Coyote Linux , como configurar su firewall

[rex]

Escribi lo que me dijiste en la consola y me dio el error siguiente:
usr/sbin/ipmasqadm: No such file or directory

El Script del firewall dice lo siguiente:

#!/bin/sh
#
# Coyote Firewall Startup Script
# called by: etc/rc.d/rc.inet, /etc/ppp/ip-up, /etc/dhcpc/dhcpc.updown

logger -p daemon.info -t rc.firewall "Firewall script called with: ${@}"


PATH=$PATH:/usr/sbin

# Load Coyote variables
if [ -z "$CONFIG_LOADED" ]; then
. /etc/coyote/coyote.conf
fi

if [ -e /tmp/netsubsys.state ]; then
. /tmp/netsubsys.state
fi

IF_INET=$1

if [ -z "$IF_INET" ]; then
if [ "$INETTYPE" != "PPPOE" ] && [ "$INETTYPE" != "PPP" ]; then
IF_INET=eth1
else
IF_INET=ppp0
fi
fi

IPADDR=`getifaddr $IF_INET`

# Block traffic that is not part of an existing connection or part
# of a permitted ACL list
iptables -D INPUT -i $IF_INET -m state --state NEW -j DROP 1>/dev/null 2>&1
iptables -A INPUT -i $IF_INET -m state --state NEW -j DROP
iptables -D FORWARD -i $IF_INET -m state --state NEW -j DROP 1>/dev/null 2>&1
iptables -A FORWARD -i $IF_INET -m state --state NEW -j DROP

iptables -F remote-admin
# Remote Admin allowed ports
iptables -A remote-admin -i $IF_INET -p tcp --sport 1024: --dport 22 -j ACCEPT

# Activate IP Masquerading - You can comment this line out to use Coyote as
# as a true IP router. The masq script switches the default forwarding
# policy to DENY (to prevent non-masq'ed routing) and establishes masquerading.
. /etc/rc.d/rc.masquerade $IF_INET


Decis que le agregue esas lineas al final ?

Gracias.

PD: No las conozco, pero el apellido me suena bastante.
