OpenWrt and Pfsense on VM proxmox

Hi everyone, assuming I've never used Openwrt,
I have a 1Gb FTTH connection in pppoe, in practice I would like to install openwrt on proxmox to manage the pppoe connection and then pass the traffic to pfsense, always installed on a VM.
how many tabs should i add openwrt? how should I then connect openwrt to pfsense?
Thank you

Why? Pfsense and openwrt are both border routers and both support pppoe - why would you want to use them together on the same hypervisor?

because pfsense uses only one heart for the PPPoe, since the connection is 1Gb it cannot provide all the speed
