Week 1 SYS‐255 - Foren-Ken/tech-journal GitHub Wiki

This week focused on setting up the initial environment for SYS-255. This included setting up the pfSense firewall between my LAN and the simulated WAN connecting other student's LANs.

What is pfSense?

pfSense is a firewall which filters traffic between two networks. Currently in my environment, this is the gateway between my network and the internet. I can only imagine how this will be used in future classes to resitrict traffic or to allow certain traffic.

How to setup pfSense?

Two things must be setup before traffic between the two networks, connected via the pfSense machine, can communicate.

1. This would be setting the interfaces properly to signify what is the "LAN" interface and what is the "WAN" interface. This is done using the "1" option.
2. The IP Addresses the pfSense machine will use on either network. This is done by using the "2" option in pfSense.

When pfSense is set up to work on both interfaces, the firewall can be interacted with via the web-browser for a nice GUI. This is done by inputing the IP address of the firewall and using the credentials User:"admin" Pass:"pfsense"
