Hello.
As you know, many people are now using PF on their FreeBSD servers. I've
made some changes to make it work with PF, and I think they are worth
including in the port by default.
I'm including the configuration needed to use Fail2Ban with PF on FreeBSD.
Basically, you make a table in PF, and add to the table as the
'actionban' and remove the entry from the table as the 'actionunban'.
Pretty simple.
You can easily see a list of banned addresses using:
sudo pfctl -t fail2ban -T show
Thanks for the port of this great utility!
