The LASAT Masquerade 2 (1998) and later Masquerade PRO (1999) was created by LASAT Networks, as part of a product line of self-contained SOHO all-in-one servers (firewall/NAT/router, mail server etc.)
Unfortunately the company went bust, so very few of these devices were ever shipped, but they still fulfill their original purpose very well.
The Debian project still uses two Masquerade PRO as MIPS autobuilders.

Serial Cable
If you want to do any debugging on your Masquerade, you'll need a serial cable. The cable conncets to the 6-pin (only 3 used) header on the PCB (J2). This header is not mounted on all boards, if it is not you'll need to mount the header plus an RS-232 buffer (IC34), see the design specification for details on which part to use. The cable design can be found here.
EUCP
The LASAT devices have a "service mode" where you can use a special tool to upload a new kernel to the device. The protocol used is called EUCP, and is documented here. Tools to create the images and upload the files are available on the Debian instructions page, see Links.
