No issues with WFC, but looks like windows firewall in win10 is buggy. I have a LAN rule I carried across it basically allows traffic to/from lan subnets which saves me making rules for services/apps that only get used for lan traffic. On win8 no issues, on win10 it works but occasionally a packet gets blocked randomly in the firewall, I notice as of course it triggers a notification, it happened just now with me sat at PC, winNUT lost connection to my router when was blocked, but then the windows firewall a minute later allowed it to connection again. -- After looking at the event log, I can see "An account was successfully logged on" entry, and also can see the windows firewall momentarily switching to public profile and then back again to private, that is why the rule didnt do anything as its on private profile only, but the mystery left as to why the mode got changed. The logon type was 5, A service starting up. Then same again very shortly after for back to private. This was logged in system log at same time, getting closer.
