I just tried booting the 13.1-RC4 candidate on my Pi3 from microSD. It exhibits the same strange "no response to inbound ping" as before. It does seem to set time successfully using ntp, and outbound ping works fine. Inbound ping from both the same (public) network and across a NAT link from my LAN work very poorly. The NAT'd link shows 92% packet loss, the direct link around 88% loss. The USB devices present are an FTDI232 and an ASMT usb-sata bridge, neither is in active use. Inbound ssh connections time out, even with outbound ping running and getting answers. Not even a password prompt. It's hard to believe I'm the only one seeing this...... Thanks for reading, bob prohaska
