Firewall Stats VIA SNMP
I was wondering if anyone knew the OID or of another way to monitor details about the firewall like blocked packets or passed packets, connections through the firewall, etc.
Even a way to make graphs like munin would be appreciated: http://demo.munin-monitoring.org/cgi-bin/munin-cgi-graph/localdomain/localhost.localdomain/fw_conntrack-day.png
Have a look at the pf MIB, should have all the answers.
