I have an LTE card on wwan0 configured with ip address and default gateway with system system set to use it. All this is done outside of VyOS configuration. How can I now get VyOS to see and managed and more importantly firewall that interface? Is there a way to create a bridge with a dummy device VyOS can see and bridge wwan0 to it? I tried it but it didn't work (or I didn't do it correctly).
My goal was to configure this in VyOS but using wirelessmodem (which I did get to work) but it is subject to using ppp which has a hard bandwidth limit I believe. I am now using mbim to make the connection to the carrier.
