SG1100 : MAC address changed after upgrade from 2.4.5-p1 to 21.02

[Rod21]

Hi,
For a reason that I can't explain, my SG1100 changed its MAC address after the upgrade from 2.4.5-p1 to 21.02. Before the upgrade, its MAC address was the real one (starting with f0:ad:4e ...), and then after the upgrade the MAC address is spoofed and starts with 00:51:82 ... I discovered the problem because my WAN interface receives an IP from a DHCP server with permanent lease. I fixed the problem with a static IP on WAN interface but I wanted to know if other people had had the same problem.

@rod21 I am seeing something potentially related now over at my thread here. In my case it's actually the stuff behind the firewall leaking out of the WAN!
