Hello!
I recently install the Dude3.6 for monitoring my network.(on RouterOS)
Network has more than 7k active devices, which monitoring via ICMP,SNMP,SysLog.

When count of devices in Dude was more then 300-400 - Dude was start a strangely.
Devices and links, which all time check all SNMP parameters and send to hints, labels, etc... has stopped getting SNMP parameters, and said about "timeout" when i try snmpwalk from server to devices. While the earlier that devices get parameters are correct. On my workstation snmpwalk passes without problems.
BTW Dude plugged in network 192.168.200.0/24 also my workstation plugged in this network and NAT on same ext interface.
When i look dump and snmp statistic on Juniper ex4200 requests and answer from and to Dude server are passed (Dude said that no). All rules and ACLs are correct.

I really need snmp for fast determine of type of devices, their parameters and creating correctly schemes by physical interfaces, vlans and networks. Whithout thats features...not serious solution.

HMP!

This is fixed in 4beta2.
