Please post more information (e.g. /etc/network/interfaces
, the /etc/pve/qemu-server/<vmid>.conf
of your pfSense VM, maybe ip a
output, etc...).
In general, making your PVE instance available only through a pfSense VM that's hosted on there is a recipe for trouble, since you won't be able to remotely fix any issues with your VM if it ever happens to crash. Physical access is a must for such a configuration.
