Week 2 (January 19) - Protecting your Local Network with a Packet Filtering Firewall

Lab 2 Modify the sample firewall script and run it on your LAN gateway and hosts to allow access to the following services on your LAN

• ssh, and
• all the ports specified in the file /etc/openports
  • the first field of each line is the port number, the rest is description or comment
  • line starts with the # sign is a comment
• all the ports to be forwarded specified in the file /etc/fwports
  • this file should exist only on a gateway/router machine
  • line starts with the # sign is a comment
  • the first field of each line is the port to be forward, the rest is description or comment

After testing your firewall, use the iptables-save command to save the output to a file. Name the file on the gateway as "gw-fw.txt" and name the file on the host as "host-fw.txt".
