Program like tracert or winmtr can only get the last hop's icmp reply

[Ben Ma]

Recently I've installed the Hyper-V components and configured a virtual switch for my network adapter. After that I found I can only got the last hop's icmp reply. All "TTL exceeded" packets are discarded. I've used wireshark to ensure the packets do arrived at the machine. I've tried to remove the virtual switch, remove Hyper-V functionality, run `netsh in ipv4 reset winsock`, and click on "Reset network" on Settings app->"Network and Internat", but none of them helped.

Here's the output of tracert:

C:\Windows\system32>tracert -d 22.16.16.1

1 * * * Request Timeout
2 * * * Request Timeout
3 1 ms 1 ms 1 ms 22.16.16.1

Wireshark file is at http://runapp.bid/icmp.pcapng

Any ideas?

IPv4 traceroute timing out all hops except last - Windows

Trace route timeout every step except last one


PS: Running Get-Netnat in powershell returns nothing.
