UPDATE (13:40 ET / 2024-07-05): Got the connection working via SMB. Literally the only thing I changed was moving to a credentials file rather than specifying credentials inline, so … I’ll be trying to figure out what mystery affliction prevented the connection before. Leaving this up because there are a bunch of great suggestions for troubleshooting this issue in the comments. Thanks everyone.

ORIGINAL POST:

Currently pulling out my hair. I have a Synology NAS with the tailscale service (everything up to date). I have a NixOS client laptop, everything up to date.

I’m simply (?) trying to connect to a share via tailscale, and I have not managed to find anything that works. I’ve been using NFS, but I’m fine with SMB … or carrier pigeons at this point.

Does anyone know of a step by step, detailed, current tutorial to accomplish accessing a Synology share via tailscale on a linux device? I would not have thought this would be challenging!

    It’s the same error regardless of whether I connect by tailscale IP (100.x.x.x) or the tailscale hostname, and it strongly suggests an issue on the Synology, but everything looks correct on the NAS (but I am by NO MEANS an expert):

    mount.nfs: access denied by server while mounting $IP:/volume1/$mount

      Then you need to ssh into both devices and confirm they can both ping each other via the tailscale interface as a starter. That will at least shownif you have a routing problem.

        Apologies for the delay. July 4th festivities and rescuing a kitten from a storm drain intervened (upside: we now have a kitten).

        I can ping the NAS from the client on the Tailscale IP (100.x.x.x) and the tailscale hostname. If I SSH to the NAS, I cannot ping the client machine, but everything on the NAS is available from the client other than the NFS share (and I think I remember reading that the Synology tailscale client does not support ping).

        I realize we’re sort of narrowing in on an NFS setting or possibly a firewall setting, and I appreciate your patience in going on this journey with me, but I have configured both according to, most relevantly, the tailscale documentation for connecting to a Synology NAS.

      I don’t use synology but it kind of seems like the synology has an allowlist for subnets that can connect to it. Do you know what service is hosting the file share?

        The allowlist for NFS allows the tailscale subnet and the local LAN subnet.

          Does tailscale have a consistent subnet? Can you connect to the NFS share over the LAN net?
