[B.A.T.M.A.N.] Mesh hickups with 2014.3

Hi,

in the last days we upgraded nearly all (~500) routers of our Freifunk -mesh from 2013.4 to 2014.3. The most things run fine again, but with some routers we have connectivity issues as follows:

- gateway gets alfreddata from router - router pingable via batctl - ping via linklocal, ULA and public-IPv6 from gateway to router not possible - other routers in the same mesh can ping it via ULA etc (connected via the same fastd-VPN)

Public-IPv6 is announced from a gateway via radvd into the mesh.

Unfortunately we are out of ideas where we can search for the reason.

Regards bjo
