Installation of the CF Image using FreeBSD or Linux

As with MS Windows, the only requirement is a way of writing to the CF card either using a USB or IDE attached CF card adaptor. Under FreeBSD the image is decompressed using a combination of the gzcat and dd command line tools. Under Linux, gunzip is substituted for gzcat.

More detailed instructions are available on the m0n0wall website at

After the CF image is written, it's just a simple matter of removing the top cover from the net4501 and installing the CF card into its slot on the mainboard, remembering to replace the retaining post.

Booting m0n0wall for the first time

The detailed instructions on the m0n0wall website make reference to powering the net4501 and logging onto the box using Windows HyperTerminal or some other serial console software and setting up the network interfaces. This requires a serial null modem cable.

In reality, this is unnecessary, since by default the Net0 interface of the net4501 is assigned as the m0n0wall LAN interface and given a default IP address of (Subnet mask DHCP is also enabled.

Either plug LAN0 into a Hub or Switch with a standard Ethernet straight-through cable (MDI) or into the network interface of a PC with an Ethernet cross-over cable (MDI-X). Assuming you have no other DHCP server on your LAN, you can set your PC's TCP/IP properties to 'Obtain IP address automatically' and your PC will be assigned an IP address by m0n0wall's DHCP server. If you'd rather set your IP address yourself, use an IP address between and with a subnet mask.

To confirm everything is working, open a web browser and go to and you should be rewarded with a login prompt. The default username is admin and password mono, both lowercase and containing no numbers. Now you can update the IP address of the LAN interface to suit your own network.
