Connecting Flexy To Internet Through Ethernet

My Ewon’s LAN IP is 192.168.1.51
I know the internet access is good at 192.168.1.52 because I have other devices connected and getting access.

I’m getting this error.

But here’s my setup. I even tried 192.168.1.66 for the WAN port (This setting does set the local IP for the WAN port, correct? Because it is connected to the same switch as the LAN port.)

You have an IP conflict because the LAN and WAN are on the same subnet. The Ewon is a router and there is no transparent mode, so the LAN and WAN need to be on separate networks.

Thanks. That did it.
