UTM MIB

Hello,

I'm looking to monitor out firewalls with snmp.

I've configured SNMP in the firewall but when I try to read some values it get No data available in this subtree.

Donwloaded the mib from the firewall itself and imported it into MIB browser

example : .1.3.6.1.4.1.9789.1500.1.20

it seems that OID .1.3.6.1.4.1.9789 doesn't exist anymore.

Can someone give me the correct OID?
