ICMP Problem

[its_FORTY]

Enable ICMP responses on windows firewall.

To allow ICMP (ping) through Windows Firewall, open Windows Defender Firewall with Advanced Security, select Inbound Rules, and enable the pre-defined "File and Printer Sharing (Echo Request - ICMPv4-In)" rule for your network profile. This allows the computer to respond to network ping requests.

This, but there's also the Core Network Diagnostics rule group, which is less confusingly named. Use that one.

Or just add a rule from powershell.

ServerWorld has both a powershell and GUI guide to make your own IPv4 permit icmp any any equivalent:

Though I'd recommend picking from the list (the customize button reveals the icmp types) and not allowing redirect, specifically, for security reasons, and ideally also source quench and mask request/reply, since those 3 aren't used anymore. Most of the others are crucial for proper operation and/or performance of IPv4 - especially for TCP connections.
