Amazon EC2 – Allowing Web Access to Windows Server 2008 Instance Running Tomcat

amazon ec2amazon-web-serviceswindowswindows-server-2008

The instance I choose was the following:

Basic 64-bit Microsoft Windows Server 2008 (AMI Id: ami-d9e40db0)
Microsoft Windows 2008 R1 SP2 Datacenter edition and 64-bit architecture.

I have installed Tomcat + an application and AM able to see the website when I access the local IP thru IE (in the EC2 instance).

However, when I try accessing it as:

* the assigned Elastic IP
* the ec2-999-999-999-999.compute-1.amazonaws.com

from the EC2 instance itself or from outside, it doesn't work. IE says:
Internet Explorer cannot display the webpage

I've tried:

* disabling the Firewall -> no luck
* waiting for a bit -> no luck

I can't ping the machine assigned Elastic IP either.

The allowed connections (as seen in Amazon's Management Console) is as:

Connection Method  Protocol From Port     To Port   Source (IP or group)
SSH              tcp               22          22   0.0.0.0/0
RDP              tcp             3389        3389   0.0.0.0/0
DNS                 tcp            53          53   0.0.0.0/0
DNS                 udp            53          53   0.0.0.0/0
HTTP                tcp            80          80   0.0.0.0/0

I figured it out... I wasn't disabling ALL of the Windows Firewalls!!

There are 3 in Windows Server 2008

Domain Profile

Private Profile

Public Profile

Disabling in each made it work... of course, at production time I will set these appropriately...
