Work in progress

Thesis notebook

I use this homelab for my thesis work too. The research question, the method and the results are not written yet, so this page only holds what is true today. I will add notes here when they are ready to share.

Where the thesis work runs

The thesis environment lives in LAB_TEST, VLAN 20 on the Sophos Port3 trunk. The Kali Red and Kali Blue VMs and the thesis test guests belong there, away from my management interfaces and from the internet.

Sophos drops and logs everything leaving that VLAN with a rule called DROP_LAB20_OUTBOUND. When I tested it on 6 November 2026 from a container tagged into VLAN 20, the guest got a DHCP lease, but every ping failed, the connection to the Proxmox management port did not open, and Sophos logged drops for DNS on UDP 53 and TCP 853. The interface also had an IPv6 link-local address, so the test shows the IPv4 drop working; it does not prove the VLAN is sealed in every direction.

I chose this layout so a thesis experiment cannot reach anything it should not, and so I can restore every guest from a snapshot and run the same test again.

Status

Work in progress. The thesis title, research question, methods, metrics and results will appear here once they exist. Nothing on this page is a result yet.
