Port mirroring means that all the traffic passing thourgh a virtual switch is being
mirrored to another switch port. This way it is quite easy to debug possible problems
and see what is happening on the lab network.
Network In my previous post I listed all the networks lab should have. To create bridges in Proxmox Webui go to:
Firewall transit network:
Node -> System -> Network -> Create Linux bridge
vmbr1 (fw <-> host) vmbr2 (fw <-> client networks) Client network:
Node -> System -> Network -> Create OVS bridge
vmbr5 (clients) Now we have everything we need in this stage and we can proceed to firewall install.
Having your own home lab is great! Building and breaking stuff in your own
environment is also a good fun. I’ll use my lab to try things out and to gain
more understanding of different attack methods and how to mitigate those. In
this series I’ll walk you through how I built my own lab.
