Aurora rds -> MySQL rds cross region replication

Question

I am looking to do cross region replication. I know exactly how to do it but want to do it in safest way possible from a networking perspective. I will call set external master but I don't want my instances to be publicly accessible.

How does amazon do cross region replication via control panel securely without using publicly accessible option for rds

The reason I am using MySQL on other region is cost savings. Since it isn't aurora to aurora I need to use set external master and setup replication manually.

Do I just put everything in same VPC?
