hello
I have LAN with 100 devices, the main router is MikroTik,
everything is good, but when I make ping some of the devices showed " request time out " although it is connected and has internet.
the image below to my PC which is connected to the router via WinBox
but the ping showed " timeout "
any advice
Check firewall on clients.
I check nothing to prevent it.
thanx
Are you sure it responds to ICMP? Can you ping these from a different device?
Unfortunately, the same result
The puzzling thing is that there is a connection and I can use the printer on the network as well as the Internet
But no ping
note: many devices in the LAN have the same problem
Disable firewall on one of the machines that does not respond to ping.
If you have Windows machines, open a command prompt and run:
netsh advfirewall show allprofiles state
Make sure the results are as in the image below:
If ping works with firewall disabled, enable the firewall and create a rule to allow incoming icmp.
Unfortunately, I sure that the problem is related to the settings of the MikroTik router
I replaced the MikroTik router with another type of router, and the PING works and has no problem.
so I still looking for a solution for issues in MikroTik.
In that case, follow the hint in my automatic signature right below. Your test with another router is a sufficient proof that the firewalls on the LAN client PCs is not the reason.
You could check the Firewall on the Mikrotik Router as well, or look after packet drobs in your log.
Ther could be a rule in the outbound or Inbound chain, that cuts the traffic off.
As a second check you can preform the ping with the interface or the IP address of the router set as source address.
I didn’t know, how the router chose the source IP address if you didn’t set one, but isometimes it seams that the ping works with a set source address or Interface.
