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".
