I just upgraded to Kerio Control 8.3.0 and when I look in the "Hosts" log, I see the following 2 entries repeated every 5 - 30 seconds:
[26/Apr/2014 14:13:17] [IPv4] X.X.X.X [MAC] YY-YY-YY-YY-YY-01 (Company Name 1) [Hostname] MyPC - MAC address changed from YY-YY-YY-YY-YY-02
[26/Apr/2014 14:13:33] [IPv4] X.X.X.X [MAC] YY-YY-YY-YY-YY-02 (Company Name 2) [Hostname] MyPC - MAC address changed from YY-YY-YY-YY-YY-01
The IPv4 address and Hostname are always the same (and correct for MyPC which located on the local trusted network). MAC address YY-YY-YY-YY-YY-01 is the correct one for MyPC and YY-YY-YY-YY-YY-02 is the MAC address of the Internet Interface on the Kerio Control Machine (which is a dedicated machine running the Software Appliance).
Any ideas why this is happening? I have some outside traffic that gets forwarded to MyPC and that DOES appear to be working.

Update: I now have a different computer on the network that is logging a MAC address change from its actual MAC address to the same Internet Interface MAC address mentioned above. The original computer mentioned above is also still report the same MAC address changes (every 5-30 seconds). The new additional computer doesn't seem to do it as often.
