smi...@nimnet.asn.au changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |smi...@nimnet.asn.au --- Comment #1 from smi...@nimnet.asn.au --- >From ipfw(8), second last paragraph: " Due to the architecture of libalias(3), ipfw nat is not compatible with the TCP segmentation offloading (TSO). Thus, to reliably nat your net- work traffic, please disable TSO on your NICs using ifconfig(8)." I don't know about RXCSUM & TXCSUM in this context, but NAT is only for IPv4 - make sure your NAT rules only apply to ipv4 packets specifically - and you certainly need to turn TSO4 off when using either kernel NAT or natd(8), both of which use libalias(3). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-ipfw@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
