Hello,

I have Verizon FIOS at home.  The firewall on my router is set to maximum protection but explictly allow rules for traffics.  

I am having trouble when playing a video from certain websites.  Is it possible to determine what ports are required for me to setup the rule to connect?

Thanks.

You could use Wireshark http://www.wireshark.org/ to monitor your network traffic.  All you need to know is the IP of the site you are connecting to and wireshark should also show you the port number it is trying to use

Yes , It is possible. you can judge it by many ways
1. you use Network Traffic viewer tool  http://www.nirsoft.net/utils/network_traffic_view.html
2. you can use netstat -an which inbuilt command but above tool  will give live output of data outgoing and incoming. then you will notice at which port data is going out. I meant, you can see the port by which your browser or any software getting video steaming.
3. currports tool http://www.nirsoft.net/utils/cports.html.
4. you can see firewall logs by configuring your firewall settings , if you have installed any internet security
5 wireshark which for advance user. which will give you full detail of packet.
