MOTIVATION
My fiancé and I are getting married in October.
Through the course of this semester, I hoped
to design and implement a home network
that could be used in our new home.
I wanted this project to have real-world
applications that would be useful in our
home.
It was important for me to use the knowledge
and skills I had to learn something new or do
something I have never done.

PROBLEM STATEMENT

Problem:


The need for a secure, reliable home
network
Specifications:

Filter incoming ISP WAN data
through an open-source
firewall/router into a LAN
environment
7
PROBLEM STATEMENT

Specifications continued:






Web filtering – content, URL
Access restrictions
DHCP for the LAN
Report generating capabilities
Secure wireless networking
Centralized network storage for media and
backups
8
PROBLEM STATEMENT

Specifications continued:



Inexpensive, networked media center
Media center should stream from NAS
Control media center with iOS devices
9
ASSUMPTIONS



Home owner wants a media center
and central storage
Home has an ISP
Two PCs needed:



User has access to an unused PC
(OR)
User can part and assemble a PC (or
both)
User owns a Raspberry Pi
10
ASSUMPTIONS

Smart device(s) on hand for remotely
controlling XBMC – iOS, Android


App store, Google store account
The user is capable of compensating for
lack of knowledge by using the
resources available at their disposal

HDMI
2 USB ports
RJ45 jack
21
PROPOSED SOLUTION

What you’ll need:
22
PROPOSED SOLUTION

XBMC



Open-source media center solution
Distributions: xbian, Raspbmc,
OpenELEC
OpenELEC boots faster & has snappier
menu navigations on the Pi than
Raspbmc
23
PROPOSED SOLUTION


of network)
24
RESULTS
The home now has a fully-functional
network with a perimeter
router/firewall, central storage for
backup and media safekeeping, a
cheap media streaming solution, and
secure wireless networking
(For images and demonstration, see
video)
