I am trying to detect problems on hosts in my network : I want to detect when a communication occurs with a compromised host. I have built a blacklist which holds near 2 millions ip (spam, malware.... hosts).

But I can't load it into pf, I get this when I try :

     /etc/pf.conf:6: cannot define table bl: Cannot allocate memory
     pfctl: Syntax error in config file: pf rules not loaded

I suspect there is a memory limitation somewhere (in the kernel ??) which prevent me from loading the table but I am not very comfortable with kernel variables. I have already try modifying kern.maxssiz and kern.dflsiz without success.

Any idea?
