Reworks the page around what most users should do, instead of leading with the hardest option.

  • All routes are now content tabs, easiest first: Tailscale, Cloudflare Tunnel, HomeKit (via the Home Assistant HomeKit Bridge or Homebridge), Caddy, nginx, Traefik.
  • The old page mentioned VPNs in one tip line and then only documented a reverse proxy. Tailscale is now a full walkthrough (subnet router on an always-on device), since it's the least setup and exposes nothing to the public internet.
  • Caddy example updated: basic_auth (renamed in Caddy 2.8), a subdomain vhost instead of the /wled/ path-strip pattern, and both 80 and 443 forwarded. The old "only requires port 443" claim doesn't match Caddy's docs, which want both ports for the ACME challenges and the HTTP redirect.
  • nginx and Traefik examples added, including the WebSocket upgrade headers nginx needs for the live view (/ws).
  • Kept: the port-forwarding warning and the OTA lock recommendation (now a tip admonition).

Commands and claims were checked against the current Tailscale, Cloudflare, Caddy, nginx, Traefik, and Apple documentation.

Summary by CodeRabbit

  • Documentation
    • Reworked the remote-access guide with secure options including Tailscale, Cloudflare Tunnel with Access, HomeKit, Caddy, nginx, and Traefik.
    • Added setup guidance for authentication, HTTPS, WebSocket proxying, route-specific configuration, and OTA Lock.
    • Clarified secure Tailscale routing, including full LAN subnet advertisement.
    • Added Cloudflare Access setup details and emphasized changing the default OTA Lock passphrase.
    • Clarified that Home Assistant supports remote access when securely reachable.

Walkthrough

The remote-access guide documents Tailscale, Cloudflare Tunnel, HomeKit, Caddy, nginx, and Traefik. It adds authentication, HTTPS, WebSocket proxy settings, route-specific setup, and OTA Lock configuration.

Changes

Secure remote access

Layer / File(s) Summary
Remote-access route selection
docs/advanced/access-over-internet.md
The guide adds route selection guidance and instructions for Tailscale, Cloudflare Tunnel with Cloudflare Access, and HomeKit.
Authenticated proxy configurations
docs/advanced/access-over-internet.md
The guide adds HTTPS and authentication examples for Caddy, nginx, and Traefik. The nginx example includes WebSocket proxy headers.
OTA lock requirement
docs/advanced/access-over-internet.md
The guide requires OTA Lock activation and replacement of the default wledota passphrase.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 6ab53

The documentation still includes a command that exposes plaintext passwords, a certificate setup that can fail renewal when only HTTPS is forwarded, and an nginx WebSocket configuration that may disconnect idle live views; these bounded security and availability risks should be fixed or explicitly accepted before merge.

Suggested reviewers: netmindz, willmmiles

Poem

A rabbit checks each route with care,
HTTPS protects the tunnel there.
Tailscale, proxies, HomeKit flow,
While OTA locks guard the show.
Secure WLED paths now appear—
Hop safely through the year!

In `@docs/advanced/access-over-internet.md`:
- Around line 139-140: Update the “Enable the OTA lock” tip to explicitly
require enabling OTA Lock and changing the default wledota password to a
non-default value. Describe the protection as blocking Wi-Fi OTA updates, rather
than claiming it prevents every possible firmware replacement.
- Line 33: Add Linux client route acceptance guidance to the Tailscale access
instructions: document running `sudo tailscale set --accept-routes=true` on the
Linux laptop before accessing WLED through the advertised subnet route. Keep the
existing phone and `.ts.net` guidance unchanged.
- Around line 44-46: Reorder the Cloudflare setup steps so the Access
application and its allow-only policy for the hostname are created before
configuring the tunnel’s public hostname route. Preserve the existing hostname
example and one-time PIN policy, then add the route to the WLED service only
after Access protection is in place.
- Around line 21-23: Update the Tailscale setup sequence after installing
Tailscale on the always-on home device to run sudo tailscale up and complete
device authentication before the advertise-routes command. Keep the existing
subnet adjustment guidance and ensure tailscale set is presented only after
authentication.
- Around line 23-31: Update the Tailscale route example to advertise only the
WLED host using a /32 placeholder instead of the entire LAN /24 subnet, and add
documentation for a corresponding Tailscale grant or ACL restricting access to
that WLED host.

Document the ACME challenge and required network access.

Set an explicit WebSocket read timeout.

nginx defaults proxy_read_timeout to 60 seconds. WLED does not send a periodic server heartbeat, so an idle /ws connection can close. Add proxy_read_timeout 1h; or document a client heartbeat and reconnect strategy.

Constrain the One-Time PIN policy to the intended email.

Add an explicit Tailscale grant or ACL.

Route approval only controls route injection. It does not authorize traffic. Because this example advertises 192.168.1.0/24, any identity permitted by the effective policy could reach the LAN range. Add a grant or ACL for the intended user or device and the WLED destination. Tailscale documents routing and access control as separate requirements. (tailscale.com)

This comment repeats the unresolved access-policy concern from the previous review. The /24 route is intentionally retained by this PR, so the access policy is required.

Enable IP forwarding before advertising the subnet route, matching
Tailscale's subnet router guide.

Say the Cloudflare Access policy should allow your own email address. A
policy that names only the login method lets in anyone who can receive a
