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