LuCI Installation

This documentation is still being edited and may differ from the actual version.

This is the recommended path for most users and does not require SSH. Complete the pre-install network check first. At this point, the OpenWrt router itself should be able to reach IPv6 package feeds; client devices may still have no normal connectivity until Flet’H is installed and configured.

1. Add the public key

Section titled “1. Add the public key”
  1. Open LuCI.
  2. Open システム -> 管理 -> リポジトリの公開鍵.
  3. Paste the following key into the public-key input box near the bottom.
  4. Click 公開鍵を追加.

-----END PUBLIC KEY-----

Completion check: LuCI shows no error, and the newly added key appears in the key list.

2. Add the custom feed

Section titled “2. Add the custom feed”
  1. Open the LuCI web interface.
  2. Open システム -> ソフトウェア.
  3. Click apk を構成.
  4. Add this line to /etc/apk/repositories.d/customfeeds.list.
  5. Click 保存.

Completion check: the dialog closes and the software page is shown again with the configuration saved.

3. Update the package list

Section titled “3. Update the package list”
  1. In システム -> ソフトウェア, click リストを更新….

If list update fails, return to the pre-install network check and confirm that wan6 lets the router itself reach IPv6.

Completion check: the package list refresh finishes without download or signature errors.

4. Install luci-proto-fleth

Section titled “4. Install luci-proto-fleth”
  1. Search for luci-proto-fleth in the filter box.
  2. Install the package.

If installation fails, confirm that the package list update in the previous step completed successfully.

5. Check after installation

Section titled “5. Check after installation”

Refresh LuCI and confirm that you can see:

  • Network -> Flet'H
  • Flet'H IPoE in Network -> Interfaces
  • If static IP components are installed, Flet'H Static IP or Flet'H Static IP (Passthrough)

If LuCI does not change after installation, clear the browser cache or log in again.

The screenshots and paths above are for the OpenWrt 25.12 apk setup. If you use OpenWrt 24.10 or earlier, or if you want the complete package-feed details, see dl.fleth.link.
