pfBlocker setup question?

[Velcro]

Just installed pfBlockerNG and had some basic questions, my set up is as follows:

*2 VLANs (1&2)
*My rules force all traffic is forced thru PIA Interface(setup with OpenVPN) including DNS and ports 80/443
*My rules are using "PIA Intreface" as the gateway
*I am using Quad9 in addition to pfBlockerNG

My questions:

1. Firewall -> pfBlockerNG -> IP tab:

Inbound Firewall Rules - are on "WAN" and "PIA Interface"...do I need to select "OpenVPN" ?

Outbound Firewall Rules - My 2 VLAN that I want blocked are selected here. Is this correct?

2. Firewall -> pfBlockerNG -> DNSBL tab:

Webserver Interface = VLAN 1(Default LAN)

DNSBL Configuration->Permit Firewall Rulles = VLAN1. I am trying to protect my LAN and certainly do not want my VLANs to talk to each other. Is this OK to use VLAN 1 or is there another best practice? My LAN has no internet access.

Thank you again for any help or guidance...
