No ping on a functional network

Hello to all,
I am stack over a strange problem.
I have a mikrotik routerboard 500 series that takes INTERNET from eth1 and distributes it to eth2 on a switch.
On the switch there are several access points coneected.
Everything works great and users login to the user manager, they have internet…etc.
When I am logged in on the network from my pc I ping all the routers. I can also manage them.
When I login to the web interface of mikrotik and try to ping from the eth2 the routers…all the packets are lost.
Only eth1 can ping the main modem witch provides INTERNET.
Can anyone explain this to me? Thank you.

maybe firewall is dropping ICMP protocol packets.

How can I figure that out?

Run /export … post the output here. Inside of ROS tags (click on select syntax in the post a reply menu)

OK, thank you here is the output
