Hello, there!
I spended a lot time for debug network problem with an host from my localnet. Testing it host via tool “Ping” in app “Mikrotik” (v.1.2.17 and v.1.2.18) on iOS and got always “Timeout”. And checked all level OSI. Then I testing all hosts my network from it tool, and got "Timeout". Only gateway pinged properly. Then I run “Winbox” (v.4.0beta33) on Windows 11 and use the same tool “Ping” and it ping problem host properly! And other host my net too! What’s it? How-it work? What I did not it?
