Well, I see router advertisements (and pings to ff02::1) from the router on both of the two laptops I have handy, and then after a while the openbsd system seems to stop broadcasting -- I no longer see the broadcast ipv6 packets on either laptop, but if I just do "ifconfig ral0 down; ifconfig ral0 up" on the openbsd system then everything seems to come back. So it seems unlikely that the problem is anywhere except on the openbsd system sending. It's interesting to note that the only broadcasts that the openbsd router is going to send that matter in my setup are ipv6 router advertisements -- before I started using ipv4, all the broadcasts would have been arps from the laptops to the router, so I would have never noticed that the router stopped being able to broadcast. - R. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
