I struggle getting SNMP to work on my WAN interface (that is from the Internet and towards my Mikrotik Routerboard that acts as both a router and firewall on my home network. If I run , I get the following output (non-relevant rules are removed): Also, to ensure that SNMP is activated, I run this command that returns: When I try to test the connection, by running there is no response - but even stranger, the firewall (if I look at the rules in WinBox) indicates that NO packets are detected on the rule I created!

I suspect that my ISP could be blocking UDP/161 from the internet and towards my home network, but to my knowledge I cannot verify this unless I disconnect the Mikrotik router and connect the WAN port to my computer to remove the ISP from the equation. Is there another way I can troubleshoot this?

Yes, there is another to troubleshoot it. Create a VPN to the router and re-test. That will take the ISP out of the equation.

Hi, thanks for the reply.

That was a good idea, but I did not have to go for that option. I sent an email to my ISP and asked if UDP/161 was blocked, and they replied that it was because they had detected a security issue with the standard router they sent out to their customers. Once I explained to them that I did not use the standard router, but a Routerboard, they opened the port.
