Hi,
Okay. In Gluon both the batman-adv multicast optimizations and bridge multicast snooping are deactivated by default. So I think it's probably an issue with the bridge on your gateway. Does deactivating the batman-adv and bridge multicast stuff make a difference?
Unfortunately not.
Which kernel version and Linux distribution are you using on the gateway?
3.16.0-4-amd64 / Debian Jessie. In the old setup (with 2013.4) it was 3.2.0-4-amd64 / wheezy
Measured on bat0 or on the bridge on top?
On the bridge.
PS: Please keep the mailinglists.
Sorry, I thought it was sent off the list.
