Newbi here also

[timlab55]

Okay, I'm completely lost when it comes to this stuff.  So please bear with me as I ask my questions.  My setup is as follows:  1GB fiber coming into my ATT Gateway (320-500).  From the ATT Gateway, I have it in IP Passthrough mode to my ASUS RT-88U Pro.  Now here's comes the fun part.  I would like to use my raspberry PI4 for OPNsense.  So how would I wire this up?  Can it even be done?  What is the best way of doing this?
Thanks

I believe that's there's a topic about this (https://forum.opnsense.org/index.php?topic=35828.45) but I suspect it's not for newbies.

IMO, save yourself the trouble and try it out on a mini-PC with at least 2 Intel NICs.

Your right that's over my head.  As I said "I'm a newbi".

Dont use a Raspi for OPNsense. If you want something that just works, get an official appliance from the OPNsense shop. Otherwise use a mini PC with an intel N100 CPU and Intel Network Ports.
