How to Apply Traffic Shaping to a VPN Tunnel

  • Last updated on

If you want to configure Quality of Service for a virtual interface as in this example, a VPN tunnel, adapt the traffic shaping configuration.

Assign a QoS Profile to a VPN Tunnel 

  1. Create a TINA VPN Tunnel.
  2. Configure the traffic shaping settings.
  3. Go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > VPN-Service > Site to Site.
  4. Open the TINA Tunnel configuration window.
  5. Click the TI - Bandwidth Protection tab.
  6. From the Bandwidth Policy list, select Assign QoS Profile
  7. From the Assigned QoS Profile list, select your QoS profile.
  8. In the Estimated Bandwidth field, enter the maximum rate for outbound traffic in KB/s. If you enter 0, no shaping occurs.
  9. In the Reverse field, enter the maximum rate of inbound traffic in KB/s. If you enter -1, the same maximum rate is used for outbound and inbound traffic.
  10. Click OK.
  11. Click Send Changes and Activate.
  12. Create the firewall rules for the VPN tunnel traffic. For more information, see How to Create Access Rules for Site-to-Site VPN Access.
