How to make OpenWRT work properly in GNS3
No matter what I try in GNS3 to get OpenWRT to run properly, I cannot get it to properly work with other GNS components. I can connect two devices through a switch and ping back and forth, but not to the OpenWRT device, not matter what.
When I ping OWRT an ARP request can be seen, but no reply is sent. When I ping from OWRT to a device, a requests and replies can be seen, but OWRT does not register the correct Mac-Address. It is filled with all 0s instead of the actual address that was replied.
I've tried an OWRT Docker container running on the GNS3 VMWare server, VMWare VM running a GNS3-controlled instance and a VirtualBox GNS3-controlled instance. All show exactly the same behaviour and I cannot seem to find any tutorials on how to make it work... none that actually work anyway.
Running on MacOS Mojave.

OpenWRT is meant for wireless routers and therefore has bridge interfaces setup--though not 100% if this is true of x86 build if you are using that. Weird things can happen here. Try disabling all bridges (use shell) and ensure you are using the physicaleth0interfaces.

I would love to see if someone answers this. I have experienced this and other bizarre bugs in GNS3 with OpenWrt. What version image are you using?

@LawrenceC Your comment did the trick. If you will post it as an answer, I will credit you with answering the question. What can be done is 1 - to add additional ports and use those and leave eth0 alone. Or 2 - comment out anything for eth0 / lan where it says type 'bridge' and proto 'static' (don't know if the proto needed to be commented out, but it worked for me) and reboot

Actually, I wasn't able to connect anything to the internet via eth0 or eth1. If you just stick with adding new ports and working with those, so far all is ok. Although I haven't tested that much yet
