Planning the Project Specs

Goals:

- Two local subnets, Wired and Wireless

- Support Xbox Live

- Provide external access to my file server

- Limit all communication out of my network strictly to the applications and services I choose to allow (web traffic, mail traffic, ssh, xbox, torrents, etc)

- Improved stability over the over-the-counter home routers

- Shape traffic using ALTQ

Resources:

- For the Operating System, I’m going with OpenBSD 4.3 (STABLE)

- Putting to use my MaxTerm 8300B

EVE-M 800 mhz (x86)
256 MB of RAM
15 GB IDE hard drive (spare one sitting around)
D-Link USB Wireless Card (rum0 driver in OpenBSD) for local wireless traffic
Spare old 3com 10/100 Mbit NIC for local wired traffic

- For reference, I’m using “The Book of PF”.

This has been a great read and an excellent resource in the planning stages of this project for me. For anyone who doesn’t already have a copy, I can not recommend this book enough. Heres a link for picking it up from Amazon. (it’s probably be the cheapest part of this project)

The Plan:

Local wired traffic: 192.168.0.X/24
Local wireless traffic: 192.168.1.X/24
Provide DHCP services on both local interfaces
External Interface running DHCP
Starting with blocking everything [block all]
Designate IPs per server and personal computer on my network
Designate torrent ports to each of the personal computers
Initially just use WEP for proof of concept, later use WPA or even an authpf with a possible web interface for authenticating
Perform MRTG graphing if for nothing more than to see what I spend my bandwidth doing

Continue to Part 2.

I happened across your blog while looking for information on how to do almost precisely what you’re doing in this project. As I’m not very experienced (nay - no experience) with OpenBSD or FreeBSD, I was just trying to gather as much information as possible before I begin.

I look forward to reading more of your experiences with this project.
