I have select allow http traffic when I create the instance and allow the tcp:80 traffice in VPC network setting, I also enabled port 80 in iptables, however I still cannot use netcat to connect to the 80 port, it's always "Connection refused". Anyone knows how to make it? Here is what my VPC setting looks like: My VPC setting, and my iptables looks like: enter image description here
Update: Sorry, my bad. I found I need to install Apache first then nc can find the 80 port opened.
