"First packet is Invalid (Packet not in tcp window"

jblessing · ‎18-01-2016

I see multiple lines in the event log such as:

OUT: BLOCK [65] First packet is Invalid (Packet not in tcp window: TCP [192.168.1.77]:50483->[216.58.204.42]:443 on ppp3)

Odd thing is, if I switch off the device with that IP address, similar log entries occur from one of the other connected devices

Overall download speed looks fine, I am getting occasional loss of internet (but the blue light on the onehub stays up) and the internet comes back within 30 secs or so.

Any ideas
