kecbigmt Tailscale Dev Server Access
Configure a local dev server for access from Tailscale-connected devices.
Prerequisites
- Devices on same Tailscale tailnet
- MagicDNS enabled (default for tailnets after 2022-10-20)
Steps
1. Get Tailscale Info
tailscale status
tailscale status --self --json | jq '.Self.DNSName, .TailscaleIPs[0]'
2. Bind Server to 0.0.0.0
Deno/Fresh:
await server.listen({ hostname: "0.0.0.0", port: 8000 });
Node/Vite/Next:
vite --host 0.0.0.0
next dev -H 0.0.0.0
3. Access URLs
| Method | Format |
|---|---|
| MagicDNS | http://<machine-name>:<port>/ |
| FQDN | http://<name>.<tailnet>.ts.net:<port>/ |
| IP | http://<tailscale-ip>:<port>/ |
Troubleshooting
| Issue | Fix |
|---|---|
| Connection refused | Bind to 0.0.0.0, not 127.0.0.1 |
| Port in use | lsof -i :<port> → kill <pid> |
| Can't resolve name | Enable MagicDNS in admin console |
| Device offline | Activate Tailscale VPN on target |
Notes
- Traffic stays within tailnet (not public)
- Target device must have Tailscale VPN active
