DNSBL Webserver Interface
In pfB, this setting allows me to select one interface. It's setting description is "Select the interface you want the DNSBL Web Server to Listen on". What exactly is this for? If I have multiple interfaces (several VLANs), then what do I choose?
This just defines what interface to bind the DNSBL Webserver to. You can just use LAN.
If you have VLANs, then select the DNSBL Permit Rule option and select the Interfaces that should be allowed to hit the DNSBL webserver address. This will create a Floating Permit rule with those settings.
