      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!

          It's not that. It looks like a missing uboot env in that case. On the SG-1100 that does not prevent it booting and running normally. However if you open a ticket with us we can get that fixed for you.
