Question #1121
How do I access SNMP servers like MRTG from the ISA Server firewall itself?
Answer
No problem! Stefaan Pouseele has the answer for you here:
So, to access an external SNMP resource (no trap) you need the following packet filters:
Packet Filter 1:
Packet Filter Name : SNMP over TCP
Enabled : True
Filter Mode : Allow
Filter Type : Custom
Protocol : TCP
Direction : outbound
Local Port : Dynamic Port
Remote Port : 161
Packet Filter 2:
Packet Filter Name : SNMP over UDP
Enabled : True
Filter Mode : Allow
Filter Type : Custom
Protocol : UDP
Direction : send receive
Local Port : Dynamic Port
Remote Port : 161
