IPTABLES med LOOPBACK på lo

jeg har et iptables script som ikke tillader at jeg laver loopback på lo altså 127.0.0.1, hvordan løser jeg det, mit script ser sådan ud:

#!/bin/sh

# Diable forwarding
echo 0 > /proc/sys/net/ipv4/ip_forward


LAN_IP_NET='10.0.0.1/8'
LAN_NIC='eth1'
WAN_IP='217.*.*.*'
WAN_NIC='eth0'

# load some modules (if needed)
modprobe ip_nat_ftp
modprobe ip_conntrack_ftp

# Flush
iptables -t nat -F POSTROUTING
iptables -t nat -F PREROUTING
iptables -t nat -F OUTPUT
iptables -F

iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT

# enable Masquerade and forwarding

iptables -t nat -A POSTROUTING -s $LAN_IP_NET -j MASQUERADE
iptables -A FORWARD -j ACCEPT -i $LAN_NIC -s $LAN_IP_NET
iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT

# Open ports on router for server/services
iptables -A INPUT -j ACCEPT -p tcp --dport 21
iptables -A INPUT -j ACCEPT -p tcp --dport 22



# STATE RELATED for router
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

# Open Ports to server on LAN


# Enable forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
