Howto monitor OpenBSD PF firewall for performance

Packet Filter aka PF is OpenBSD's system for filtering TCP/IP traffic / NAT software. I always like the simplicity offered by PF firewall. There is a new article that explains the PF performance monitoring:

The PF (packet filter) firewall package was introduced in OpenBSD 3.0, and has since been ported to the FreeBSD and NetBSD Operating Systems. PF contains a stateful packet inspection engine, the ability to replicate state information to a backup firewall, a flexible self optimizing rule engine, QOS support, and the ability to collect performance metrics. These metrics can be useful for gauging the performance of a firewall platform, and provide a way to trend firewall performance over time. This article will describe several utilities that can be used to monitor the health and performance of a PF firewall.

On a related note you may find our FreeBSD firewall startup guide quite useful.

We used Open BSD 3.9 Firewall and are very happy with it. Our initial installer has moved to Europe and we have an opening for an experienced Tech Support person.

If this is not the right forum to declare our requirement, we apologize, and will appreciate a name contact or referral to one who could assist us.

Thanks.
