iptables rules whitelist web traffic

view story

http://serverfault.com – I wrote the following iptables rules. My main intention was to do these things allow ssh traffic to any machine allow web traffic(http,https, and some ssh) to a select number of websites(effectively a whitelist) allow all traffic to 192.168.0.x (machines in my subnet) allow all traffic with the loopback interface don't mess up the current connections So i wrote the following set of iptables rules. Which leads to not being able to access anything anymore, I messed up..:( How do I fix this ? I'm not good at all with iptables, I'm reading documentation about it, but haven't been able to figu (HowTos)
