Hi.
Can anyone make clear for me one thing. In file /etc/rc.firewall
we have two sections which stops RFC1918 and draft-manning-dsua-03.txt
networks:
# Stop RFC1918 nets on the outside interface
[ ... ]
# Network Address Translation. This rule is placed here deliberately
[ ... ]
case ${natd_enable} in
[Yy][Ee][Ss])
if [ -n "${natd_interface}" ]; then
${fwcmd} add divert natd all from any to any via ${natd_interface}
fi
;;
esac
# Stop RFC1918 nets on the outside interface
[ ... ]
If we don't using NAT then we have _two_ sections of _same_ rules,
where the second sections is unnecessary. May be better code is:
# Stop RFC1918 nets on the outside interface
[ ... ]
# Network Address Translation. This rule is placed here deliberately
[ ... ]
case ${natd_enable} in
[Yy][Ee][Ss])
if [ -n "${natd_interface}" ]; then
${fwcmd} add divert natd all from any to any via ${natd_interface}
# Stop RFC1918 nets on the outside interface
[ ... ]
fi
;;
esac
Where the second section which stops RFC1918 and draft-manning-dsua-03.txt
networks is applied only if we really using NAT ?
