VDI-LAB-2018 - Part 2 - Pfsense vRouter configuration

Summary:

In this part, we are going to download and install pfSense vRouter. We are going to create the first VM of the environment, then install and configure pfSense router. Also, we will add openVPN to the router, configure the server and the client. Skip this section if you don’t need a router or already have one.

This is part 2 out of 12 of the VDI LAB series. Check out the introduction first.

The ultimate VDI deployment guide (from scratch) with VMware vSphere 6.5 and Horizon View 7.3 - 2018. 😉

1. Prerequisites

  1. Download pfSense open source firewall and router: https://www.pfsense.org/download/
Download pfsense
  1. Copy the ISO to an accessible datastore.

NOTE: Create a folder to store all software ISOs to be used during the whole VDI deployment

  1. After reboot pfSense welcome page will be displayed. From this page, let’s set the LAN interface, that will be used for Web Configuration later.

  • Hit number 2 to access Set interface(s) IP address option.
  • Select option 2 for LAN and follow the steps,
  • Input IP address for the router and mask. Mine will be 10.0.0.1/20.
  • I won’t use DHCP into the router, I will configure the DHCP services into the Active Directory server.

4. PfSense Configuration

  1. Access your router via web from the LAN IP address, 10.0.0.1. Pfsense default User/Password is: admin/pfSense
pfsense
  1. First, go to Interfaces / WAN and disable the last two options, Block private networks and loopback address and Block bogon networks.

Don’t make any other change and don’t click in Apply changes yet.

  1. Go to Firewall / Rules. Let's add two rules, first click on the Add button.
Image 14 1
  1. For the first rule, change only Source and Destination sections as the image below and leave the rest as default, click Save.

  1. Reboot the system from Diagnostics / Reboot and click Reboot. Wait for the system and access to the web GUI again.
  2. Now, Let’s configure the Interfaces, Go back to Interfaces / WAN. Make sure that the interface is enabled, I am going to use DHCP for my WAN interface and disable IPv6 Configuration Type, the rest is left by default. If static IP is needed, change IPv4 Configuration Type to Static and add the IPv4 Address and Upstream gateway. Click Save.

LAN interface was previously configured from the CLI, so I won’t change it but can be modified if needed, just like the WAN.

5. PfSense OpenVPN

This section can be skipped. For the sake of easily accessing the whole VDI-LAB remotely, openVPN will be installed into this router. I consider this important to manage and monitor all the components form my Client PC.

First, we need to create certificates that will be needed for the connection, then install openVPN Server into the virtual router and the openVPN client in the Client PC.

NOTE: Port 1194 must be open in the router providing internet on this virtual router.

5.1 PfSense certificates

  1. Go to System / Cert. Manager / CAs and click the Add button.
  2. Name the certificate authority (VMlab-CA) and change Method to Create an internal Certificate Authority. The form will change, fill it out as the image below and click Save.
