nmap is a relatively easy to use command line tool for port scanning.  http://nmap.org/download.html

You can also use netcat and superscan http://www.thenetworkadministrator.com/netadmintools.htm

You can also do a live scan of the external IP address of this router at grc.com. That is another helpful source.
