If you have ping but no snmp, that means the mikrotik is filtering it at some place.

Also, there was an old bug where mikrotik replied from different IP than the polled one, so snmp were not working properly.

That being said, I have a few mikrotik devices that stopped replying snmp from one day to other and I was unable to find/fix the problem. Shame on mikrotik :rofl:

ty for the responce im trying to get this to work, snmpwalks to that mikrotik device are still timing out :cry: im going crazy

i solve the issue by adding this rule on my core mikrotik device by adding this firewall rule

but adding the same rule on my distribution mikrotik devices doesnt seems to work

nmap shows the following

maybe the rule needs some change on the other devices…
any ideas?
