→Set-up Firewall Policies
In addition to the basic firewall established in assignment 1, ensure the following restrictions are met:
#All virtual machines will use iptables as their firewall.#Outgoing traffic is allowed.
#Each virtual machine must be able to check for and install updates using yum.
#Traffic on the loopback interface for each virtual machine is allowed.
#The host machine (and only the host machine) must be able to ssh to them. #ICMP traffic is allowed if it originated within the local network only. #Allow an exception to allow mail messages to be relayed from your '''pine STMP server''' to your '''fir IMAP server'''.#Other than that, only the traffic necessary to support their roles described below above should be allowed.
