    Configure the Nuage Networks Remote Network

    Configure the remote network between the Nuage Networks SD-WAN and Prisma Access by completing the following workflows:

    Set up the Remote Network Tunnel in Prisma Access

    Complete the following task to configure the remote network connection as a site-to-site IPSec tunnel.
    1. Select
      Network
      Network Profiles
      IKE Crypto
      Add
       and
      Add
       an IKE crypto profile for the IPSec tunnel.
      Make sure you have specified the
      Template
       of
      Remote_Network_Template
       before starting this task.
    2. Give the profile a name and specify IKE settings.
      Make a note of these settings; you specify the same settings when you create the IPSec tunnel in the Nuage Networks SD-WAN.
    3. Select
      Network
      Network Profiles
      IPSec Crypto
      Add
       and
      Add
       a new IPSec crypto profile.
    4. Specify a name for the profile and specify IPSec crypto parameters.
      Make a note of these parameters; you specify these same parameters when you configure the Nuage Networks side of the remote network tunnel in a later task.
    5. Select
      Network
      Network Profiles
      IKE Gateways
       and
      Add
       a new IKE gateway.
    6. Specify a
      Name
      ,
      Version
      ,
      Peer IP Address Type
      , and
      Authentication
      , and specify a
      Peer Identification
       that will be synchronized with the Nuage Networks configuration.
      Make note of the of the
      User FQDN (email address)
       that you use for the
      Peer Identification
       and the
      Pre-Shared key
       you use; you must match these settings for the Nuage Networks side of the connection in 6 when you Set Up the Remote Network Tunnel in Nuage Networks.
    7. Click the
      Advanced Options
       tab and make sure that
      Enable Passive Mode
       and
      Enable NAT Traversal
       are selected.
      The Nuage Network Services Gateway (NSG) initiates the IKE negotiation, and allows the negotiation to occur even if Nuage Networks side is behind NAT.
    8. Select
      Network
      IPSec Tunnels
       and
      Add
       an IPSec tunnel.
    9. Select the
      IKE Gateway
       and
      IPSec Crypto Profile
       you created earlier in this task.
    10. Select the
      Proxy IDs
       tab and create a default route for all local and remote prefixes.
      Creating this route ensures that all prefixes in the VPN use this IPSec tunnel.
      1. Select
        Panorama
        Cloud Services
        Configuration
        Remote Networks
         and
        Add
         the connection.
      2. Enter a
        Name
        , select the
        Bandwidth
         and
        Region
        , and select the
        IPSec Tunnel
         you specified in a previous step, and specify a route to the Nuage Networks SD-WAN.
        You cannot change the name of this tunnel after you create it.
        This example specifies a
        Static Route
         to the Nuage Networks SD-WAN with an IP address of 10.61.0.0/16.
    12. Commit the configuration changes to Panorama and push the configuration out to Prisma Access for remote networks.
      1. Click
        Commit
        Commit to Panorama
        .
      2. Click
        Commit
        Commit and Push
        . Click
        Edit Selections
        Prisma Access
        , and select both Prisma Access for remote networks and Prisma Access for service setup to push the configuration out to the service.
      3. Click
        OK
        , then click
        Commit and Push
        .
        Prisma Access displays a success page after the commit succeeds.
    13. Make a note of the
      Service IP address
       of the Prisma Access side of the tunnel. To find this address in Panorama, select
      Panorama
      Cloud Services
      Status
      Network Details
      , click the
      Remote Networks
       radio button, and find the address in the
      Service IP Address
       field.

    Set Up the Remote Network Tunnel in Nuage Networks

    After you configure the remote network tunnel in Prisma Access, configure the tunnel in Nuage Networks by completing the following task.
    Note that Dead Peer Detection (DPD) is only configured in Nuage Networks. No DPD configuration is required in Prisma Access because the NSG is the DPD initiator and Prisma Access can only reply to requests.
    1. In your organization, create the Gateway using the Nuage Networks IKE gateway object.
      In the
      IP Address
       field, enter the
      Service IP address
       that you retrieved after you completed the setup of the remote network tunnel in Prisma Access (Step 13.
    2. Define the remote subnet for which traffic will be sent to the gateway.
      The IKE gateway connection uses the underlay breakout mechanism as shown in the following diagram:
      All traffic to Prisma Access is through the underlay. If you enable underlay, and if the remote subnet associated with Prisma Access matches the destination IP in the customer packet, then the Nuage Networks SD-WAN sends the packet to Prisma Access. If the destination IP does not match, the SD-WAN sends the packet to internet breakout using underlay breakout and port address translation (PAT) rules.
    3. Specify a default route to the gateway so that the network sends all internet traffic to Prisma Access.
    4. Create an IKE encryption profile.
      This profile must match the values that you specified in the Prisma Access IPSec configuration.
    5. Create an IKE gateway profile.
      1. Enter a
        Name
         for the gateway profile.
      2. Select
        Check anti-replay
        .
      3. Select the
        Service class
        .
      4. Select the
        Gateway
         and
        Encryption Profile
        , using the settings you created for Prisma Access.
      The example in the following screenshot uses one pre-shared key per connection, which means that the IKE Gateway profile won't use a pre-shared key object, and the
      Authentication Method
       field is empty.
    6. Associate the remote network connection with the NSG uplink port.
      You associate the remote network connection with the Nuage Networks NSG at the uplink VLAN level. This association contains an NSG identifier in RFC 822 format and includes the pre-shared key that is used for the connection.
    7. Check the status of the tunnel connection by entering the following command.
      A status of
      UP
       indicates that the connection is successful. 
      A:vsc1# tools vswitch 86.229.176.112 command "nuage-nsg-ike-cli show tunnel-status-summary"
