It looks like seqno requests are not getting through.  Are you sure that
you don't have a faulty firewall somewhere that doesn't let through
unicast Babel packets?

A patch to set the src field will be merged soon (see
https://github.com/jech/babeld/pull/18), but you should try to understand
why this is needed in the first place -- again, I suspect a faulty
firewall configuration.
