frankly why don#t you throw away all that crap and start write a
"iptables.sh" which is even for a datacenter firewall doing NAT and
firewalling in front of a /24 network no rocket science

also looking what rules are currently active is a no-brainer

[root at firewall:~]$  cat /usr/local/bin/firewall_status
#!/bin/bash

IPTABLES="/sbin/iptables"
DEFAULT_COLOR_START="\e[36m"
DEFAULT_COLOR_STOP="\e[0m"

function firewall_status
{
 # Ausgabemodus
 if [ "$1" != "short" ]; then
  VERBOSE="--verbose"
 fi
 # Alle geladenen Tabellen sortiert durchlaufen
 for table in `cat /proc/net/ip_tables_names | sort`
 do
  echo -e
"${DEFAULT_COLOR_START}---------------------------------------------------------------------------------------${DEFAULT_COLOR_STOP}"
  echo -e "${DEFAULT_COLOR_START}`echo $table: | tr a-z
A-Z`${DEFAULT_COLOR_STOP}"
  echo -e
"${DEFAULT_COLOR_START}---------------------------------------------------------------------------------------${DEFAULT_COLOR_STOP}"
  $IPTABLES -t "$table" --list --numeric --line-numbers $VERBOSE
  echo ""
 done
}

if [ -t 1 ];
then
 firewall_status "$1" | less -R
else
 firewall_status "$1" | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g"
fi
