May be my changes it no so correct?? Where is a problem? /////////////////////////////////////////////////////// # Stop spoofing ${fwcmd} add deny all from ${inet}:${imask} to any in via ${oif} ${fwcmd} add deny all from ${onet}:${omask} to any in via ${iif} # Stop RFC1918 nets on the outside interface ${fwcmd} add pass tcp from 123.123.123.123 to any ${fwcmd} add pass tcp from any to 123.123.123.123 ${fwcmd} add deny all from 10.0.0.0/8 to any via ${oif} ${fwcmd} add deny all from any to 10.0.0.0/8 via ${oif} ${fwcmd} add deny all from 172.16.0.0/12 to any via ${oif} ${fwcmd} add deny all from any to 172.16.0.0/12 via ${oif} ${fwcmd} add deny all from 192.168.0.0/16 to any via ${oif} ${fwcmd} add deny all from any to 192.168.0.0/16 via ${oif} # Stop draft-manning-dsua-01.txt nets on the outside interface ${fwcmd} add deny all from 0.0.0.0/8 to any via ${oif} ${fwcmd} add deny all from any to 0.0.0.0/8 via ${oif} ${fwcmd} add deny all from 169.254.0.0/16 to any via ${oif} ${fwcmd} add deny all from any to 169.254.0.0/16 via ${oif} ${fwcmd} add deny all from 192.0.2.0/24 to any via ${oif} ${fwcmd} add deny all from any to 192.0.2.0/24 via ${oif} ${fwcmd} add deny all from 224.0.0.0/4 to any via ${oif} ${fwcmd} add deny all from any to 224.0.0.0/4 via ${oif} ${fwcmd} add deny all from 240.0.0.0/4 to any via ${oif} ${fwcmd} add deny all from any to 240.0.0.0/4 via ${oif} #Allow anything to internal network ${fwcmd} add pass all from ${inet}:${imask} to ${inet}:${imask} via ${iif} # Allow TCP through if setup succeeded ${fwcmd} add pass tcp from any to any established #Allow ICMP ${fwcmd} add pass icmp from any to any icmptypes 8,0,11,3 # Allow IP fragments to pass through ${fwcmd} add pass all from any to any frag # Allow setup of incoming email ${fwcmd} add pass tcp from any to ${oip} 25 setup # For FTP ${fwcmd} add pass tcp from any to ${oip} 21 setup # Reject&Log all setup of incoming connections from the outside ${fwcmd} add deny log tcp from any to any in via ${oif} setup # Allow setup of any other TCP connection ${fwcmd} add pass tcp from any to any setup # Allow DNS queries out in the world ${fwcmd} add pass udp from any 53 to ${oip} ${fwcmd} add pass udp from ${oip} to any 53 # Allow NTP queries out in the world ${fwcmd} add pass udp from any 123 to ${oip} ${fwcmd} add pass udp from ${oip} to any 123 ////////////////////////////////////////////////////// __________________________________________________ Do You Yahoo!?
