Your work was so well received by Harry for the Game Stop that he asks you to create a small network from scratch as a demo of how to configure the entire network of machines. You have four machines and a hub you are connecting to each other and then the Internet as shown below. Complete the network configuration of IP addresses, default gateways, subnet, and network addresses and submit to your instructor.This Chain applies for all packets that are addressed to the firewall INPUT OUTPUT FORWARD This chain applies for all packets originating from firewall and going out of the server O INPUT ⒸOUTPUT FORWARD This chain applies for all packets passing through the firewall from other hosts on the network. The host with iptables is neither the source nor destination of the packet: mainly used to route packets through the machines on the network. INPUT OUTPUT Ⓒ FORWARD This jump target does not respond to a packet at all and does nothing with the packet. It an attack sends a packet. they would not get any response. ODROP ⒸREJECT This jump target responds with an ICMP Destination Unreachable back to the source. This indicates that a server exists, which is beneficial for troubleshooting and for attackers.
