Open a HTTP port on Amazon EC2

I have a Tomcat 7 instance running on port 8080, and would like to run Jenkins on a different port. Another alternative would be to change the Jenkins URL.

How do I add an entry to the list of allowed ports?

I have tried running: sudo /sbin/iptables -A INPUT -p tcp --dport 8181 -j ACCEPT, but in the AWS console it shows only these ports:

0 - 65535       0.0.0.0/0
22 (SSH)        0.0.0.0/0
80 (HTTP)       0.0.0.0/0
443 (HTTPS)     0.0.0.0/0
3306 (MYSQL)    0.0.0.0/0
8080 (HTTP*)    0.0.0.0/0

Is it possible to add a HTTP port (8181) via the AWS console?

Update:

I already tried adding a custom TCP port, but then it doesn't get the HTTP protocol, and when I select HTTP, I can't specify the port!

As per Agat, double check the firewall settings on the server itself. I had the same issue with port 8090 and then I realised I needed to open it in the Windows firewall.

In EC2 console, look for the column "Security Group" of your instance. Then go to option "Security Groups" above "NETWORK & SECURITY" in navigation menu on left. It will show up the security group you saw before. Click on it, it will show a split screen where the one is above has 2 tabs: Details and Inbound. Go to Inbound, in port range input 8181 and source the ip you want to allow incoming access to instance. Don't forget to apply changes.
