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 writing a new email thread.
We have been building openwrt 15.05 + batman-adv mesh network for over 2 years, they work great.
hopefully, the batman-adv version you are using is newer than 15.05 ...
- My first thought is to use batman-adv gateway (with 4G modem
connected) as dhcp server, and forward batman-adv interface to wan interface (modem).
1.1) But, there is an issue with this setup. Once a modem is down, nodes that are connected to this batman-adv gateway (with modem) can not automatically "roam" to another batman-adv gateway (with good modem connection).
Why not ? What should prevent nodes or clients to choose another
batman-adv
gateway ?
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. Xuebing Wang
