IPFire is upgrade kernel to 5.15,so hope support more hard ware.
Raspberrypi 4B :hardware version 1.4,8GB RAM,hope full support!
Usb 3.0 Gigabit ethernet adapter :ASIX AX88179 chip,maybe also support RTL8153.
I used aarch64 flash image write to TF card,hope support 8-128GB.
I will use the Raspberrypi 4B ipfire firewall in different place for test more WI-FI
surroundings.
In this web,Hardware Revision 1.4 is currently not supported,so hope upgrade to supported.
It is 8GB RAM,I could upgrade ipfire by myself.
I used aarch64 flash image write to TF card for install,but failed.
Raspberrypi 4B is only one ethernet(lan port),so add a Usb 3.0 Gigabit ethernet adapter within ASIX AX88179 chip (wan port),need to support.
actually, it seems to be a problem of the eeprom, not of ipfire’s configuration. There is a comprehensive guide how to upgrade the eeprom to be found on this site:
You have to change your choice from ESXi-ARM-iso to Fling-on-Raspberry-Pi.pdf and download it - after checking the agreement box of course.
In the pdf, jump to 3. Preparation and follow the instructions closely - it’s too much to describe the procedure just here.
All worked well with my Raspberry 4B / 8GB…
Good luck!
By the way, I am running two different USB to gigabit ethernet adapters with my raspberry, one of it with an ASIX chip. It might be that the problem is power consumption, you should use a powered USB hub to connect the USB ethernet adapters to. They need a lot of power, especially with gigabit ethernet.
