Hello,
For some reason, BD has started blocking incoming ICMP / ping requestson my Windows 7 PC from other machines on my Home LAN.
I have checked Settings ->Firewall -> General Rules ->Incoming ICMPv4 / ICMPv6 is set to Allow.
I have also checked that Firewall -> Manage Adapters -> Network Type is set to Home/Office.
I can ping other machines on my Home LAN from the PC.
I don't know if this is relevant, but I have recently configured this PC as an OpenVPN client to access a remote VPN server.
I confirm that the VPN session is disconnected before trying to ping the machine from the other device.
