Firewalls and VPN/IPSec

General information


Lecturer: Lauri Võsandi


In this course we will attempt to set up a network similar to a corporate network with multiple offices, eg

Our virtual company's story is based on Mom's Friendly Robot Company.

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.


If you don't know what to do pick a topic from the services list below. Send your SSH public key to Lauri and state which service you want to take care of.

  • Get the service up and running (10p)
  • Configure Let's Encrypt certificates for your service if applicable (10p)
  • Add your service to monitoring at (10p)
  • Enable log forwarding to (10p)
  • Configure your service to send e-mails ( if applicable (10p)
  • Keep the service up and running through the semester (up to -20p)
  • Keep the bad guys out from your servers (up to -30p)
  • Have a disaster recovery plan (up to -20p)
  • Configure layer3 firewall (10p)
  • Configure application firewall(s) if applicable
  • Configure your laptop to connect to intranet using OpenVPN and IPSec (10p)
  • Configure your mobile device to connect to intranet using OpenVPN or IPSec (10p)
