Can the Proxmox host connect to it's pfsense VM for network/routing or do I need an external network too?

[IMTheNachoMan]

I have a computer I was going to put Proxmox on and then a pfsense VM for FW/routing.

I know that I can bridge the Proxmox host's two ethernet ports to its pfsense VM so all of my external devices (computer, AP, printer, etc...) will get network/internet through the pfsense VM on the Proxmox host.

But I'm at a loss for two things:

1. How will the Proxmox host get network such that I can access Proxmox's web interface from another computer?
2. How will other VMs on the Proxmox host get networking/internet? They'd have to some how connect to a NIC linked to the pfsense VM -- right?

It seems to me that #1 isn't possible -- chicken and egg. Or am I missing something?

You can create 2 bridges in PVE and 2 NICs for the pfSense VM.
1 bridge goes to the ethernet port that goes outwards/to your modem. There you attach the pfSense WAN.
1 bridge goes to the ethernet port that goes to your switch. You attach this to the pfSense LAN and you give this bridge an IP like

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.10.2
        netmask 255.255.255.0
        gateway 192.168.10.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

and then you can attach VMs to the bridge and other devices to the switch and they are in the same network.
