​
Overview

When you create a resource in Pangolin, you define different targets that specify where traffic should be routed within your network. Each target represents a specific destination that the resource can proxy to when handling incoming requests.
Targets are created on the Newt tunnel, enabling traffic to reach destinations on the remote network without requiring additional routing configuration.

​
How Targets Work

​
Target Routing

Targets function as destination endpoints for your resources:
  1. Resource Creation: When you create a resource, you configure one or more targets
  2. Traffic Routing: Incoming traffic is routed to the appropriate target based on your configuration
  3. Network Access: Newt proxy routes traffic to the local network through the tunnel
  4. Direct Connection: No additional routing is necessary on the remote network

​
Multi-Site Targets (v1.9.0+)

With the introduction of update 1.9.0, targets now have sites associated with them. This enhancement provides significant benefits for reliability and load distribution.

​
Site-Distributed Resources

You can now configure targets across different sites for the same resource:

High Availability

Distribute your resources across multiple sites so that if one site goes down, traffic automatically continues to be served from other available sites.

Load Balancing

Set up load balancing across sites to distribute traffic in a round-robin fashion between all available targets.

​
Load Balancing Requirements

Load balancing between different targets only works when sites are connected to the same node. In managed Pangolin instances with multiple nodes, ensure load balancing occurs on the same node.
To ensure effective load balancing in multi-node environments: 
newt --prefer-endpoint <specific-endpoint> <other-args>
Pangolin currently does not load balance between nodes, only between targets on the same node.

​
Configuring Targets

1

Navigate to Resources

In the Pangolin dashboard, go to the Resources section.
2

Create or Edit Resource

Either create a new resource or select an existing resource to edit.
3

Add Target

Click Add Target to configure a new destination.
4

Configure Target Details

Specify the target configuration:
  • Address: IP address or hostname of the target service
  • Port: Port number where the service is listening
  • Site: Select the site where this target is located
Pangolin uses round-robin load balancing by default, distributing traffic evenly across all targets.
