Hi Marek,
Thank you for your help, as I did not subscribe to the mailing list, I
did not get your reply. I subscribe to the mailing list now and I am

When modem (for WAN uplink) at gateway is down and loses internet
connection (but batman-adv connections with clients are good and dhcp
server works good), can batman-adv clients know that internet connection
at gateway is lost and "roam" to another gateway with good internet
connection?
Thanks.
