Hi, When I use FreeBSD-6.0 Release (also FreeBSD-5.4), I found IPSEC can't coexists with MAC. When the IpSec is setup, and we connects the TCP server with IPSEC and MAC support, the server innevitably crack. Because the m_pkthdr of some mbuf is mangled by unknown reasons. Following is my kernel configuration: options MAC options MAC_DEBUG options UFS_EXTATTR options

Another checksum offload problem was reported on xen-users, when using a domU as a firewall: http://lists.xensource.com/archives/html/xen-users/2006-04/msg01150.html It also fails without VLANs. The path from dom0->domU with ip_summed==CHECKSUM_HW/proto_csum_blank==1 is broken. - skb_checksum_setup() assumes that a checksum will definitely be calculated in dev_queue_xmit(), but the
