Change default Web Publishing URI (NAS326)

Hi. I have problems with my NAS326 to use the Web Publishing.

I try to find the form to change the default  http://xxxxxx:5000/MyWeb/Sharedfolder   to external access throug using a http://xxxxx/

I configure my NAT router ports to redirect from port 80 to port 5000. And this part work fine, but I need to redirect directly to /MyWeb/www/  without I need to write this path in main URL.

In resume:
I HAVE:    http://xxxxxx/MyWeb/www/
I WANT:   http://xxxxxx/

Thanks.
