Firewalls and VPN/IPSec

General information

ECTS: 4

Lecturer: Lauri Võsandi

Scenario

In this course we will attempt to set up a network similar to a corporate network with multiple offices, eg http://docplayer.it/docs-images/20/596222/images/25-0.png

We will use VPN software to connect subnets to each other and we will use VPN software to connect our personal computers to the intranet.

For this course we have 3 Sun servers, each with 16GB of RAM. In each server we should be able to create 3 or more virtual machines. As host operating system we will install Ubuntu 16.04 server. On disks set up ext4 on mdraid set up in RAID1 configuration.

For virtualization let's use libvirtd and virt-manager on your Ubuntu laptops. Adventurous might want to try to set up Kimchi web interface.
