Configure firewall in Norton 360 so that I can participate in Webinars?

I just purchased a new laptop preloaded with Windows 8. I also purchased Norton 360. I need to be able to participate in Webinars. However, I cannot figure out how to configure the Norton 360 firewall to allow the GoToMeeting application to execute. Any ideas?
