Gargoyle 1.15.x nftables EXPERIMENTAL BETA - 2025-05-13

[Lantis]

Gargoyle 1.15.x nftables is an EXPERIMENTAL BETA switching Gargoyle from firewall3 (iptables) to firewall4 (nftables). This is a large rewrite of significant portions of the Gargoyle firewall infrastructure and is therefore prone to bugs being introduced.
Please keep in mind that while I need your feedback, I cannot guarantee this as a stable release, and should only be tested by the adventurous and/or those who are willing to troubleshoot and/or rollback to a previous firmware.
The fantastic news is that this release is 100% configuration compatible with the 1.15.x releases in this thread, so you can move back and forth between them as you wish.

This work is a stepping stone to then move to OpenWrt 24.10 based builds, so it is important to get this right and get it finalised.

Configs should generally not be preserved between 1.14 (and earlier) and 1.15.x. Do so at your own risk.

Please provide your feedback (positive or negative). If you do think you've found a problem it would be incredibly helpful if you also verified that the problem did not exist on the firewall3 1.15.x builds. I'm happy to fix bugs that also existed there, but will be focusing on regressions first.

As a vote of confidence, I've been running this build on my main router at home for several days without incident.

Same, testing since a few days on Archer C7 V2, no problems.
