I can ping PFSense but PFSense can't ping back

If I had to guess it was some sort of attempt at allowing wol from wan?

I know this topic is quite old, but it was the only one I could find that had my exact issue. In my case I accidentally enabled the Proxmox firewall on the VM I was trying to ping, so make sure to double check if you enabled a firewall, it could have saved my multiple hours of headache...
