RE: Configuring a firewall under Unix

[kevin hunter <kevin_hunter () compusa com>]

I execute my IPFWADM script for my Linux Slackware 4.0 machine on
startup from ./etc/rc.d/rc.local as well as on the tail end of my dialup
script.

In addition to the sample IPFWADM script I tossed the following in to
catch my ISP's dynamically assigned IP number... I use $IP_ADD for
personal
preferences instead of $EXTIP





IP_ADD=$(ifconfig | grep -A 1 eth0 | grep inet.\*P-t-P|    \
       sed s/inet.*r:// | sed s/P-t-P.\*// ) 
 echo $IP_ADD > /etc/ip.add
