Brad Fitzpatrick 0a5ab533c1 net/netcheck: send dummy packet out to help airport extreme in hairpin check At least the Apple Airport Extreme doesn't allow hairpin sends from a private socket until it's seen traffic from that src IP:port to something else out on the internet. See https://github.com/tailscale/tailscale/issues/188#issuecomment-600728643 And it seems that even sending to a likely-filtered RFC 5737 documentation-only IPv4 range is enough to set up the mapping. So do that for now. In the future we might want to classify networks that do and don't require this separately. But for now help it. I've confirmed that this is enough to fix the hairpin check on Avery's home network, even using the RFC 5737 IP. Fixes #188		4 years ago

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale code. It currently includes the Linux client.

The Linux client is currently cmd/relaynode, but will soon be replaced by cmd/tailscaled.

Using

We serve packages for a variety of distros at https://pkgs.tailscale.com .

Building

go install tailscale.com/cmd/tailscale{,d}

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.14) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.
