Wh at do you mean by setting up the bridge twice? Is it about the bridge_* directives? I thought configuration of IPv4 and IPv6 interfaces were independent, thus allowing (and needing) separate configuration.
If you shall not repeat those, that might be the reason why I crashed the network interface altogether... I also cannot help but notice you use the accept_ra directive. Is not that intended for routers? Thanks, --- *B.
