Also dose "/etc/init.d/iptables save" reflect the proc->ip_forward setting? Change /etc/network/options, that is where I set this.
What do you mean by this?
# cat /etc/network/options ip_forward=no spoofprotect=yes syncookies=no
My new script:
# cat myiptables #!/bin/sh
# Disable forwarding echo 0 > /proc/sys/net/ipv4/ip_forward
# load some modules (if needed) #modprobe ip_nat_ftp modprobe ip_conntrack_ftp
# Default rules iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT
# Flush iptables -t nat -F POSTROUTING iptables -t nat -F PREROUTING iptables -t nat -F OUTPUT iptables -F
# Localhost iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT
# Open ports on router for server/services iptables -A INPUT -s 1.2.3.4 -j ACCEPT -p tcp --dport 20 iptables -A INPUT -s 1.2.3.4 -j ACCEPT -p tcp --dport 21 iptables -A INPUT -j ACCEPT -p tcp --dport 22 iptables -A INPUT -j ACCEPT -p tcp --dport 25 iptables -A INPUT -j ACCEPT -p tcp --dport 80 iptables -A INPUT -j ACCEPT -p tcp --dport 143 #iptables -A INPUT -j ACCEPT -p tcp --dport 443 iptables -A INPUT -j ACCEPT -p tcp --dport 993

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