| Composes with | composes with a host at each end and nothing else. |
| Reliability | unauthenticated by design; predates WireGuard and inherits none of its protections at the transport layer |
| Notes | Recorded because WireGuard's own documentation names it, which makes it the canonical citation for the technique rather than a candidate to deploy. It predates WireGuard and has no TLS, no authentication and no multiplexing, so the only reason to reach for it over udp2raw or wg-tcp-tunnel is simplicity. Its README was not opened; the rung says so. |
