IPIP6 Protocol Not Appearing in Network Interface List after Package Installation

I recently installed an IPIP6 protocol package for OpenWRT, hoping to see it appear in the network interface protocol list. However, it doesn't seem to show up after installation, even though the scripts seem correct.
The package is here HiraokaHyperTools/openwrt-ipip6 (github.com), and my openwrt version is OpenWrt R23.3.3 GDQ V1[2023] Compiled by eSir / LuCI Master (git-23.082.27304-adda8b2)

I've verified that the scripts are placed in the correct directories, have the necessary execution permissions, and I don't see any errors related to these scripts in the system logs. I've also tried clearing the Luci cache without success.
Has anyone encountered this issue before or could provide some guidance on troubleshooting this? Any help would be greatly appreciated.
Thank you in advance!

Welcome to the community!

This seems to be @kenjiuno's GitHub - tagging him.

This isn't an official OpenWrt build BTW - not sure how we can assist.


Just to provide some background information, as neither your running firmware, nor the package you're asking about are OpenWrt - there really is very little (~= nothing) we could help you with.

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.
