The purpose of this lab is about how to properly configure a pfsense firewall for a server, how to implement Network Address Translation (NAT), creating a Common Address Redundancy Protocol (CARP), and creating a Virtual IP and implementing firewall rules. The purpose of a firewall to protect your internal network from any malicious threats that are out there on internet.

There are a multitude of settings on a pfsense firewall, part of this lab was to create the Common Address Redundancy Protocol (CARP) Virtual IP and attach that public address to the Wide Area Network (WAN). In order for these effects to take place you have to manually apply the changes on the top tight side tab. After this step you have to use the Network Address Translation (NAT) feature on the firewall in order to be able to attach that internal IP to the Outside IP.

The second part of this lab was to create a rule that allows traffic to pass from the public network to the private network. You have to create several rules in order to make this work, the internal network is not usually routable but by using NAT you are afforded that ability. The rules  set in place permits certain traffic that you specified to be able to access the public but not vice versa.

Ultimately using any firewall will make any environment more secured. This will also involve making sure you are using the firewall as a security device. Just because you have a firewall doesn't mean you are protected. You have to make sure you do your due diligence and configure the firewall to your specific environment needs.
