GL-MT6000: ling WED breaks NAT hairpinning only on wired connections

Hi,
I've noticed that enabling WED on my GL-MT6000 (OpenWrt 23.05.4, r24012-d8dd03c46f) breaks NAT hairpinning only on wired connections.

Disabling it fixes everything.
I've also opened an issue at https://github.com/openwrt/mt76/issues/903, with no reply yet...

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
