So how can I find out which ports are being blocked, and where?

I'm using Earthlink as the ISP. When I use ISDN, Outlook can't connect.
When I use the regular modem, it works fine. I doubt Earthlink is
blocking ports on just ISDN which is a business class line which, if
anything, should have less blocking.

Any ideas? Thanks!
