We have 3 sonicwalls at our 3 locations all connected using VPNs. I've recently set up Zenoss to monitor things and while I can snmpwalk the two remote sonicwalls, the one in the office where the Zenoss server is I get no response. I've enabled SNMP, set the correct community, and opened the port on the firewall, but no luck. I check the logs on the sonicwall and filter by the servers IP and all I get in every entry is UDP packet dropped. I assume this means it is still being blocked by the firewall. Does anyone have any suggestions on how to resolve this?
