Hi! There is a RB750Gr3 (6.42.4). SNMP is on, communities configured. Dude client (Windows) connected ok, devices is discovered and on map. But services of devices (exclude ping) is down.
On try snmpwalk on device is silent and says timeout(13) on statusbar.
All firewalls are checked, the machines are in the same network and see each other perfectly. Command snmpwalk -v 2c -c public 192.168.1.1 got information.
And nc -uv 192.168.1.1 161 is succeeded.
What I do incorrect?

Just tested CHR (6.42.5). All is exellent!
What's wrong with 750Gr3? (upgtade to 6.42.5)

Can you post your snmp settings and firewall settings?
