Re: [B.A.T.M.A.N.] Batman an more than one Gateway

Hi,

I have take a look to the configuration of our gateways. Inho there are some points which are not OK, Broadcasts are rebroadecasted on a wired connection,

please note that batman's payload reboradcast behavior is unrelated to the batman gateway feature. The effect of the batman gateway feature is explained here: https://www.open-mesh.org/projects/batman-adv/wiki/Gateways

Rebroadcast on an interface depends on the interface type. Generally, batman runs on 3 different types of interfaces:

* WiFi: payload broadcasts are transmitted 3 times to increase the chances of a successful transmission * VPN / wired Ethernet: payload broadcast is transmitted once as most sane VPNs don't experience packet loss

Guessing from your interface names you are running VPNs and not wired Ethernet, is that correct ?

this seem for me to be an issue.

What exactly is the issue ?

It is recommended to run the same batman version on all nodes to avoid unexpected behavior. These 2 versions are separated by 2 years of development.
