I've installed Security Onion in a VM and am trying to mirror all traffic that goes across br-lan to my Security Onion install. I've found many tutorials on how to do this but they all seem to have been made for older versions of OpenWrt and I can't get any of them to work. I'm running OpenWrt 23.05-rc3 on a Reyee AX3200 E5. Can anyone point me in the right direction on the current way to do port mirroring?
Thanks for pointing me to that post, I had seen it but I missed the list of packages needed. Once I got the needed packages installed I was able to run the script to set up mirroring. It looks like it's working, looking at my traffic graphs lan1 looks to be a mirror of br-lan which is what I wanted. I'll follow up once I have SO working and can confirm this is working end to end. Thanks for your help.
