7. Create a record in Route 53

Create a record to home ip

Go to AWS console - Route 53 - Hosted Zones - Select one - Create record.

Input subdomain name, type A and home router's public IP address.

Test connection

Test after some time. A DNS propagation takes time. In my case, it took seconds though.

nslookup auth-dev.ourcompanylunch.com

or

curl auth-dev.ourcompanylunch.com
