B.A.T.M.A.N. has a feature called gateway mode which is useful when there are two or more nodes having internet access. This mode allows other nodes to connect to the internet via the fastest node, while also preventing multiple DHCP replies.

We could use naxalnet.conf to configure it

[gateway]
mode=client
# bandwidth
upstream=20M
downstream=40M

We could use naxalnet.conf to configure it ```ini [gateway] mode=client # bandwidth upstream=20M downstream=40M ```

How about we add mode=auto in naxalnet.conf which will check for internet access without bat0, and if there is internet access, set mode to server, or to client otherwise.

If we implement this, we have to think of some way to find out if any of the ethernet ports is bridged to a DHCP server.

I'm working on this on a branch gateway.

My idea is to use a temporary networkd *.network based on the bridge0 config file and replace Name=bridge0 in [Match] with en* and eth*. Then reload networkd and then check if any of them is routable. If any of them is routable, set gateway mode in batman-adv to server; else set it to client.

Implemented auto gateway mode. This is now the default. This can be configured with
