Opening up these applications (especially Java) to allow all ports on a public network could be a security exposure. This is why it is important to set your local LAN to private if it is not set as private currently. I don't use McAfee but I would hope that it allows different settings for private and public networks (other firewalls do). If so, you could open these ports for private networks only.
