Hello to all fellow ISA server masters,

I have setup ISA 2006 server in our DMZ to act as a Secure OWA server.
The Exchang OWA is working 100%, my issue is this,
The server is an HP server, I have implemented HP Insight Manager to monitor hardware issues if they should arise.
I have set up a custom rule to allow the HPSIM protocols as well as SNMP traffic to report back to my server in the protected LAN.
When I do a telent on port 161 or 162, the monitoring logs shows SNMP as Unidentified IP traffic, and completly by passes my custom rule even though I have
tried using the inbuilt SNMP protocol and creating a custom entry for it I get the same result.
This is impacting my HP server monitoring software.
Any Help on this is much appreiciated.

What does your rule state.. are you specifying UDP and/or TCP?

Have you considered sending your traps thru an SSH tunnel instead (e.g. using OpensSSH) and opening up Port 22/TCP? SNMP thru firewalls is often frowned upon for being insecure.
