The jail.conf is: vnet; vnet.interface =3D "vnet0"; exec.prestart =3D "ifconfig ${vnet0} name vnet0"; exec.poststop =3D "ifconfig vnet0 name ${vnet0}"; exec.start +=3D "/bin/sh /etc/rc"; exec.stop =3D "/bin/sh /etc/rc.shutdown"; exec.consolelog =3D "/var/log/${name}.log"; host.hostname =3D "${name}"; path =3D "/jail/${name}"; j1 { $vnet0 =3D "cxlv1"; } j2 { $vnet0 =3D "cxlv2"; } There are two hosts direct connected via cxl0. The problem is visible when pinging (1) between jails on the same host and (2) from an affected jail on host 1 to host 2. On an unaffected host both of these operations succeed. Using tcpdump on the physical (cxl) and virtual (cxlv) interfaces shows the= ARP requests and responses, but in an affected jail the ARP tables aren't updat= ed. --=20 You are receiving this mail because: You are the assignee for the bug.=
