Overview

Default, the VMs are created in a VPC that cannot communicate with a remote private network. Therefore, to access the remote private network from a VPC, the GreenNode private VPN service creates a Virtual Private Network (VPN) Site-to-Site and configures routing traffic through this connection. Besides that, this connection is secure connection and safe cause using the IPSEC algorithm for authentication and encrypting data at two terminal VPNs local and remote.

Connection Site-to-Site VPN supports connecting with Protocol Internet Protocol security (IPsec).

Connection between sites

To understand more about the connection between sites, let's take a look at detailed describe

For example, we have 3 network sites, that are Hồ Chí Minh (HCM03), Hà Nội (HAN01), and Private Network (on-premise), each site already setup VPCs

Region HCM03 has VPCs:

  • VPC1 (10.1.0.0/16);

  • VPC2 (10.2.0.0/16).

Region HAN01 has VPCs:

  • VPC1 (172.16.0.0/16);

At Site On-Premise has network:

  • 192.168.1.0/24

  • 192.168.2.0/24

  • 192.168.3.0/24

Create VPN Connections:

  • VPNGW-01 of HCM03 <> VPNGW-01 of HAN01;

  • VPNGW-01 of HCM03 <> Router of On-Premise;

  • VPNGW-02 of HCM03 <> Router of On-Premise.

After finishing create VPN between above connections:

  • HCM03 VPC01 includes route 172.16.0.0/16 of HAN01 and 192.168.1.0/24 of On-Premise System.

  • HCM03 VPC02 includes route 192.168.1.0/24 and 192.168.2.0/24 of On-Premise System.
