Approved in the Tailscale admin console, so xtrm-unraid now shows as
"offers exit node" and appears in tailscale exit-node list. The tailnet has
two exit nodes: mikrotik-tailscale (primary) and xtrm-unraid (fallback).
Neither has been exercised from the Mac. Noted that without
--exit-node-allow-lan-access an exit node cuts the client's own LAN access,
which would break an SSH session routed over Tailscale.
