If USWest is your ISP, then your modem is configured to get an IP for itself. 
What you need to do is connect to it either via telnet or the serial cable that
was provided (serial->RJ-45).  First check your NAT by typing 'show nat' (no
quotes).  This will give you your Internet IP (called Inside Global Address). 
With that IP enter the enable mode by typing 'en'.  I pray that you have
passworded this mode, cause if it isn't then someone could go in and screw your
configuration up so you won't be connected anymore.  What you want to do is set
a fixed NAT entry into the NAT table.  This is done via the 'set' command.

example:
set nat entry add 10.0.0.4 80 216.160.217.118 80 tcp
will redirect any port 80 tcp requests to 10.0.0.4 port 80 (default port for
Webservers)

This adds an entry:
set nat entry add (inside IP) (Inside Port) (Routers External IP) (Router Port)
(mode either tcp or udp)

This removes an entry
set nat entry delete (inside IP) (Inside Port) (Routers External IP) (Router
Port) (mode either tcp or udp)

last but not least do a 'write' to save the changes to the nvram.  This way if
you lose power or unplug the router it will still remember this information.
