Trying to setup the networking side so that my VMs in Proxmox can receive packets (want to set up some game servers). Think I've messed up my routing somewhere but been at it for a couple days and can't figure it out.
My WAN port for pfsense is vmbr0 and my LAN port for my vms is vmbr1
On the firewall I can ping 1.1.1.1 but on my VMs on the LAN network it can only ping the firewall and other devices on the LAN but cannot access the internet - though once on a test client machine it did access the internet but after restarting it the internet access was lost again. I also have had intermittent access to the pfsense web portal via a machine on the LAN. DHCP also works within the LAN.
Any help would be appreciated!

- just changed the firewall IP to .254 and it now works.. as the IP was being used by the interface. VM's can now access the internet and its being forwarded as it should.
