Pfsense in Proxmox and VLANs. Firewalling issues?

sensei-two

I had set up this network. pfSense ran (and still) as a VM in Proxmox, and everything worked fine:

Then, for learning purpose, I rearranged it and created VLANs.

In order to make it as simple as possible, I decided to create two VLANs only (VLAN10 and VLAN20)

I set up VLANs in pfSense first:

then I tagged a VM's network device (My Windows VM in Proxmox in this case):

For VLAN10, I set 192.168.10.0/24 as its network in pfsense and also set a dhcp server for it. Ok, it works perfectly. The Windows VM got its IP and can access internet. Great!

I got a little problem though.
From my Windows VM I can ping a PC in my real physical network, but I can ping it back from my PC.
However, I can ping the VLAN gateway 192.168.10.1 either from my external PC and from my physical external router via its terminal as well.

There must be a problem with the pfsense firewall, but I wasn't able to figure it out even though I already had set a WAN rule in pfSense

Before moving my Windows VM on VLAN10 (PRIVATE), it was in the LAN network, and I could ping it from my external physical pc, and I could even open a Remote desktop from my PC (192.168.3.100) to the Windows VM. I past-copied the LAN-net rule to create the PRIVATE-net rule, but it still doesn't work.
Could anyone help me figure why I can't ping the Windows VM from my external PC?
Thanks

This is strange. I restarted all my devices this morning, I tried it again, and it turned out that I can now open a Remote Desktop session from my external PC to my Windows VM in Proxmox in VLAN10, but I still can't ping it!

UPDATE

I FIXED IT!!

It was the Windows firewall..that bastard :-)
