Possible to configurate fallback dhcp server?

Hello!,

So I'm trying to build a custom image for the Devolo Magic 2 Next, and currently exploring configuration possibilities.

as how I have configurated it now with uci-defaults is that it behaves as a dumbap so the wan interface gets the same ips as for the clients connecting to over wifi.

lan1 is for joining lan as maintenance network and lan2 can be used as wired wan.

now my issue is this:

I want wireless to fallback to a wan alias with its own dhcp server in case the normal wan doesn't get dhcp, I know that some OEM firmware based powerlines can do that and I think this is needed because walking to my pc or having a long wire is annoying for recovery.

is this archievable with an alias?, I attempted this but maybe wifi need a restart but it seem to not work, or should I look into something like mwan3 ?

I have had some tries with watchcat but unfortunately watchcat only events on down, but not when internet is restored I could in theory script a while loop but I think it can be easier.

would be interesting to know if someone tried a configuration with fallback functionality over wifi.

many thanks :smiley:

There can only be one dhcpd in your network, unless you go full enterprise HA (kea and friends, it's possible, but you don't want that).
