Add a VM-based natlab test that exercises the peer-relay feature (feature/relayserver) end-to-end across three Tailscale nodes whose network topology makes a direct A<->B UDP path impossible: both peers are behind HardNAT (FreeBSD/pfSense-style endpoint-dependent NAT) with no port-mapping services, while the relay node is behind One2OneNAT so its STUN-discovered WAN endpoint is reachable from both peers. The test enables the relay server via EditPrefs, then waits for an a->b PingDisco whose PingResult.PeerRelay is set (proving magicsock chose the peer-relay path, not DERP), and finally asserts that the relay's DebugPeerRelaySessions LocalAPI reports the session. The existing TestPeerRelayPing in tstest/integration runs three tailscaled processes on the loopback interface with no NATs; this new vmtest covers peer relay through real per-VM kernels and NATs. To wire control-server capabilities into vmtest, also add a PeerRelayGrants() EnvOption (sibling of AllOnline, SameTailnetUser) that flips testcontrol.Server.PeerRelayGrants so the wildcard packet filter grants tailcfg.PeerCapabilityRelay and PeerCapabilityRelayTarget; without those caps magicsock won't consider any peer a candidate relay.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
