Reroute traffic from CloudFront distribution to another domain URL

Question

Hi,

I need to solve an interesting case related to CloudFront rerouting. Earlier I setup a S3 bucket which is used as a origin in CloudFront and I can fetch the data using this CloudFront Distribution url. Now I want to redirect all my request coming to xyz.cloudfront.net on port 5000 to be routed to abc.non-aws-domain.com. 
**xyz.cloudfront.net:5000/rest-info/doc** —> **abc.non-aws-domain.com:443/rest-info/doc**
The problem is I see now that xyz.cloudfront.net:5000 does not exist. I tried to use ALB for this purpose but I see that after creating it and some rules I still see with curl that there is no rerouting.
What did I miss? Should I use another solution for this?

Kind regards,
Ivan Manzhulin

Hello.

As you know, CloudFront listens on ports 80 and 443, so accessing it on port 5000 will result in an error.

I think it is possible to route using ALB.  
Have you configured the ALB redirect action?  
https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html#redirect-actions

For example, if you configure the following settings, when an access occurs at "http://ALBDNS:5000", a redirect will occur to "google.com".

Thanks, it worked. I forgot to create a custom VPC with public subnets (I was using a default one before).
