Hello!
I had a spare Raspberry PI 4B 4GB laying around so I decided to turn it into a travel router with OpenVpn.
To do that, I followed a Network Chuck tutorial which included these steps:
- Install OpenWRT.
- Purchase USB antenna and USB to Ethernet adapter and then downloaded their relative packages - both devices have been correctly identified (as radio1 and eth1, namely).
- Connected another computer to the Ethernet port of the RPI (eth0).
- SSHed in and changed IP address from the default one, adjusted wireless network on radio0, then disconnected the other computer from eth0 and connected through the wireless network on radio0.
The router now works fine as wireless travel router, using the default radio (radio0) of the RPI as WAN and the additional usb-to-wifi port (radio1) as LAN.
It appears, however, that setting eth1 as WAN is not allowing me to connect to a wired connection (ex. ethernet port in a hotel room or even a port on my switch at home that I know is serving up internet).
Whenever I attempt to connect to a wired connection by plugging a cable into eth1, I get an error message stating that it couldn't get an IP address and the connection shows as not connected to the internet. I have checked that these are working ports I am attempting to connect to.
I would like to be able to choose between having a wired or wireless connection (e.g. WAN on either eth1 or radio0), serving up that connection to radio1 (LAN), but I haven't figured out how to make that happen.
I should also note that I have the Travlemate package installed but disabled at the moment.
Here are my configuration details:

FYI the Raspberry PI is currently connected to my home network wirelessly and serving up internet through radio1 just fine. The moment I plug in an eth cord into my usb-to-ethernet adapter it all goes sideways.
Any help you can provide in much appreciated! Thank you in advance
