I’ve read a lot of recommendations for tailscale and am on my way to try it out myself. Do you use Tailscale in the “normal” way or do you host your own Headscale server (as I’m planning to do)? Any pros and cons?

    Tailscale is super simple. Install it on two computers you want to be able to talk to eachother, doesn’t matter where they are as long as they have internet access. Authenticate with Tailscale on both computers and you are done.

    I’m a newbie in self-hosting and Tailscale is super powerful for me. Everything at home is accessible on my phone, mainly music server and radarr/sonarr for watching show on the go. No need for subdomain or reverse proxy.

    I use Tailscale as is. Mainly to connect to my devices but also for fancy stuff like this:

    Some of my servers are only available via Tailscale. They don’t have any open ports to the internet. Even authentication to these servers via SSH is handled by Tailscale SSH.

    I have some SMB shares on my local server and I gave access to it to some friends via Tailscale by sharing said server and lock it down ACLs. So people that have “shared” access can only access the server via SMB’s ports.

    One more thing I wanted to use but then stopped screwing around with it: Tailscale Funnel. I wanted to access some local webservices on my server via the internet without connecting to Tailscale first but also without opening ports on my local router. The downside of Funnel: no custom domains (yet). This means I would have to use their Tailnet name instead. Instead I went with Cloudflare Tunnel.

    One more thing that was annoying with Funnel: I wanted to use tsnet for quick file shares via a very basic HTTP server. Tsnet created “virtual” machines within mail Tailnet which I could then funnel to the internet. Unfortunately, Tailnet DNS propagation is absurdly slow. It’s not really made for on-demand funnel usage. It would work just fine while being connected to the Tailnet via Tailscale, but not via Funnel over the internet.

    All in all, I’m super happy with Tailscale. Setting things up was so absurdly easy and it just works.

      I’m curious, what’s the benefit of using Tailscale over setting up Wireguard yourself? Is it just not having to do all of the setup? Or do I misunderstand what the main use of Tailscale is?

        The main benefit of Tailscale are:

        • It solves the key distribution problem. If you have multiple Wireguard hosts in a mesh infrastructure, it can be tricky to change or remove a key quickly and consistently. No benefit if it’s only a single tunnel between 2 hosts.
        • It provides STUN/DERP services to connect hosts behind firewalls or NAT, without opening ports or redirections.

        Tailscale also provides more advanced services or configuration helpers, such a file sharing (in alpha), ACLs…

          Hmm, I guess my question would be how does this all work? I mean, is it not possible to configure STUN/DERP services yourself? Or add control lists yourself?

          I’m curious as to how all of this is done, not just to see if it’s possible (even if it’d be a headache) but for confirmation. Granted, networking is my worse subject when it comes to any related to computers. For ACLs, I guess Apparmor and/or SELinux profiles would be configured? The removing a key I can understand why it’s be a nightmare yourself, but how does Tailscale do it where it’s just so simple?

          EDIT: Another question I have is how does Tailscale work when I have a VPN for securing network traffic when browsing the internet etc.? Or is that just seamless?

            DISCLAIMER: I never used Tailscale. All I know about Tailscale I learned reading their “How it works” blogpost and documentation, because I wanted to understand the hype.

            Since nobody answered your questions, I’ll try my best. Just trust that I spent most of the last 25 years configuring security systems, including but not limited to VPNs.

            Hmm, I guess my question would be how does this all work?

            See my 2 links above.

            I mean, is it not possible to configure STUN/DERP services yourself?

            Of course it is, but it will be additional work, that most users are not willing/confident to do and Tailscale provides this service.

            Or add control lists yourself? […] For ACLs, I guess Apparmor and/or SELinux profiles would be configured?

            Deploying network ACLs on your hosts indeed does not require you to use Tailscale. However they provide an centralised way to manage and deploy them, without worrying about the underlying OS and ACL system. Or even requiring you to have access to the host, it could be an authorised user trying to access your Tailscale network.

            Note: AppArmor/SELinux are more “system/process ACLs”, not directly related to network ACLs. I’m oversimplifying a lot, they’re difficult to describe without knowing your sysadmin skills.

            The removing a key I can understand why it’s be a nightmare yourself, but how does Tailscale do it where it’s just so simple?

            Simple: they ask you to run an agent on all of your Tailscale hosts and connect to their centralised platform. To paraphrase their blogpost: config management is centralized, but that doesn’t matter because it carries virtually no traffic. It just exchanges a few tiny encryption keys and sets policies. The VPNs and their traffic are a distributed mesh.

            EDIT: Another question I have is how does Tailscale work when I have a VPN for securing network traffic when browsing the internet etc.? Or is that just seamless?

            I’m not sure to understand this question, so I’ll make an asumption: you’re asking what happens if you run Tailscale on a host that already has a VPN configured to access the Internet.

            Tailscale (and Wireguard under it) is already a VPN solution, and tunneling a VPN inside another VPN is generally discouraged. But as Tailscale is providing STUN/DERP, if they manage correctly the MTU issues and things like that, I don’t see an immediate reason why it should not work at all.

            You can configure Tailscale or Wireguard to create a VPN to access the Internet though.

            Once again, if you try to understand how Tailscale works, please read the links at the start of this post. RTFM, kids!

            On a more personal opinion, I find their solution clever and elegant. If I have the need for a distributed VPN solution in the near future, I will definitively consider it (or Headscale’s). For the moment, I’m fine with all my hosts connecting to my homelab, configuring a Wireguard tunnel for each roaming host, and opening ports and creating rules on my firewall. Compared to IPSec or OpenVPN tunnels, it seems almost too easy each time.

    If you want to really get into it, you can just hose a wireguard instance in a LXC then use iptables for all your routing.

    Relies only on FOSS software and gives you a pretty high level of control, but obviously is less intuitive

    I started using my own WireGuard config instead of using tail scale. Works great for me, though it does take more work up front.

      I started out with WireGuard. As you said its a little finicky to get the config to work but after that it was great.

      As long as it was just my devices this was fine and simple but as soon as you expand this service to family members or friends (including not-so-technical people) it gets too annoying to manually deal with the configs.

      And that’s where Tailscale / Headscale comes in to save the day because now your workload as the admin is reduced to pointing their apps to the right server and having them enter their username and password.

    @Jerry1098 Note my bias as I work for @tailscale, but:

    • I use the normal SaaS control plane with a tailnet shared with my husband

    • All our machines (towers, phones, laptops, steam decks, homelab nodes, virtual machines, etc) are on our tailnet and can access the storage on the NAS

    • I’ve written a number of custom tsnet services that do a wide range of things:

      • A private pastebin called tclip
      • A tool to check if my external Mullvad VPN on my NAS is working called vest-pit-near
      • Control endpoints for my CDN named XeDN
      • Other tools that let me do things like monitor Linux ISO release channels or experiments like an “infinite wiki” powered by ChatGPT and Llama 2

    • Almost all of my SSH connections are over Tailscale SSH, even over my local network, it’s likely that there’s more WireGuard and TLS traffic over the local network than there is clear text for anything else.

    • The NAS is mounted over Tailscale via SMB due to how MagicDNS intersects with Windows. It’s kinda neat and gives us a bunch of room for treating it as slower storage on our machines.

    • I share the preview version of my blog over Funnel. Previously I used node sharing to do that, but I started running into the 10 share limit. Sharing it over Funnel does mean that my development site does eventually make its way to random people, but really it’s okay.

    • When I travel I either use an exit node while on sketchy public WiFi. When I was at DEF CON recently I set up my own exit node on a budget host in Vegas so that I would have a moderately trustable egress point without suffering from high latency.

    I love it so much I ended up working there. It’s been one of my best tech finds in a long time. Feel free to ask me anything about how you can use Tailscale! I’m more than happy to answer.

    Honestly the main reason to use Tailscale for me is that it handles all the setup itself.
    I don’t really see the point in Headscale. If I wanted to worry about hosting and configuring I’d prolly just setup regular Wireguard.

    I’m using it for work.

    At first it was just me, I needed a remote access and I was not a big fan of using the chrome remote desktop that was the “solution” by their IT technician.

    So I’ve setup tailscale and used it to access the shared folders and Remote Desktop.

    After that, with my boss approval, I’ve set it up for several others person in the company and external consultant. Honestly it’s great, it just work, it’s secure and it is so easy to set up. With just few WhatsApp messages I can give instructions to have the remote desktop running, even to people not especially comfortable with computers.
