Hi!
I'm new here and a bit desperate with an exercise I have on hand. The exercise consists of the following:
Using VirtualBox, we have to create:
A WAN network (where a machine will be, in this case, Kali)
A LAN network (where another machine will be, and which the Kali machine can also connect to)
A DMZ network (where a Metasploitable machine will be, and which the Kali machine can also connect to)
The idea, evidently, is as follows:
From the WAN: be able to communicate with the DMZ, but not with the LAN.
From the LAN: be able to communicate with both the WAN and the DMZ.
From the DMZ: be able to communicate with the WAN, but not with the LAN.
So, in VirtualBox, I configured three interfaces, one for each of the networks. The only peculiarity is that both the LAN and the DMZ have the DHCP server disabled, as I manually configured their IPs:
LAN: 10.0.3.x
DMZ: 10.0.2.x
WAN: 10.0.4.x
In the Firewall rules, I have configured the following (the version of pfSense I am using is 2.7.2):

When testing with ping, everything works as it should, except when I reach the WAN and try to ping the DMZ. In this case, I get no response, and I don't know why. Any ideas? Is there something wrong with the rules? Should I check something else? I'm quite new to all this, so I'm a bit lost.
Thank you very much!
