freenas.local security run output (is my nas being compromised?)

[Cyberax]

Hi

I have been running a freenas server for quite some time now and it has been working flawlessly

now this has been showing up in my daily security run output

My Nas is currently connected to the net so that it can retrieve plex media metadata just through a dsl/firewall router combo

in the future I may add an additional firewall like untangle


Is there any reason for concern??

any suggestions are welcome

I think something was just trying to change ip entry.. I don't think your compromised.. Just find what device is using that MAC..
