Toot

I have a kinda technical question. I'm trying out #tailscale . I set it up on my home desktop and on a laptop. The desktop is also sharing the subnet 10.0.0.0/24, my local network.

If I set up my laptop to be outside my local network, it can ping machines on my local network through the tailnet. For example 10.0.0.203 which is my NAS. But it can't ping them by name (it can if it's on the local network).

ping 10.0.0.203 <-- works locally or through tailnet

ping qnap <-- works locally only

I would like file shares or other things to work the same on the laptop whether it's on the local network or through the tailnet.

Also if the NAS IP changes it would continue working by name but not by IP. Also I don't want to have to keep a hosts file up to date...

Is there a simple way to make this work? I don't want to have to maintain my own DNS server unless it's the only way...

I sent this question to tailscale support but haven't gotten a reply yet, I suspect it's too basic and you're expected to know this if you're using it at all...

I manage a very minimal network at home, and just want a simple solution without having to become a whole IT department...

@skylark13 is qnap resolvable by your network's DNS server, or is it via an announce-based protocol like bonjour or SMB/NETBIOS? announce/multicast based protocols usually don't work through VPNs unless you explicitly enable some kind of multicast forwarding through the VPN (I haven't tried this with tailscale though, sorry!)

@Foritus Interesting, you use some words I know but don't necessarily understand, thank you! I have things to read up on.

I suspect the name is not resolved through DNS because I only have my home router and have never configured anything specific to my NAS on it, the name qnap just worked when I plugged the NAS to my network. So I suspect you're on to something here. I'll try to find tailscale-specific information about this.

Thanks again!

@Foritus Thinking about it, what I'm worried about (the IP changing) could be solved by giving it a static IP in my router. Then I could use its IP or give it a name in the hosts file without any problems in the future...

Still, if there's a nice way to make this work, it would be cool, and it's a learning opportunity, so I'll do a bit of research in the direction you suggested.
