Is there any sw I can use to see what ports on my PC are open/closed and
which apps are using the ports?

Thanks to all. BTW, I have no trouble with my router accessing anything
outside my network. The trouble appears to be the PC - I am hoping the
suggestions made will check the PC ports - not the router ports.
