For example, there are two CIDRs in the same VPC on AWS. One of them is public and one is private. They are in the different segment.

# Public Subnet CIDR
10.124.42.0/27

# Private Subnet CIDR
10.124.43.128/25

If want to connect from public to private's network, is it possible?

Yes, subnets in your VPC can communicate by default.

It is possible to provide a custom security configuration to control inbound/outbound traffic using Security Groups or Networl ACLs features.

It is also possible to configure routing using Route Tables.

Please refer to the official AWS documentation, which covers this topics in detail.
