General[edit]

The space of "To LABaki" is connected to university's infrastructure with a 100BASE-T line. Internet is provided by the university network and is used for client needs. Although university supports only IPv4, we have full IPv6 support (even one-stack is working) through 6to4 with relay to GRNET.

All Internet services of hackerspace are not served inside the university but instead a leased server in a commercial datacenter is used.

Layer 3 Topology[edit]

At IP Level network is divided in three zones.

  • LAN Trusted Which is used by all pc's that are wired on the network.
  • WiFi Guests That is for those connected through AP, and it has very limited access on network infrastructure.
  • DMZ Where permanent services are hosted in isolated environment for increased security.
