the cisco pix device manager (pdm) is a browser-based configuration tool that lets you set up,configure, and monitor your pix firewall from a graphic user interface (gui), without any extensive knowledge of the pix firewall command-line interface (cli). pdm provides a management interface from windows nt, windows 95, windows 2000, or solaris web browsers. pdm limits access to the html interface to specified client systems within the inside network (based on source address) and is password protected.
