Iptables-- internal network
 

i need to come up with a iptables script for my firewall. my firewall has to nic cards. one connects to the external and 1 to the internal. So anybody knows how to create a firewall iptables script which only allows the internal network to be able to connect and ping to the web server in the external network. and the extenal network can not enter to the internal network at all..

thanks..

Also i want to eliminate the single point of failure so i am using heartbeat for failover. the problem is. i don have a clue for to configure it. can anyone be an angel and help me with this 2 problems. i have to solve it next week.

thanks..

iptablesrocks.org has firewalls that should suite your purpose. You can edit them to include more custom and specific rules for your purpose, but generally they work right out of the box for what they say to use them for.

You could also go to http://easyfwgen.morizot.net and use the online tool to generate a custom firewall.
