Check IP status (online/offline) behind NAT

RouterOS General
1

Hi all,

so let’s assume situation:

Testing PC (IP: 10.10.10.10) → MikroTik (NAT, Firewall) → LAN {PC1 (IP: 192.168.1.10), PC2 (IP: …11), PC3, PC4}

All I need is check from testing PC whether given IP in LAN (behind NAT) is online or not. I can’t do that with ping, right? (I can ping only router’s outer interface.) Is there any other way to check IP status of any machine inside LAN behind MikroTik router using NAT & firewall from Testing PC? (Perhaps through IP forwarding?) Thanks in advance.

It is possible only when a connection established behind of NAT
( I think << may i make mistake >> the Microsoft calling it Secure NAT for this reason ).
when you are using NAT (overlay NAT), there’s do PAT too. for example 192.168.X.Y are using Z.Z.Z.Z:abcd to connect over the net, when you now which abcd are mapping to 192.168.X.Y, then may you can do something, Perhaps may
