Phoenix IT-100 Appliance

Phoenix IT-100 Appliance. Fanless 500Mhz Transmeta Crusoe TM5600. 128MB SDRAM. 32MB CF. 2 x Realtek RTL8100B 10/100 Ethernet Nics. 1 x Prism54-based 802.11b/g Wireless NIC. Stateful inspection firewall. 5-20 users. 70 Mbps (5K pps) maximum cleartext throughput. 10-14 Mbps IPSec VPN throughputs. Utilizing OpenWrt®  software, which also has a WebGUI and a comparable feature set as pfSense® but much less demand on CPU performance and memory capacity.

OpenWrt® is an embedded operating system based on the Linux kernel.


  1. The IT-100 does not have VGA. Console is through a DB-9 serial port with the following communication parameters: 38400baud 8n1.

Network Interfaces

See the picture of the back panel.

  1. WAN (ETH0 RTL-8139 10/100 Ethernet interface): The first RJ45 Ethernet port from the left.
  2. LAN (ETH1 RTL-8139 10/100 Ethernet interface): The four-port switch hub.
  3. OPT1 (WLAN0 PRISM-54 802.11bg wireless interface) with two built-in hidden diversified antennas.


Folloing are the built-in features of OpenWrt® running on the Phoenix IT-100. Many are managed by LuCI, the WebGUI.

  1. Web-based graphical user interface: LuCI.  See image.
  2. Iptables-based (netfilter) firewall.
  3. OpenVPN and OpenConnect VPNs.
    • IPSec (Strongswan) is also available but requires setup and maintained through command-line, as it is not integrated into LuCI.
    • The IT-100 is limited in its CPU performance and can only accommodate a few tunnels.
  4. LuCI built-in splash screen. Full feature captive portal CoovaChilli is available, but requires setup and maintained through command-line, as it is not integrated into LuCI.
  5.  Intrusion prevention systems (IPS) and intrusion detection system (IDS): Snort, which also requires setup and maintained through command-line, as it is not integrated into LuCI. Snort implemenation should be planned with consideration to the limited CPU performance of the Transmeta Crusoe TM5600 in the IT-100.
  6. Traffic shapper: sqm-qos. Qos can be installed and is integrated itno LuCI.
  7. Fail-over: ucarp, which requires setup and maintained through command-line, as it is not integrated into LuCI.

There are additional packages that can be installed if desired. However, space is limited on the 32MB CF, about 15MB available. And a reset-to-default will wipe out installed packages to return the IT-100 back to its original factory configuration.


The Phoenix IT-100 appliance has been employed at the following network locations to protect SMB (Small and Medium Business):

  1. SOHO (Small Office and Home Office)
  2. Captive Portal
  3. Branch Office
  4. VPN Endpoints
