AWS securing outbound communication in private subnet

I've a private subnet in AWS that needs to be locked out from Internet access. But the instances in this private subnet need to access specific set of hosts (say update.java.com, update.ubuntu.com etc). Obviously the IP address associated with these hosts are dynamic. Does Palo Alto Networks Firewall (or any other solution) solve this scenario? If so, please provide pointers.

Hi Foobar,

 

You can create custom URL and allow internet traffic for those URL for a specific subnet.

 

Please refer the following doc.

Thanks Hardik.

 

I'm assuming this solution is available in Palo Alto Networks VM-series Next-Gen Firewall Bundle 1/2 in AWS Marketplace. Please confirm.

PAYG2 will have support for URL Filtering

If all you need to do is create a customer URL category and define the URLs then you shouldn't need a URL filtering license for that. But if you want URL filtering then PAYG2 is the way to go there.

Thanks.

 

Is there a template readily available to deploy a simple solution for this usecase in AWS?

From link, I guess I'm trying to implement "Use Case: Secure the EC2 Instances in the AWS Cloud" section. Looking for a template that I leverage.

 

Thanks.
