues here, when at home and when out on other networks.

    At home, the solution is not to round-trip out to your VPN provider and then back into your network via the public Internet using your domain. Unfortunately. That creates a huge latency and bandwidth penalty when you are physically at home and unnecessary complexity.

    Instead, if you must use your VPN service while at home, you need to find the split tunnel settings to allow your phone to access the local network while connected to the VPN service. They usually hide that setting because it opens up the security of said services and allows some leaks, but it should be there.

    When out on other networks, it gets harder. If you get creative with networking, you could connect a computer to your commercial VPN service and have all your tailnet devices use it as an exit node, which has the nice benefit of paying the VPN service for “one device” and using as many as you want, but is dependent on your home network speed and a PITA to set up.

    Tailscale does integrate with one VPN provider so you can use one app for both tasks, but it may not be the provider you want. I don’t know If their direct competitors do the same, maybe shop around a bit. One VPN app for both use cases is what you want, not two different VPN apps.

    Finally, if none of the above works for you, then yes, you are back to accessing your self-hosted services via the public internet and your domain name while travelling and using your commercial VPN. You will have to secure the service, and that will take some learning to do safely. That will be a journey and not something you want to just throw together quickly. You might be able to restrict incoming connections to just your commercial VPN IP address range (in addition to all of the other proper config required) to further reduce the attack surface. Sorry, that is a bit of bad news.

    Edit: I have been seeing mTLS (client certificates) come up in selfhosting discussion more and more lately. If the particular service you are running has a walkthrough for that, including support for whatever client apps, it gets you almost to VPN level security. But most do not, and if they do, its alpha stage. However, keep an eye out for that in the self-hosting world as it may solve your issue in the future.
