You should be able to access the router using a web-interface. At this point, there should be information about what port(s) are being used.

You will need a conversion calculator like the one in Windows. To find out the standard services on various ports, check out the list at <a href="http://www.iana.org/assignments/port-numbers">IANA</a>.
