At least on Solaris, you need to disable checksum offloading to pass packets through an IPfilter firewall (check the IPFilter FAQ). I gather that the outgoing packets are marked as "checksum valid" so the NIC doesn't re-compute the checksum and it winds up wrong. If you disable IPfilter and just use the box as a straight router, does it then work when you enable checksum offloading? If so, then I think you've bumped into the same (mis-)feature. -- Peter Jeremy _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
