📄️ About NAT Gateways
A Network Address Translation (NAT) gateway is a networking component in cloud and on-premises environments that enables resources within a private subnet (such as virtual machines or containers) to connect to the internet or other external networks, without exposing these resources directly to incoming connections from those external networks. This helps in enhancing security in cloud infrastructure by keeping resources in private subnets isolated from direct public access.
📄️ Managing NAT Gateways
To manage a NAT gateway, follow these steps:
📄️ Port Forwarding for Instance via VNF
This section outlines the steps to configure port forwarding for an instance using a Virtual Network Function (VNF) in a cloud environment. Port forwarding allows external clients to securely access services (for example SSH, HTTP) hosted on the instance by mapping ports from the VNF’s public IP to the instance’s private IP. This approach improves network segmentation and control by routing all incoming traffic through the VNF layer.
📄️ Port Forwarding with Public IP
In Ananta cloud platform, an additional Public IP enables you to expose internal services hosted on instance to the internet by creating dedicated port forwarding rules. This approach is especially useful when multiple external IPs are needed for services such as SSH, HTTP, or custom applications. By assigning specific public IPs to particular services or instances, you can achieve greater control, flexibility, and network segmentation.
