Stumble It!

Smoothwall can be used on  any Pentium-class PC  and it comes pre-configured to stop all incoming traffic that is not the result of an outgoing request. The new  “Purple network” interface keeps wireless clients like laptops safely off the main network. Smoothwall supports  64bit, for Intel Core 2s (and other Intels with 64bit support) and 64bit Athlon chips.

Key features of the firewall are:

• Compatible with wide range of hardware/systems
• Flexible & Easy to Use
• Multiple network zones – Client Local Network (Green), De- militarized Zone for hosting servers (Orange), Wireless Client (Purple) and External (Red).
• Comprehensive reporting & logging capabilities
• POP3 Email antivirus proxy
• Web proxy support
• Snort IDS support
• Static and dynamic DNS support
• Remote Access and VPN support
• DHCP and Network time server support
• Powerful traffic graphs and bandwidth bars
• Inline Proxy support for Instant Messaging (MSN, ICQ, Yahoo!, AOL) & VoIP with logging capabilities
• Universal Plug n Play Support (UPnP)
• Bandwidth Management
• Real-time Graphs & per IP Traffic Stats
  
• Update system
• Outbound traffic blocking with time-based controls

Smoothwall is using colours to differentiate the networks. The network interfaces are designated accordingly.

The Workshop setup could look like this:

Step 1: Smoothwall Installation

Please download the current release here.

Smoothwall Express  runs on a workstation with a bootable CD-ROM drive. After booting it will  automatically check  the workstation and hardware components. During the installation process Smoothwall will delete all data you may have on your hard disk. So, before you start
the installation, ensure that all valuable data is safely backed up. The following screen will be displayed:

Please select the security policy you would like to use.

The following policies are available:

Open:
Smoothwall Express allows all outgoing requests.

Half-Open:
Smoothwall Express allows most outgoing requests and blocks
potentially harmful requests

Closed:
Smoothwall Express blocks all outgoing requests. Anything to be allowed must be
explicitly enabled.

We are using the „half-open“ policy.



Network configuration



We are using the “GREEN+RED” configuration:

The “GREEN” interface card is connected to the internal network and the “RED” interface to the external network. If you have a different setup or hardware, please use the configuration accordingly.



Let’s configure both network cards.



We are using static IP addresses for both interfaces.





Please setup the DNS and Default Gateway accordingly.



Hit “Finished” to continue.



Enter Smoothwall admin password. You’ll need it for logging into the web interface later.



Setup the root password next.



The setup is now complete. Please remove the CD and restart Smoothwall.



Smoothwall starts with a nice screen…



… and loads the configuration.
