Hello
I got everything working on CentOS 5.3. However iptables rules will not get saved unless you do # /etc/init.d/iptables save

This will make your settings survive a reboot.

* DNS is not working even when specifying it in /etc/resolv.conf

I had to install bind on the router in cash-only mode.

Guz Job well done on this tutorial.Am wondering whether when you are MASQUERADING AND FORWARDING you need to retain the comments on your script as shown that is

——————————————-
# iptables –table nat –append POSTROUTING –out-interface eth0 -j MASQUERADE
# iptables –append FORWARD –in-interface eth1 -j ACCEPT
———————————————-

The comment symbol #

I would be more than happy to pay you to make my headache go away!!!

I’m so frustrated with routing and switching I could scream. I can’t ping any LAN computer from the router box.

1. Those having problems like “…can ping the IP address but can’t ping the site…” you can use the DNS server 4.2.2.2 in /etc/resolv.conf(open as root)
2. those who can’t even ping the IP address ensure you have the right gateway specified in your network setttings.
