I am running the below scripts for "Transparent Proxy to a Remote Squid 
Box": -

$IPTABLES -t nat -A PREROUTING -i $cusif -s ! $squid_box -p tcp --dport 
80 -j DNAT --to $squid_box:3128
$IPTABLES -t nat -A POSTROUTING -o $cusif -s $cus_net -d $squid_box -j 
SNAT --to $cus_ip
$IPTABLES -A FORWARD -s $eastin_i001 -d $squid_box -i $cusif -o $cusif 
-p tcp --dport 3128 -j ACCEPT

If the daemon dies, I need to remove the above three lines.  How can I 
monitor the Squid daemon from the firewall? 

Regards,
ro0ot
