is compatible with 4.4.19 in that if a relative path name is
supplied, then '/usr/' is prepended to the name.
2) A new ACCOUNTING_TABLE option has been added to shorewall.conf and
shorwall6.conf. The setting determines the Netfilter table (filter
or mangle) where accounting rules are created.
When ACCOUNTING_TABLE=mangle, the allowable sections in the
accounting file are as follows:
PREROUTING
INPUT
OUTPUT
FORWARD
POSTROUTING
Present sections must appear in that order.
