Disabling Smart Firewall doesn't work

I'm trying to connect my Windows 7 PC to my PS3.  It looks as though the firewall is getting in the way.  I've switched off the Smart Firewall in the Norton application.  However, when I go to Control Panel>System and Security>Windows Firewall I'm not able to change anything because it still says that "These settings are being managed by vendor application Norton Internet Security".  This means that I can't access certain advanced options that will allow me to connect my PS3.

 

Please help!
