[44net] PKTerrors.

Hi, Just been looking through https://gw.ampr.org/private/pkterrors.txt and I noticed there's entries for the external IP for the net I run. I'm running 44.131.170.0/30 with a RaspberryPi on 44.131.170.1 using IPIP with amprd, external IP address 90.155.50.1 The errors are like:     90.155.50.1      51.89.173.198        2 [19] dropped: non-44 inner source address What does this mean? And I can't seem to ping to 44.131.170.1 from the big bad internet, is this related? Thanks. Bill (M1BKF)
