Accessin' packages

Hello to all.

I've installed mowes portable II coming from several wamp's that i disliked.
I've a new home server on win xp that has replaced an old macintosh.

I like mowes, seems good and compact, all ready to work with no hassles...

I've installed some packages too, just to test, but i've a little problem.

I would like now to use the default /start/index.php to access the installed packages.

To gain access from the internal network is not a problem, the problem starts when accessin from outside.

If from outside i call my dynDNS name i can reach the /start/index.php with no problems
(http://mydynDNS.some.thing -> http://mydynDNS.some.thing/start/index.php)

If on the /start/index.php page i click on phpinfo i get correctly /start/phpinfo.php page.
The document root seems good (Document Root is: C:/mowes_portable/www)

If i click on a package such as PHPMyAdmin the pages refers to http://192.168.0.6/PHPMyAdmin.
192.168.0.6 is the server ip on the home lan...
the same for all the packages installed.

What have I to change to make it point to http://mydynDNS.some.thing/PHPMyAdmin ?

If I write down on browser http://mydynDNS.some.thing/PHPMyAdmin i get the PHPMyAdmin page, so the problem is related to  /start/index.php.

Many thanks for any help...
