What are the differences between the Mini Appliance and PC Engines APU4d4


I understand that the Mini Appliance is based on the APU4d4 but has undergone some modifications. Can anyone describe those modifications or what the differences are?

I don’t need 4 x NICs and so was looking at the APU2e4 as it has 3 x NICs and uses what I understand are slightly better i210AT NICs. I am intending to just configure RED and GREEN interfaces, as I plan to to run my internal network entirely from a managed switch, including my UniFi APs. I am a home user so don’t have any public facing equipment that would require an ORANGE interface.

Also, I want to establish three or four VLANs inside my network and I understand that this is easier to do from a managed switch, vice trying to configure them from the firewall with a maximum of one VLAN per NIC within IPFire.

I am very new to this and have yet to purchase any hardware. I haven’t used IPFire or any other firewall OS (I am also considering OPNSense) so my comments above may be incorrect.

Thank you.
