Lab 01 ‐ Environment Setup - AidanP017/Aidan-SYS-255 GitHub Wiki
Overview
In this lab, we utilized the vSphere application through the Champlain network to configure routing services between a pfSense firewall (fw01) and a virtual workstation (wks01) using cyber.local credentials.
Notes:
-
By right-clicking on the firewall in vSphere and clicking on Edit Settings, you can select a network adapter as well as add an additional network adapter to establish connections for, which was used in the case of this lab to cable the firewalls using two network adapters.
-
In addition, by selecting a network adapter in the settings, you will be able to view its MAC address which is needed to verify network connectivity between vSphere and pfSense.
-
By typing "1" in the "Enter an option" field within the fw01 terminal, you can assign interfaces to specific network devices such as wide area networks (WANs) and local area networks (LANs).
-
By typing "2" in the "Enter an option" field within the fw01 terminal, you can assign IP addresses to existing interfaces through either IPv4 or IPv6 connectivity.
-
By typing "8" in the "Enter an option" field within the fw01 terminal, you can utilize a shell that allows you to enter specific commands---such as pinging champlain.edu as demonstrated in this lab.
-
By right-clicking on "This PC" in File Explorer and clicking on "Properties", you can access settings for the PC as well as rename it to whatever desired, such as "wks01-yourfirstname" as done in this lab.
-
By navigating to the Ethernet settings, clicking on "Change adapter options", double-clicking on the network connection, clicking on "Properties", and double-clicking on "Internet Protocol Version 4 (TCP/IPv4)", you can assign IP addresses as well as a DNS server for this type of network connection if capable.
Terms:
pfSense - According to zenarmor.com, pfSense is an operational system that acts as a free open source firewall and router for physical computers and virtual machines. pfSense also provides a plethora of features that allow for further expandability as well as less potential security vulnerabilities to arise. Today, pfSense is used all across the globe for trustworthy and heavy-duty firewall security in cloud systems.
RFC 1918 Network - According to techtarget.com, RFC 1918 refers to "Address Allocation for Private Internets", which identifies the methods in which private IP addresses are assigned on TCP/IP networks. In addition, RFC 1918 expands the usable number of IP addresses that are available for IPv4 connectivity as well as prevents public IP addresses from exhaustion prior to IPv6 connectivity being adopted.
Azure Firewall - According to aviatrix.com, the Azure Firewall is a cloud-based network security service that protects virtual networks. At the same time, the Azure Firewall can create and log policies regarding application and network connectivity as well as enable outside firewalls to identify traffic originating from a virtual network.
