Is it possible to have the RUT240 give its 4G Wan IP to any PC without specifying a MAC address?
From memory, setting the 4G interface to bridge mode requires the target mac (will not let saving without).
I'm trying to see if it's possible to avoid a reconfiguration of the RUT240's bridging target MAC for cases where the router behind died and has to be urgently swapped.
Ideally, the RUT240 would give the 4G IP to the latest client on its LAN port - is that possible?
