I'm using a Fiber WAN Line at Home with a Sophos Firewall installed as Software on an ESXi 5.5.
I mostly every Day get an "Link Down" / "Link Up" Message from my Firewall (2-4 minutes down).
In the Kernel Log i always see this Line while the Link is down (IP Address Masked):

Is this because of the WAN Failure? Or is this the Cause of the WAN Failure? My ISP isn't a big help with this...
