CYSE 270: Linux System for Cybersecurity Lab 13 – Advanced Network configurations Scenario: You, as a network admin, are going to set up your Ubuntu VM as a gateway to provide Internet access to another client Ubuntu VM. The client VM needs to be in the same internal network as the gateway (as shown in Figure 1). Once the connection is ready, you need to configure the firewall to secure the network properly. The following requirements need to be satisfied to receive full credits. Please note that you need to customize the value in the fields marked in RED above. Please configure the network with the following requirement: Task A –Network Configuration (60 points) 1. In the virtual box setting, connect two VMs in the same internal network, “internal_{UIN}”. Replace {UIN} with your real UIN. 2. Change the hostname of the Client VM to “{MIDAS}-Client.” Replace {MIDAS} with your real MIDAS. 3. Configure the temporary IP address on the Gateway Ubuntu, as shown in Figure 1. 4. Configure the temporary IP address, routing table, and DNS server on Client VM as shown in Figure 1. 5. Configure gateway Ubuntu to forward the traffic from the Client to the Internet. 6. Test your ping connection to 8.8.8.8 and www.google.com, respectively. Task B –Firewall Configuration (40 points) 1. Configure the iptables on the gateway Ubuntu to block all the inbound ICMP packets from the Client VM. 2. Configure the iptables on the gateway Ubuntu to block all the outbound ICMP packets that originated from the gateway Ubuntu itself. Extra credit: Set the permanent IP address on the Client Ubuntu based on the above network topology.
