So I've tried to get this for 3 weeks and have only half way succeeded in making an isolated network on eth0 that will talk to the wlan0 network, but that's not what I'm after.
Make a quick diagram to make sure we all understand my goal.
Basically the PI is connected to the router with wlan0 and will serve internet and network abilities (bi-directional) to the ethernet port (eth0).
I have software that will run on devices and need to be discovered on the network so I can get access to them from inside the LAN.
So far using parprouted I was able to get it to work, but ONLY using static IP's on the Device 1 and Device 2 (eth0 cnnected devices). While this works for this one case use, I'd like it to be more universal and just another tool in the bag I can carry with me to help solve problems.
My understanding is that part of the problem is that the built in wifi doesn't do 4addr mode. I'm willing to use a seperate USB wifi dongle (and I did try but it didn't work), but I also saw someone on Superuser ( https://superuser.com/questions/1601099 ... o-specific ) mentioned creating a virtual wlan interface and using some bridges built with udev.
I will admit, I have a hard time understanding some of the steps. I was able to make all of the udev devices as instructed, but I didn't understand where to go from there.
I'm using NetworkManager as the latest 32bit (I need 32bit for some software that also needs to run on the pi to connect to a device) image came out of the box for my Pi 3b+. I'd be willing to change over to wpa_supplicant but EVERY time I try to convert it from NM to WPA_Supplicant I break the networking so bad that I just end up re-imaging to get back and start over (done that half a dozen times at least... I now have 3 cards I rotate through so I can clone one while breaking the next one. LOL ).
Does this seem like it could be done with the virtual interface work around?
If so, what are the steps I'm missing to making this work?
