What are application tunnels?

Application tunnels provide a secure pathway between your Atlassian cloud organization and Data Center or Server instances that live in your network. This pathway can be used to integrate your products through application links that would otherwise require allowing incoming connections to your network. Thanks to network tunneling, you can integrate your Atlassian products and exchange data and functionalities between them in a secure way, without exposing your network or allowlisting any incoming connections or IPs.

How it works

Here you can see how an application tunnel and links using it integrate your products:

Diagram showing how application tunnels connect your Atlassian cloud and self-managed products.
  1. Tunnel server: You access it from admin.atlassian.com where you create a tunnel.

  2. Tunnel client: Installed as a Marketplace app in your self-managed instance.

  3. Application link (cloud): You create a tunneled application link in each of your cloud products and point it at an existing tunnel. You can link multiple cloud products to a single tunnel. The application link must always be created on the cloud side.

  4. Application link (self-managed): The reciprocal link will be automatically created in your self-managed instance. Only incoming connections to your network use the tunnel, the outgoing ones will reach your cloud products directly.

Supported products

The following products support application tunnels:

Cloud

Security

To learn more about the security, see Application tunnel security.

Limitations

Each self-managed instance can receive only one tunnel from admin.atlassian.com. You can still link multiple cloud products to this tunnel, and you can also create multiple tunnels in cloud going to different self-managed instances. This limitation will affect you if you’d like to link multiple cloud organizations to a single self-managed instance, which isn’t supported.

Available features

When integrating cloud and self-managed products, there will be some differences in feature you might know from your current integrations. For more info on available integrations and feature differences, see Integrate Atlassian cloud and self-managed products.
