Therefore, if you happen to have some spare time, it would be interesting to check which assignment is correct (with vendor OS). When dealing with this anyway, it would also be interesting whether the device has a label MAC address.

Hi,

I haven't checked the vendor FW, I only have OpenWrt on it and would
have to flash somehow back.

The LAN MAC in OpenWrt is: 40:31:3c:02:8f:b8
The WAN MAC in OpenWrt is: 40:31:3c:02:8f:b7

The label says: 40:31:3C:02:8F:B8

In the bootlog of the vendor FW I see this:
[    7.520000] set LAN/WAN LWLLL
[    7.530000] GMAC1_MAC_ADRH -- : 0x00004031
[    7.530000] GMAC1_MAC_ADRL -- : 0x3c028fb7
[    7.530000] GDMA2_MAC_ADRH -- : 0x00004031
[    7.540000] GDMA2_MAC_ADRL -- : 0x3c028fb8
[    7.540000] eth1: ===> VirtualIF_open
