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.

Offices

Headquarters

Gateway: 193.40.194.220

DNS: 193.40.0.12, 193.40.56.245

Public IP address (eth0): 193.40.194.160/24

Internal IP address of the physical server (eth1): 172.16.1.1/24

Management network IP address (eth2), accessible from robotics club: 192.168.12.10


Team members: Keijo, Anton, Mohanad, Etienne

Services:

  • BIND9 as public DNS server, also figure out what domain name we should/can use
  • domain controller, at this point primarily for user accounts (Keijo)
  • nginx web server, for company's homepage (Anton)
  • SMB/CIFS fileserver, join to domain (Etienne)
  • VPN server for other subnets, presumably OpenVPN

Research & development

Gateway: 193.40.194.220

DNS: 193.40.0.12, 193.40.56.245

Public IP address (eth0): 193.40.194.161/24

Internal IP address of the physical server (eth1): 172.16.2.1/24

Management network IP address (eth2), accessible from robotics club: 192.168.12.11

Devops

Gateway: 193.40.194.220

DNS: 193.40.0.12, 193.40.56.245

Public IP address (eth0): 193.40.194.162/24

Internal IP address of the physical server (eth1): 172.16.3.1/24

Management network IP address (eth2), accessible from robotics club: 192.168.12.12

Team members: Arti, Meelis Hass, Artur O, Sheela, Ilja (exchange)

Services:

  • IRC, for chatting
  • Certificate management for roadwarriors
  • Monitoring software of your choice to make sure that services are up and running
  • E-mail for sending notifications from monitoring software at first
  • Later, in the beginning just monitor public services: OpenVPN connection to headquarters
