Hi,
You can use the GUI to check what ports are default open. Simply open a web browser with your IP address of the router, you will then be presented with a login prompt. Login with your admin credentials.
or from CLI (Command Line interface) type "sh ip port-map"

Sorry my mistake, you can use the GUI only if you have the SDM installed on your computer. This can be downloaded from Cisco.com for free.
