New Around Here
Hello all, I have had two Asus firewalls RT-AX92U and the RT-AX96U. I would like to work on creating a completely back to basics router with a firewall. None of the add-ons. My dream would be only to have or include the following to this firmware-slim.
I would keep the following based on the ASUS Factory pages
Wireless MAC Filter
Roaming Block List


Internet Connection
Dual WAN
Port Trigger
(Port forwarding allows multiple devices to share a single open port and port trigger only allows one client at a time to access the open port.)
and/or Virtual Server-Port Forwarding



Firmware Upgrade
Restore/Save/Upload Settings

That is it. I turn every single other thing off on my routers every time. I don't use and turn off everything below so I would even like to remove the code and services completely. If anything is needed, I would run a ssh session into the device and with a batch.sh the service on like httpd and only that one service like logging. I would know that I would have no data except waiting for a few minutes for live data to start logging in. Then turn the service off with a script and httpd off. Slim slim slim slim slim. Did I say small, tiny? Yes like the good old days.

Here is everything I would remove from this firmware in no order at all. And yes I would be blind. No fancy graphs or logs. No Antivirus and no VPN. But I have other tools I can manually install and compile locally to see what's going on when I need to on each of my devices. I can move devices behind this firewall where I would secure them from this. This front end would be mainly for my Playstation only. I have a new echo devices, A few Tablets, and a few TV's that connect. That is it. I don't have millions or even thousand of dollars to my name so nothing I am going to lose is going to hurt me except my emails were compromised or I can't log into social media. Oh no! End of the world. My credit is so bad that I can't even open a credit card or even think about buying a house or a car,. So not the End of the world. Not for me. (Too personal but no big deal)

Is this even possible to make something like this. I'm starting to download the files now and working with Multipass building now on my Mac. Should I just stop this thought and forget about it or what can I do to make the lightest firmware build ever? Imaging how jslinux running with 1mb of ram light but this is what inspired me to start this creation. https://busybox.net/live_bbox/live_bbox.html
Welcome to the forums @johnchaney28031.

I don't think you can build it like you want. I also don't recognize that second model either.

What I would do is only do a full reset to factory defaults and then only change/touch the options you need to be enabled. Keep in mind that toggling some options on/off isn't the same as leaving them off in the first place (and some options change the router's behavior if you just land on their page).

You can also search here for the RMerlin script to build your own firmware too, but as far as I remember, you need a Linux build (not Mac) as a base to do that.

Use the Better Search link to find those discussions and other relevant information you may need.
To further state what merlin said, many components dependent on others, even if somehow you could manage it. It will break everything dependent on it. Best thing would be just built you on router, there are literally many open source based software.
