Ubuntu Security :: Iptables To Allow HTTPS Connections Only?

I have tried to configure my iptables to allow only HTTPS connections to the internet. Unfortunately, I didn't get that to work. I configured it like this:

Quote:

iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -t filter -p tcp --dport 53 -j ACCEPT
iptables -A OUTPUT -t filter -p udp --dport 53 -j ACCEPT

[Code]....

Of course I am only trying to access websites via HTTPS Still, I was wondering if HTTPS somehow under the hood requires the HTTP port to be open or if my rules are in some other way wrong.

ps: I got the rules from that website: [URL]
