You're dealing with a network issue where communication between certain devices isn't working as expected. It seems the path from one subnet to another is broken or blocked. Check the routing tables and ensure there are no misconfigurations that prevent traffic flow between those ranges. Also, verify firewall rules or ACLs that might be blocking the necessary packets.
Though? Data can flow in either way and a third party can reply to pings, which means a firewall shouldn't be the problem. No antivirus software is running.
Windows Firewall occasionally blocks ICMP packets from what it thinks is an external network. Consider turning it off briefly to check the issue.
You can adjust the filtering rules to allow specific traffic while keeping the firewall enabled.
Consider this an inbound configuration. It should appear under File and Printer Sharing. Try it out: Open Advanced Settings on the left, then click Inbound Rules. In the right panel, locate the rules named File and Printer Sharing (Echo Request - ICMPv4-In). Right-click each and select Enable Rule. Let me know if it functions as expected.
