Opening ports in firewall

In order to access recorded lectures from her University, my daughter has been given the following instructions.

"You may have a firewall in place which is blocking access to the recordings. You will need to check that ports 8080 and 8443 are open (google how to do this for your particular system)."

I run Avira on all our machines and have attached screen captures of the dialog boxes I worked through trying to follow some general instructions I turned up with Google but the rule definition seems to want a lot of information I don't have.

I'm chasing the Uni tech people but it occurred to me that I may just be missing something obvious, that is obvious to someone who knows how such things work.

If anyone can get me over the present road block I'd be very grateful.  I also had a look at our router, which talks about port forwarding and have included a screen shot of its configuration page but the term forwarding didn't quite make sense in this context.

Where to from here?
