Using 2.8.18
SNMP does not work ! doing an nmap from a machine behind the router shows its filtered below are the details. And I am using xxxxxxxx as the community name via snmpwalk and snmpget .

[admin@gatekeeper1] > snmp print
enabled: yes

[admin@gatekeeper1] > snmp comm print
# NAME ADDRESS READ-ACCESS
0 public 0.0.0.0/0 no
1 xxxxxxxx 0.0.0.0/0 yes

Any help would be appreciated.
Thanks

Probably you have level 3 and wireless installed. So remove wireless package and SNMP will work

WHAT COULD BE WRONG ?

Try this example:

to listern the SMNP from 192.168.xxx.xxx workstation which is connected to the router via the 192.168.xxx.xxx gateway
insert the gateway IP in the router SMNP setup and make sure to enable the SMNP from settings

Make sure you insert the correct mask number as well.

That should work,
Success

Are you sure your firewall rules aren't blocking the SNMP requests to UDP port 161?

Was a udp issue. Got it working. Thanks guys ! MT rocks.

what was your solution? Im having the same problems

Check there is nothing in between your machine and the router blocking of udp ports 161,162 . open everything and try. And take of wireless it will enable snmp

yeah, that doesnt seem to be a problem in my case. the mrtg server is connected directly to the MikroTik, with nothing in between. No Firewall rules that I can see that would be blocking, and I put in a passthrough statement for input and output to log SNMP traffic: traffic comes in but doesnt leave. Instead ICMP reply is sent (type 5 code 1; Redirect Datagram for the Host).

weird wild stuff
