     Maybe the command syntax for the Cisco 675 will help.  A
nat entry is entered thusly:

set nat entry add <inside, private IP here> <port number> <outside IP here> <port number> tcp  <-----or whatever protocol at the end here

example:

set nat entry add 196.168.192.3 80 206.184.73.6 80 tcp
(for a Web server, e.g.)
