# VPN

NeevCloud supports Site-to-Site IPSec VPN between two isolated networks using VPNaaS (VPN as a Service) with IKEv2 / IPSec / AES-256 encryption.

### Prerequisites

* Two networks created with separate subnets
* One router per network with an external gateway assigned
* At least one VM running in each network
* Note down the **External Fixed IP** of each router from **Networking > Routers**
* Note down the **External Fixed IP** of each router from **Networking > Routers**
