Increase Firewall Maximum Table Entries

Navigate to System → Advanced → Firewall & NAT.

In Firewall Advanced:

  • Firewall Maximum Table Entries: Set to at least 1000000, unless the system has very little RAM.

NOTE: Without increasing this value, DNS queries take much longer, causing webpages to load very slowly.

As a rough guide, set this value to the following, depending on how much memory there is.

MemoryFirewall Maximum Table Entries
4GB800000
8GB1000000
16GB1200000
32GB or Higher2000000

If lots of blocklists are being used, then look at setting these slightly higher if you notice any slowness in DNS resolving.

  • Be careful of setting this too high as it directly uses more RAM the higher you set it.

Return to Install pfBlockerNG or continue to Install pfBlockerNG Package.
