Keeping your /var/log/pflog file clean and managable
When you use pf with a default policy of block log all you will quickly find the /var/log/pflog being filled with for example DHCP traffic and NetBIOS broadcasts.
To keep this file clean and managable, you can use a simple technique. To understand this method you have to keep in mind the two characteristics of pf that are mentioned in pf.conf(5):
By inserting a block quick without log, before the default block log all policy, we block the unwanted traffic. Any other traffic will be blocked but also logged.
Some practical examples of applying this technique:
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
