Sysctl throws an unknown oid for the line
net.inet.ip.check_interface=1
The variable has been renamed
from
check_interface
to
rfc1122_strong_es
Documented as:
Enable a consistency check between the destination address
* and the arrival interface for a unicast packet (the RFC 1122
* strong ES model) with a list of additional predicates:
* - if IP forwarding is disabled
* - the packet is not locally generated
* - the packet is not subject to 'ipfw fwd'
* - Interface is not running CARP. If the packet got here, we already
* checked it with carp_iamatch() and carp_forus().
Default /etc/sysctl.conf change required:
old
IPv4 security additions
net.inet.ip.check_interface=1
new
IPv4 security additions
net.inet.ip.rfc1122_strong_es=1
Should I raise a ticket?
