I have a turnkey install through AWS with Ubuntu 10.4 using webmin version 1.580.
I wanted to open up ports 110 and 25 to route email and so i edited the ip tables in the linux firewall module and then tested the ports to make sure they are open. So when i tested them through a port scan they showed they were still closed. So then I thought well maybe I had to open the ports up in the Amazon control panel for the instance and open up the ports in the security group for the instance. So i had the following setup
110 (POP3) 0.0.0.0/0
In the iptables i had this setup
-A INPUT -p tcp -m tcp --dport 110 -j ACCEPT
So when I did a port scan again it still showed the port as closed.
So now i'm confused on why it keeps showing the port as closed even tho its open in AWS and on the linux firewall.
Did I miss something somewhere?
