Weekly notes and reflections - abubakeralokozay/SYS-255-01-System-Administration-and-network-services GitHub Wiki

First, we started with setting up vcenters and configuring all the resources needed which I will go into more in deep below to explain each step.

  1. set up the vcenter,
  2. practiced how to take snapshots and revert to where we took the snapshot.
  3. also familiarized with vcenter.

The PfSense firewall will provide routing services between a Local Area Network and Wide Area Network in your VSphere environment.

Power on your fw01 VM and Open a VM Console


Find the menu items or icons that allow you to first power on, and then open a web console to your firewall virtual machine.



Your console should now look similar to the following after power on and login:

💡The default username and password for pfsense is listed in Default Passwords on our Home Page --

Step 2: Set interface IP address The first interface em0 will be assigned to an WAN address that is documented in the course Network Assignments in Canvas. This interface represents the outside of your network. Make sure to use your assigned IP address instead of the instructor IP address shown in the following screenshots. Select 2 to Set interface IP Address Select 1 again to pick the WAN interface Do not use DHCP for the WAN IPv4 address You are using a 24 bit subnet mask For the WAN, your upstream gateway is 10.0.17.2 Use the gateway as your IPv4 name server as well We will not be using IPv6, respond no when asked about DHCP. Press to bypass IPv6 configuration When asked about HTTP for the GUI, respond no (we want to use secure https) Select 2 again to configure the other Interface's IP Address Select 2 to pick the LAN interface We are not using DHCP Your LAN IP Address is 10.0.5.2. This is the same for every student. You are using a 24 bit subnet mask You do not have an upstream LAN gateway (you are the gateway for the LAN). Press No DHCP Press to bypass IPv6 configuration Do not enable a LAN DHCP Server Do not revert to HTTP

I have configured the wan and LAN by assigning IP addresses. After that run the workstation and create an admin user. you can create an admin user by going to 'lusrmgr.com'

Open File Explorer
Right-click on “This PC”
Click “Properties”
Click on “Change Settings”
Click “Change” next to “To rename this computer…”
Then type: wks01-yourfirstname
Check “firstname” to your real first name.
 you should be able to access the admin user.

Then connect the VM to the internet by setting up the Internet Protocol Version 4- properties

  • Control Panel
  • Network and sharing
  • Ethernet0
  • Properties

Ip Address 10.0.5.100 subnet mask 255.255.255.0 Default Gateway 10.0.5.2 preferred DNS server 10.0.5.2

fw01 gui configuration You may have noticed that your Windows 10 system is not connected to the internet, so we will need to adjust our firewall (fw01) to make this happen. Navigate to fw01's IP LAN IP address (bypass any certificate warning).

The following are screens where you need to change the default. Skip over the wizard and leave the setting checked to override the DNS server on PPP/WAN System Wizard: General Information Hostname: fw1-yourfirstname Domain: yourfirstname.local Primary DNS: 8.8.8.8 Secondary DNS: 1.1.1.1 System Wizard: Configure WAN Interface RFC1918 Networks: Uncheck "Block private networks from entering via WAN" System / User Manager: Set Root Password Up to you. If you set it, then you need to remember it!
