local site with IIS and DW CS6

I have configured IIS (Windows 11 24H2) as server for a local site of mine, let's say "mysite", with the following properties:

Site: mySite,

Application pool: mySite (added automatically),

Physical path: D:\mySite,

Type: http,

Host name: mySite,

Port: 8080,

IP: All unassigned,

With those settings I can browse the site starting from the home page at http://mySite:8080/ 

Then, I've tried to set the site in Dreamweaver CS6 too, with the following properties:

Site name: mySite,

Local folder: D:\mySite,

Server name: IIS,

Connect using: Local/Network,

Server folder: D:\mySite,

web URL: http://mySite:8080/ 

However, when I try to test a page in Dreamweaver with "Preview in browser" feature, the browser gets the local file (file:///D:/mySite/folder/subfolder/TMP1g3szin.htm), instead of the web address (http://mySite:8080/folder/subfolder/TMP1g3szin.htm )

(the temp file name is because I use the option "Preview using temporary file". I have also tried with the option disabled, and got the same results)

Am I missing something?
