Traffic Management

SecureLink V2 provides comprehensive traffic management capabilities to control bandwidth usage, prioritize critical applications, and enforce security boundaries.

Concepts​

Traffic Profiles​

Traffic Profiles define bandwidth limits for upload and download speeds. These profiles are reusable and can be applied to multiple traffic limiters.

  • Upload Rate: Maximum upload speed (in Mbps) or Unlimited.
  • Download Rate: Maximum download speed (in Mbps) or Unlimited.

Traffic Limiters (QoS)​

Traffic Limiters apply Traffic Profiles to specific traffic flows based on destination or application. They allows you to guarantee quality of service for business-critical applications while throttling recreational traffic.

  • Priority: High, Medium, or Low.
  • Scope: Can be applied globally or to specific Device Groups / Clients.
  • Matching Criteria:
    • Destination: IP address, subnet, or domain.
    • Application: Application signature (e.g., "Office365", "YouTube").

Trust Policies (Firewall)​

Trust Policies act as an internal firewall, controlling which devices can communicate with specific destinations or applications.

  • Action: Permit or Deny.
  • Source: Device Group or specific Client.
  • Destination: IP address, subnet, or domain.
  • Reflexive: Automatically allow return traffic (stateful).

Configuring Traffic Management​

Creating a Traffic Profile​

  1. Navigate to Network > Traffic Management.
  2. Click Add Profile.
  3. Enter a Name and Description.
  4. Set the Upload and Download limits (set to 0 for unlimited, or check the Unlimited box).
  5. Click Save.

Creating a Traffic Limiter​

Note: Traffic Limiters are currently managed via the API or individual Device/Group detail pages.

  1. Go to Equipment > Devices or Device Groups.
  2. Select a device or group.
  3. Navigate to the Traffic Limiters tab.
  4. Click Add Limiter.
  5. Select a Traffic Profile.
  6. Define the Destination and/or Application.
  7. Set the Priority.
  8. Click Save.

Creating a Trust Policy​

Note: Trust Policies are managed via the Device Groups page.

  1. Go to Equipment > Device Groups.
  2. Select a group.
  3. Navigate to the Trust Policies tab.
  4. Click Add Policy.
  5. Choose Permit or Deny.
  6. Define the Destination and Application.
  7. Click Save.

Monitoring​

You can monitor the effectiveness of your policies in the Monitoring > Traffic section.

  • Real-time charts show bandwidth usage per class (High/Medium/Low).
  • Dropped packets counters help identify if limits are too aggressive.
