Actually, I am using a bridge. It is currently between two NICs. We removed the 'upstream' NIC from the bridge and then enabled NetworkManager interface sharing on the bridge. NetworkManager selects the Wi-Fi connection and creates all the plumbing and it works. There are some issues. The first on that list is that we'd like to convince the dnsmasq started by NetworkManager to proxy or forward DHCP request to the Wi-Fi connection.

No, connection sharing starts its own DHCP server on the "downstream" interface (the one with ipv4.method=shared). If you need only to pass frames between two interfaces, probably you can use a bridge instead... > I'm sharing an interface and the Wi-Fi connects to either a > home/small-office router which serves DHCP, or it connects to an access > point which passed DHCP requests to a corporate server. .... however, note that a Wi-Fi client interface usually doesn't work when it is under a bridge. So I think your only option (if I understood well what you want to do), is connection sharing, which creates a different subnet with DHCP on the downstream interface and enables NAT. Beniamino
