Get firewall OID?

Hi All!

Please anyone advice me how can we identify the firewall rule OID’s? Specifically in my case:

  1. I created the Address list to general all IPs of my country.

  2. Creating firewall rule (action = accept) to cacth total bandwidth to my address list IP above.

    Now I want to know the OID of this firewall rule to get the values of this for monitoring.
    I tried to use snmpwalk to get that but I cannot find which is the correct OID for that.

Does anyone can help me!!!
