Hi all I've got into some strange behavior with ipv6. Somehow ipfw reassembly totally brakes it's operation. As soon as I add a rule "ipfw add 100 reass all from any to any in" all ipv6 operation is not available any more, I can only ping6 localhost. Outgoing ipv6 packets are OK, I can see them via tcpdump on an interface stf0 and after that leaving encapsulated in ip4 through another interface. But all incoming ipv6 packets are blackholed. I can see them arriving as an encapsulated payload in ip4 and after that they disappear. I don't know if this a bug or a feature, using "ipfw add reass ip4 from any to any in" works as a workaround. Shouldn't reass just pass ipv6 packets intact? Or if it is a feature than maybe there should be a note in IPFW(8) man page to not to use reass for anything except ip4?
Yes, reass implemented only for ipv4 and breaks ipv6 packets. It should be fixed, not documented. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
