Changes

You will now get additional practice on troubleshooting iptables by downloading a running a shell script that will create iptables rules that will cause problems. You will then need to use tools and procedures (IPTABLES Troubleshooting Checklist) to determine the cause of the problem and fix that problem.

#Download and run the following script: http://scs.senecacollege.ca/~andrew.smith/ops335/lab_practice_iptables.sh<br><br>This will display a menu of exercises. You can choose any of the items in order, but you should attempt all of them. The script will first reset the firewall settings to CentOS defaults and then make some modifications from those defaults.<br><br>
