Netskope IPSec with Versa Director

This guide explains the network and system configuration for the Versa Operating System (VOS) using Versa Director and the Netskope Security Cloud Platform using Secure Web Gateway (NG-SWG).

This document is for experienced network and system administrators who are responsible for configuring and managing public and private cloud infrastructure. It is presumed that admins are aware of virtualization concepts, technologies, and setup of network devices.

Supported Software Versions
  • Versa Director: 20.2.1

  • Versa Analytics: 20.2.1

  • Versa VOS: 20.2.1

  • Netskope R73+

Description

Versa SD-WAN Implementation where internet traffic needs to be sent to Netskope’s Next Generation Secure Web Gateway, this guide captures the configuration of the Versa Operating System (VOS) using Versa Director (Orchestrator), and the required Netskope configurations.

Netskope interoperability with Versa branches can be achieved using Site-to-Site IPSec VPN or GRE from the Versa WAN-Edge device to a Netskope Next Generation Secure Web Gateway (NG-SWG) based on parameters provided by Netskope.  

Netskope and Versa support both IKEv2/IPSec and GRE-based tunnels.

    image14.tiff
  9. In Policy Configuration, click image9.tiff to add two new policies:

    1. Add a policy to accept HTTP traffic, and click OK.

      image15.tiff
    2. Add a another policy to accept HTTPS traffic, and click OK.

      image16.tiff
  10. Click OK.

    image17.tiff
  11. Click the green image9.tiff for the tunnel configuration to add the tunnel.

    image18.tif
  12. Configure the Inbound NAT, Services, and Management Servers tabs per your requirements, and clickRecreate to create workflow template.

    Newimage18.tiff
  13. Go to Configuration > Templates > Device Templates, and select the template you created in the previous step to enter the template configuration view.

    image19.tiff
  14. Go to Services > IPSec > VPN Profiles. Because 2 tunnels were selected, two separate VPN profiles have been created: Netskope-gw1 and Netskope gw2.

  15. Click Netskope-gw1 to edit, and click the IKE tab.

  16. Change the DH group to Diffie-Hellman-Group 14 2048.

    image20.tiff
  17. Click the IPSec tab, and change the DH group to Diffie-Hellman-Group 14 2048, and then click OK.

    image21.tiff
  18. Click Netskope-gw2, and modify the Peer IP to that of the backup tunnel endpoint.

    image22.tiff
  19. Click the IKE tab, and change the DH group to Diffie-Hellman-Group 14 2048, and Peer Auth Identity to the backup tunnel endpoint.

    image23.tiff
  20. Click the IPsec tab, and change the DH group to Diffie-Hellman-Group 14 2048, and then click OK.

    image24.tiff
  21. Go to Workflows > Devices > Devices, and click OK to add a device template based on the workflow template created in previous step. Enter the basic information under Basic > Device Service template and tabs.

  22. Click the Tunnel Information tab, and verify that tunnel information is auto-populated. If some information has to be provided by the user, update the information.

    image25.tiff
  23. In the Bind Data section, enter your bind data information, and click OK:

    1. netskope-gw-1_Local_auth_ip_identifier__IKELIdentifier is the Versa source WAN IP for the primary tunnel. Copy the local auth identifier to add it in the Netskope UI.

    2. netskope-gw-1_Local_auth_key__IKELKey is the pre-shared key for the primary tunnel. Copy the auth key to add it in the Netskope UI.

    3. netskope-gw-2_Local_auth_ip_identifier__IKELIdentifier is the Versa source WAN IP for backup tunnel. Copy the local auth identifier to add it in the Netskope UI.

    4. netskope-gw-2_Local_auth_key__IKELKey is the pre-shared key for the backup tunnel. Copy the auth key to add it in the Netskope UI.

    image26.tiff
  24. Deploy the device workflow configuration and onboard the device.

Verification

To create the IPSec tunnels for Versa Director in the Netskope UI:

  1. Go to Settings > Security Cloud Platform > IPSec.

  2. Click Add New Tunnel.

  3. In the Add New IPSec Tunnel window:

    • Tunnel Name: Enter a name for the IPSec tunnel.

    • Source IP Address: (Optional) Enter the source peer IP address (i.e., exit public IP) of the Versa router that Netskope will receive packets from. Netskope identifies traffic belonging to your organization through your router or firewall IP addresses.

    • Source Identity: Enter the local-auth-info id-string from the VOS configuration. The router or firewall uses the source identity for authentication during Internet Key Exchange (IKE).

    • Primary Netskope POP: Select the primary Netskope point of presence (POP) closest to you, and copy the IPSec Gateway IP address. You need this information to establish the primary IPSec tunnel on your Versa router. For optimal performance, Netskope recommends using the geographically closest POPs and configuring at least two tunnels for each egress location in your network.

    • Failover Netskope POP: Select the backup Netskope POP closest to you, and copy the IPSec Gateway IP address. You need this information to establish the backup IPSec tunnel on your Versa router. For optimal performance, Netskope recommends using the geographically closest POPs and configuring at least two tunnels for each egress location in your network.

    • Pre-Shared Key (PSK): Enter the pre-shared key that both sides of the tunnel will use to authenticate one another. The PSK must be unique for each tunnel.

    • Encryption Cipher: Select an encryption algorithm for the IPSec tunnel.

    • Maximum Bandwidth: Enter the maximum bandwidth for the IPSec tunnel. The tunnel size can be up to 1 Gbps. To enable the 1 Gbps option, contact your Sales Representative.

    • Advanced Settings: Click to view the following options.

      • Rekey: Select to rekey SAs when they expire. Netskope recommends using the default setting.

      • Reauthentication: Select to create new IKE and IPSec SAs when they expire. Netskope recommends using the default setting.

    Add-New-IPSec-Tunnel-Window.png
  4. Click Add.

To view the IPSec tunnel information, click the tunnel name. If the IPSec tunnel configuration is successful, the Status will be Netskope-Up-Status-Icon.png Up.
