Hi everybody, I have a Guest I have an pfsenseMV with two network adapters configured one NAT and another with internal network, everything works fine I have Internet access but when I intend to do forwarding port in the Adapated NAT it does not work, it only works if I disable the internal network adapter.

Does anyone know why that happens? and how can I solve it so that it works with the two enabled adapters

My host is Manjaro anb VirtualBox ver 5.2.18

Help Please!
This is my configuration
