trouble with ip tables
here is my setup. i have setup two servers. on one i have set up by the perfect server how-to-ubuntu-8.04 server , ( i will call this one s1.example.com ) the other is ubuntu 8.04 server also but it only has dns (bind9) installed ( i will call this one dns.example.com ). i have one static ip from my isp. the dns setup of both servers makes s1.example.com the master for my domain and dns.example.com the slave. dns.example.com has 2 eth ports, one configured with static ip from my isp and the other for my internal network.
also on the internal network i have 1 client that i use for admin purposes. this client can use all functions on the servers ie. web pages, ftp, mail, etc.... and the client and both servers can reach the internet just fine. i have enabled forwarding, and i have added this to my /etc/rc.local file as instructed per how-to:
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
# In order to enable or disable this script just change the execution
# By default this script does nothing.
sysctl -w net.ipv4.ip_forward=1
/sbin/iptables -P FORWARD ACCEPT
/sbin/iptables --table nat -A POSTROUTING -o eth1 -j MASQUERADE
#/sbin/iptables -A POSTROUTING -j MASQUERADE
this is my first setup. it works perfect on my internal network.
also i did not install ispconfig on this system.
any help with this would be very much appreciated,
