Network ports in xneelo Cloud

A network port is a virtual connection that links a device to a network. Each port is assigned a fixed IP address from the subnet it belongs to.

Ports are created automatically when you attach an interface to an instance or router. You can also create ports directly and attach them later.

Security groups can be applied to individual ports to control inbound and outbound traffic. Applying security groups at the port level (rather than on the instance) gives you more granular control over network access.

Ports are useful when you need to:

• Attach a specific IP address to an instance.
• Pre-provision network connectivity before creating an instance.
• Control network traffic by applying security groups at the port level.
• Connect routers and subnets within your project.

You can view all ports for a network in the Cloud dashboard.

You’ll see details such as port name, fixed IP(s), and you can edit port settings and security groups.
