  • How many of you use SSH to manage your server?
    I'm using Slack Nebula as a simple VPN mechanism. Nebula is how I network all of my computers together. It works 90% of the time (until you have other VPNs on, like work VPNs, then it can get confused, but hey).
  • I am tired of people in this sub treating VPN as "the golden hammer"
    You should add Nebula to the list, essentially zerotier but open source.
  • Smb over wireguard/tailscale/openvpn slow try nebula | 2021-10-02
    I currently have reasons for using smb over long distances which introduces latency and was struggling to get speeds faster than dialup. Every forum and reddit posts suggest MTU and optimizing things.. I couldn't get it work no matter what I did. So I setup my own Nebula lighthouse node mesh network (a lot like tailscaile but self hosted) and tried smb over that network instead. I was instantly able to saturate my bandwidth. Hope this helps
  • Wg-access-server: An all-in-one WireGuard VPN solution with a web UI | 2021-10-01
    Have you looked into It uses X509 cert for auth.

    Although for my home lab, using X509 is more of a minus than a plus due to complexity involved.

  • Headscale: Open-source implementation of the Tailscale control server | 2021-09-17
    Another similar project to Tailscale, for those in the market:

    Crazy simple, fully open source, trivial to self-host. Maybe not as featureful as Tailscale, but imo that can be a feature unto itself.

  • Tailscale free for open source projects | 2021-09-17
    As other have suggested, Nebula ( is pretty elegant. It has groups-based access built in which is extremely convenient.

    You can bolt-on SSO fairly easily - just create a certificate signing service. I created in a weekend, so its fairly easy to add a SSO flow in.

  • Ask HN: What problem are you close to solving and how can we help? | 2021-08-29
    Apart from some smaller projects building on top of WireGuard, there's Tailscale [1]. One of the founders is Brad Fitzpatrick who worked on the Go team at Google before and built memcached and perkeep in the past.

    Outside of the WireGuard ecosystem there's ZeroTier [2] which has been around for a while and they're working on a new version; and Nebula [3] from Slack, which is likely to be maintained as long as Slack uses it.

    There might be others, but with tinc these four are the ones I've seen referred to most often.

  • How to manage a server despite an ISP’s restrictions
    That's pretty much the best solution. Nebula might reduce the latency a bit being mesh, but security and complexity wise they're similar to your proposed scheme.
  • Gitlab stuck behind CGNAT
    Similar is Slack's Nebula, although it's designed more for larger deployments I think, and Wireguard (part of the Linux kernel) which can be a bit tricky to setup manually. I think some of the solutions you listed actually use Wireguard internally.
