# Please make sure you have ipfw_load="YES" and ipdivert_load="YES"
|
|
# in /etc/loader.conf or kldload'ing the appropriate kernel modules.
|
|
# Additionally, you need to have an ipfw rule for the engine to see
|
|
# the packets from ipfw. For Example:
|
|
#
|
|
# ipfw add 100 divert 8000 ip from any to any
|
|
#
|
|
# The 8000 above should be the same number you passed on the command
|
|
# line, i.e. -d 8000
|
|
#
|
|
ipfw:
|
|
|
|
# Reinject packets at the specified ipfw rule number. This config
|
|
# option is the ipfw rule number AT WHICH rule processing continues
|
|
# in the ipfw processing system after the engine has finished
|
|
# inspecting the packet for acceptance. If no rule number is specified,
|
|
# accepted packets are reinjected at the divert rule which they entered
|
|
# and IPFW rule processing continues. No check is done to verify
|
|
# this will rule makes sense so care must be taken to avoid loops in ipfw.
|
|
#
|
|
## The following example tells the engine to reinject packets
|
|
# back into the ipfw firewall AT rule number 5500:
|
|
#
|
|
# ipfw-reinjection-rule-number: 5500
|
|
|
|
# Set the default rule path here to search for the files.
