Hello Everyone,
I have a strange situation. It's not service effecting but, now that I know about it I would like to resolve it. Below is the setup with fake IP's

I have two mikrotik routers. Router A IP is 11.0.0.10 and Router B is 11.0.0.11. They are both on the same subnet which is a /22. The default gateway is 11.0.0.1.
Both Router A and Router B can ping the gateway and the gateway can ping both Router A and Router B successfully. The problem is that Router A cannot ping Router B. When I try to ping from Router A to Router B, i get a timeout. I've checked the ARP table on Router A when trying to ping Router B and the IP for Router B is in the table but no MAC. I tried assigning a static entry in Router A's ARP table but, that didn't work either. I've also looked at the packets via packet sniffer on Router A when trying to ping Router B and there are no ICMP packets showing up. I've made a firewall entry to allow all ICMP input traffic and this did not seem to work either. I've checked the ARP table on the default gateway and it has entries for both Router A and B. I've looked at the routing tables on both Router A and Router B and the dst address of 11.0.0.0/22 is reachable and the gateway on both routers is correct. What am I missing? I have no unusual firewall rules setup and each router can ping URL's and any client connected to either router has internet access. Any help would be greatly appreciated.

Thanks

Posting the result if the "ip export" command for both routers might help.

Try enabling at least the bottom of these 2 rules. It looks like they are currently disabled causing your test ping traffic to be dropped by the global drop further down in the rule set.
