Using Firewall Linux has a tool called iptables, which is essentially a firewall. It has a nice front end program called ufw. In this task, the objective is to use ufw to set up some firewall policies, and observe the behaviors of your system after the policies become effective. You need to set up at least two VMs, one called Machine A, and other called Machine B. You run the firewall on your Machine A. Basically, we use ufw as a personal firewall. Optionally, if you have more VMs, you can set up a firewall at your router, so it can protect a network, instead of just one single computer. After you set up the two VMs, you should perform the following tasks: ⢠Prevent A from doing telnet to Machine B.
⢠Prevent B from doing telnet to Machine A.
