I am having problems getting multicast video over my 2 node mesh. I am building under openwrt and the version is 0.3.0-alpha rv1715.
I have a lan bridge on each side. If I directly add ath0 to the lan bridge the video works fine. But since I want to mesh, I put ath0 into bat0 instead, and then I put bat0 into the bridge. This works for all my traffic that put across it so far except the multicast video. A tcpdump comparison of both sides shows that after about 32 packets data starts getting dropped. The video is about 1Mbs.
Given this thousand foot view of the problem, is there something obvious I might be missing? I've set the mtu on ath0 to 1524. Everything else seems to work fine, including copying a file over the mesh setup that is 20MB at a speed of 578.9KB/s and the md5sum was right.
