Can anyone confirm at DTI only use port 443 for communication with Winchill?

[LSivertsen]

We are going to use a reverse proxy between the Desk Top Integration client and the Windchill server.

Therefore we want to know if DTI only use port 443 to communicate with Windchill.

When we ask helpdesk, they say that DTI uses port 445, but if we close port 445 DTI still works fine.

DTI communicates with Windchill using http requests. It will use whatever http port you've configured Windchill to use. If you've configured Windchill to use https on port 443, then DTI will also use 443.

When viewing today, CS Article CS81708 incorrectly identifies port 445 as the primary communication source for Windchill Desktop Integration. DTI does not use port 445, it only uses standard HTTP and HTTPS. PTC Technical Support will be updating this CS Article ASAP to remove the use of port 445 for Windchill Desktop Integration.
