How to use "conduit permit ip host" to allow acces to any port ?

I have a user who need to access one particular IP on my network. I have assigned public IP to that computer but I don't know how to add a line to my PIX515 to allow access to that particular user IP (public IP) to access any port on my internal computer.
I have tried:
           conduit permit ip host
           conduit permit ip host
         conduit permit ip host

but firewall won't accept it.
It's erroring like this:
ERROR: Source address,mask <,> doesn't pair
Please help
