IPCop firewall part I: installation.

If you want to protect your network from the internet, one of the things you need is a firewall, in this tutorial I will show you how to install ipcop firewall, for this all you need is an old pc and the free ipcop installation software. IPCop doesn’t require a lot of hardware to run, it will run on 64M of memory although I recommend at least 128M, it all depends on how many services you’re planning to run, also it doesn’t require a lot of hard drive, unless you’re planning to do a lot of logging, and web cache, and finally processor speed it’s not really that important

IPCop is a Linux distribution which aims to provide a simple-to-manage firewall appliance based
on PC hardware. IPCop is a Stateful firewall built on the Linux netfilter framework. Originally a
fork of the Smoothwall Linux firewall, the projects are developed independently, and have now
diverged significantly. IPCop includes a simple user managed update mechanism to install security
updates when required.

IPCop’s main feature is as a firewall system for small offices or home networks. It is free to
use and therefore the only costs in getting it running are the hardware. Here are some of the
IPCop features:
4 interfaces with typical behavior:
1- GREEN: Inside network
2- RED: Outside network/Internet
3- ORANGE : DMZ (accessible from in and outside)
4- BLUE : inside network for wifi (connect an Access point to this interface)

For this tutorial I’ll be using the basic GREEN+RED network configuration, which only needs two cards.

Here are some of the core services running on IPCop.
1- DHCP client / server
2- Dynamic DNS
2- Host list settable from web interface
3- HTTP / FTP proxy (squid)
4- IDS (snort) on all interfaces
5- Log local or remote
6- NTP client / server
7- SSH server (PSK or password)
8- Traffic shaping (red interface)
