Sky Link Input | Description
From Node field | Specifies the node from which you want to link to a private network.
Allow IP Range field | Specifies the IP range that will be allowed in the link. Possible inputs are as follows: 10.2.0.101,10.2.0.102,10.2.0.103 Comma-separated list of single IP addresses 10.2.0.0/16,10.3.0.0/16,10.4.0.0/16 Comma-separated list of masked IP ranges
To Node field | Specifies the node to which you want to link a private network.
Create Link button | Creates a Sky Router link between two {ANYNODE}s, allowing the specified IP range.

Sky Link Routes
While there are numerous possibilities, the two most commonly used Sky Link route models are illustrated below:
Sequential Route (One Way)
This route directs traffic in one direction over one or multiple nodes. The sequential setup is primarily used for private edge and/or hybrid environments.
For example, let's assume we have three nodes:

- Node1 has the private network 10.1.0.0
- Node2 has the private network 10.2.0.0
- Node3 has the private network 10.3.0.0

The routing would be:

- Node1 -> 10.2.0.0/16, 10.3.0.0/16 -> Node2
- Node2 -> 10.3.0.0/16 -> Node3
- Node3 (no route)

As a result, Node1 can access 10.1.0.0, 10.2.0.0, and 10.3.0.0; Node2 can access 10.2.0.0 and 10.3.0.0; and Node3 can only access 10.3.0.0.
Circular Route (Round Trip)
This route connects each node visible to each other. The circular setup is primarily used in distributed computing environments.
For example, let's assume we have three nodes:

- Node1 has the private network 10.1.0.0
- Node2 has the private network 10.2.0.0
- Node3 has the private network 10.3.0.0

The routing would be:

- Node1 -> 10.2.0.0/16, 10.3.0.0/16 -> Node2
- Node2 -> 10.1.0.0/16, 10.3.0.0/16 -> Node3
- Node3 -> 10.2.0.0/16, 10.1.0.0/16 -> Node1

As a result, each node can access 10.1.0.0, 10.2.0.0, and 10.3.0.0.

Sky Link Dialog | Description
| The "Sky Link" dialog allows you to disable, enable, test, and remove a link. To open this dialog, click on the IP address area of the link arrow. Here are the features of the dialog:
Enable Link button | Enables an existing link and activates the network traffic.
Disable Link button | Disables an existing link and deactivates the network traffic.
Test Link button | Tests whether the link is set up and can reach the specified network.
Delete Link button | Removes the Sky Link from the Sky Router.
Close button | Closes the dialog window.

#### The skylink Policy The following is a list of policy grants that define and regulate access permissions for both users and the API. To manage these policies, please use the Roles dialog.
