PfBlockerNG-Devel and DNS resolver (SG-1100)

  • Hi everyone,

    I just got an SG-1100 and this is the first time I have used pfSense. Found out about pfblockerNG as well and found some very good guides online for the initial configuration. My first question is on memory utilization. When I first setup the feeds or make a minor change and save it, my RAM utilization is around 70%. About 24 hours later, I see the utilization dropped at 20-25%. Everything still seems to be working and not seeing anything in the logs to indicate otherwise. Is this normal behavior? I have set up the CRON job to run once a day, usually in the morning hours, to update the feeds.

    The main issue I have is with the DNS Resolver service. I was running into issues early on when I incorporated too many feeds. DNS just kept crashing and basically I could not use the service. Once I reduced the feeds, DNS worked much much better. Then I tried to enable the DHCP lease registration and I had to stop pfblocker to even apply the changes. Once that was resolved, DNS resolver would restart every few minutes. Once I disabled this option again, the crashes stopped. Is this a known issue? Is there a workaround?

    Thank you very much for any help you can provide.
