I thought the above would make for simple browsing on the net but I can't ping anything, can't acess a simgle page on the net. Ideas ?

Well, you've blocked name resolution and who knows how many other useful ICMP packets. 'http/s' isn't the only thing on the wire.

Just to confirm:

host www.google.com

(or 'nslookup' if you don't have 'host')
