fBSD nat ipfw
i am running nat on my freeBSD and web/ftp server.
The rule allow ip from any to any must always be? or how? if i accept all packets to go on my ep0 which diverts all to my intranet it doesnt help, must the rule allow ip from any to any always be ?
even if many rules are between divert rule and allow from any to any rule, system still be able easy hacked :)
p.s. sorry for my lang. :)

NAME
audit_add_rule_data - Add new audit rule
SYNOPSIS
#include <libaudit.h>
int audit_add_rule_data (int fd, struct audit_rule_data *rule, int flags, int action);
DESCRIPTION
audit_add_rule adds an audit rule to one of several kernel event filters. The filter is specified by the flags argument. Possible values
for flags are:
o AUDIT_FILTER_USER - Apply rule to userspace generated messages.
o AUDIT_FILTER_TASK - Apply rule at task creation (not syscall).
o AUDIT_FILTER_ENTRY - Apply rule at syscall entry.
o AUDIT_FILTER_WATCH - Apply rule to file system watches.
o AUDIT_FILTER_EXIT - Apply rule at syscall exit.
o AUDIT_FILTER_TYPE - Apply rule at audit_log_start.
The rule's action has two possible values:
o AUDIT_NEVER - Do not build context if rule matches.
o AUDIT_ALWAYS - Generate audit record if rule matches.
RETURN VALUE
The return value is <= 0 on error, otherwise it is the netlink sequence id number. This function can have any error that sendto would
encounter.
