====== Base Infrastructure ======

===== Overview =====
The base needs infrastructure to be operational. \\
One key basic needs of every human beeing besides a room, power, water and Mate is of cause Internet

When we had the go to move into the room there was already a Internet connection and we are allowed to use it. \\
The three parties in the building should be segmented from each other.

The resulting infrastructure description should be generic and the concept usable by other Hackerspaces or even smaller companies.

===== Concept ======

The WAN port of the Fritzbox is unusable, because it is only usable for DSL. We have FTTB \\
Every party will get one port on the Fritzbox.

The fritzbox must stay at the base. It will be a shared environment, but it cannot be avoided for now. \\
The Qnap needs to be moved to the top floor. \\

===== House segments =====
Fritzbox \\
192.168.1.0/24 \\
This is the shared network and it belongs to the building itself. \\
The Fritzbox itself is managed by trinitor \\

Every floor can have 10 static IPs in the shared network \\
1st floor = 192.168.1.10 - 19 \\
2nd floor = 192.168.1.20 - 29 \\
3rd floor = 192.168.1.30 - 39 \\
There is also a DHCP range, but it is more for emergency use.

==== /dev/base Structure ==== 
Our /dev/base port will be connected to a Proxmox server = our virtual environment. \\
This port will be dedicated to a VM where we have a firewall running. In this case a pfSense. \\
The firewall VM will have three virtual NICs. \\
1. WAN = Fritzbox = Internet \\
2. virtual switch = Server = vSwitch with no physical NICs attached. All VMs will be connected to the vSwitch. The traffic will stay inside the host. \\
3. physical switch = the /dev/base internal network \\

The firewall will protect the /dev/base infrastructure from the Internet and the other parties in the building. \\
The VMs are in a segmented VLAN to have them also controlled in a better way.

==== Virtualisation (main) ====
There are some options (ESXi, XenServer, oVirt, ...), but the simplest one seems to be Proxmox. \\
An old Dell Notebook with an additional USB NIC will be used for now. \\

==== Virtualisation (secondary) ====
There is also a second Proxmox server with only one NIC. \\
It is running on a MacMini and will only be turned on if needed to safe power. \\

Proxmox runs on Apple Hardware, but there are some driver issues. \\
Disable modules: \\
<code>
cat >> /etc/modprobe.d/pve-blacklist.conf <<EOF

==== Wireless ====
The Access Point will broadcast three SSIDs. 
|/dev/base PSK |WPA2/AES Personal   |fallback       |
|/dev/base     |WPA2/AES Enterprise |member network |
|/dev/guest    |WPA2/AES Personal   |guest only     |
For not both share the same subnet and are not segmented. \\
Advantage: might be easier to change the password, implement radius \\

Longterm there should be a Freifunk for guests

Segmenting the guest network means we have to use VLANs in Proxmox, pfsense, switch, and access point. \\
Without VLANs we can just take the cable from the AP and plug it into the Fritzbox. \\
With VLANs we have no easy fallback in case theres an issue with the Proxmox server \\
