You're trying to fix a NIC driver-related issue by messing with your firewall, you're most likely looking in the wrong place. May have more luck posting to freebsd-net. One thing to try is disabling hardware checksum offloading (rxcsum, txcsum) to see if that makes any difference, with some NICs it causes issues. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-pf To unsubscribe, send any mail to "[email protected]"
