Hi all, I have pf running on my firewall box and I'm experiencing some strange behaviour. After several hours (this may even be 24 hours) of functioning normally, pf seems to reload its default rules which means that from that point on all traffic is blocked. A simple "pfctl -f /etc/pf.conf" fixes the problem but it is very annoying.
I don't see anything relevant in /var/log/pflog or /var/log/messages but I'm not sure what I am looking for so I may have missed something. Do you have any idea why this is happening? Do you have any tips for debugging this? I'm running a stock OpenBSD 4.4. Cheers, Hilco
