Are you wanting to deny all access except the two webpages you listed or are you wanting to deny access to all ports except the ones used for browsing the internet. If you deny all access to all webpages except the ones you listed and allow ports for web browsing then you will either only have access to those pages or all pages. If you want this to be for all other users only access to those pages and yourself access to ports allowing you to browse normally then that is different. Can you clarify. Do you need port 443 access, for https. Do you need access for e-mail, (465, 587, 995, 997) etc.
