NW 2004's getting port 443 on unix to work ??

I have loaded 2004s portals in my DEV system, (server at our data center at another site)every thing works ok, change the port from 50101 to 443 in VM but can not get to the server on that port. I believe it a UNIX problem because I know that ports under 1024 on unix are reserved.

How can I get Unix to now let my portales to use port 443.

Thanks for any help.
