snmpget OK but CACTI NO (No SNMP data returned)

[rafuchoucv]

Hello Friends.

I have a newly installed CACTI on windows that was working OK with the Default computer and a test Sonicwall on my own LAN. I tried to monitor the SNMP - Interfaces for another SonicWALL outside of my network but I'm having some weird results.

I can get the Basic info (uptime, contact, name) OK, but when I try to get the SNMP - Interfaces info, I get this:

Total: 0.000000, Delta: 0.000000, Found data query XML file at 'C:/Apache24/htdocs/cacti/resource/snmp_queries/interface.xml'

Total: 5.550000, Delta: 0.000000, No SNMP data returned

I was thinking that maybe some firewall or nat or something in the middle was causing the issue, but if I run snmpget from the same computer to the same device I get:

snmpget -v 2c -c hidden X.X.X.75 .1.3.6.1.2.1.2.1.0
IF-MIB::ifNumber.0 = INTEGER: 9

The same command ran against the SonicWall that is running fine show:

C:\Users\rafael>snmpget -v 2c -c hidden X.X.X.1 .1.3.6.1.2.1.2.1.0
IF-MIB::ifNumber.0 = INTEGER: 15

So why .75 SonicWall is failing to gather data from the interface but is answering just fine on the SnmpGet, I checked community name on Cacti and is OK, what else can I check?

This is the debug response from the .1 firewall (the one OK) for SNMP - Interfaces

When I was posting this question I notice the time difference for both debug logs were important, so I started to test many options for threads and SNMP timeout and I found this was the issue, I'm going to left the post in case it help someone else.
