It is not recommended to use a pfsense firewall with multi lab port as you would normally use a router you buy.
If you are aiming to connect many computers directly to the pfsense firewall, as said you shouldn't do that.
The guide here https://nguvu.org/pfsense/pfsense-baseline-setup/
Shows you how the firewall ports should be setup.
The guide shows VLAN setting but they work exactly as they are normal port.
I initially wanted to do what you are trying to do but then, after reading I followed the guide setting up only the vl20_VPN port and the VL30_clearnet one as backup if i will want to bypass the VPN.
I then use a standard wireless router plugged to the vl20 port and all my devices connects to the wireless router.
If I want to bypass the VPN, I just swap the cable connecting the pfsense to the router using the cable going out from the VL30_clearnet port
