I beleve the 501 has the PDM (Pix Device manager) you will need to enable it though
in this example your network is 192.168.1.0. This command lets any computer from 192.168.1.0 connect to the PIX (if they have a password)
telnet to the router
enable (your password)
config t
Show version
(read below)
http server enable
http 192.168.1.0 255.255.255.0 inside
If you see both of these (any version)
Cisco PIX Firewall Version 6.3(5)
Cisco PIX Device Manager Version 3.0(4)
than the PDM is installed (web interface)
PIX> enable
