Tests do not run when using the webpagetest-server AMI

Sad Tests do not run when using the webpagetest-server AMI
Hi,

I launched an instance with the AMI webpagetest-server-2014-11-25 - ami-9978f6ee.

User data:

Code:
ec2_key=AKIA
ec2_secret=ABC
api_key=blah
headless=0
archive_s3_server=s3.amazonaws.com
archive_s3_key=AKIA
archive_s3_secret=ABC
archive_s3_bucket=test_wpt_results
archive_days=30
EC2.default=eu-west-1
EC2.eu-west-1.min=1
EC2.eu-west-1.max=10
EC2.eu-west-1.securityGroup=same-as-server
EC2.eu-west-1.subnetId=same-as-server

The AWS key can manage EC2 and S3.

One launched, I open the webpagetest webui, and run a test with Chrome in the default region (Ireland), and get the "Waiting at the front of the queue" message indefinitely.

I see that a Windows instance was started automatically. I can login with RDP, wptdriver.exe is running and it checks for tests. In wptdriver.ini, the [WebPagetest] section contains no url nor location key, but ec2=1.

Does wptdriver.exe writes logs somewhere, so I can at least check where it is polling for jobs ?

I also tried running tests us-east-1 and eu-central-1, and also start a server in these regions.



Edit

So I checked the code of wptdriver, especially wpt_settings.cc.

It calls http://169.254.169.254/latest/user-data to get the server ip.
So I dit that on the Agent instance and noticed that wpt_server contains the public IP of the server. I expected the private IP.

So I added a rule in the Security Group to accept connections from the public IP of the agent, and it works fine now.

It's more an EC2 question than a WPT question, but how would I configure my security group to only allow connections from public IPs of each new agent ?

Thanks,
Nicolas
