Hi! Today, I wanted to share that I recently turned my raspberry pi into to a firewall to make it part of my home lab. Here are some notes for setting up IPFire on raspberry pi. When I was setting up IPFire, I got stuck for a little while with a rainbow screen when trying to boot it up.
1. Set "hdmi_safe" to 0 which you will find in config.txt.
hdmi_safe=0
2. Set "SERIAL-CONSOLE" to OFF which you will find in uENV.txt.
SERIAL-CONSOLE=OFF
Hope it helps if any one of you encounters the same issue. Firewall is something that I haven't really looked into and excited about adding new component into my home lab and learning what it is capable of!
