episode: Configuring a Firewall.
Could you explain exactly how the pfSense firewall-box was connected to Don's laptop? It was mentioned that 3 network cards were being used (i.e., LAN, WAN, DMZ). As I understand this, 3 Network cards were installed in the box that pfSense was installed on. How was this box then connected to Don's laptop? There was some activity where some ?cables? were pulled affecting the LAN, WAN, DMZ connections? Could you explain these hardware connections?
