I have a completely puzzling issue. Hope someone can help me solve it. My local network contains 2 MikroTik devices - HAP AC2 as a router with the Dude server installed and RB951G-2HnD as a range extender. No matter what, I cannot make the Dude to monitor system resources (CPU, memory, disk) on the router. SnmpWalk works fine works fine when polled from the range extender or from Windows shell tool, but doesn't when polled from the router itself; regardless of what is selected as agent (default, router, range extender); all system services are always reported down and all SNMP tabs in the Dude device settings remain empty. I tried both SNMP V1 and V2 but to no avail.
I'm quite a newbie in MikroTik, so there is a chance I've overlooked something basic, like a firewall rule or some bridge settings, so I'd appreciate any help.
