Configure automatic tunnel between Secure Access and Firewall Threat Defense devices using SASE wizard

Step 1

Choose Secure Connections > Site-to-Site VPN & SD-WAN , and click Add .

Step 2

In the Topology Name field, enter a name for the SASE topology.

Step 3

Click the SASE Topology radio button and click Create .

Step 4

Configure a Secure Access region by choosing a region from the Region drop-down list:

Step 5

Configure Firewall Threat Defense nodes:

1. Click Add and configure the parameters in the Add Threat Defense Node dialog box.

2. From the Device drop-down list, choose a Firewall Threat Defense device.

   Note	Only Firewall Threat Defense devices managed by Cloud-Delivered Firewall Management Center are displayed in this list. Extranet devices won't appear in the list.

3. From the VPN Interface drop-down list, choose a WAN-facing or internet-facing physical interface that establishes a VPN connection with Secure Access .

Step 6

Configure Tunnel ID and passphrase .

1. In the Prefix for tunnel ID field, enter a prefix containing 8 to 30 characters. The prefix can contain alphabets, numbers, period (.), underscore (_), and dash (-).

   Secure Access uses this prefix to generate the complete tunnel ID after the Cloud-Delivered Firewall Management Center deploys the tunnel in Secure Access . The tunnel ID format is < prefix >@< org >< hub >.sse.cisco.com.

2. The passphrase is auto generated. However, you can regenerate or enter a different passphrase. In the Passphrase field, enter a passphrase containing 16 to 64 characters. The passphrase must contain at least one upper-case alphabet, one lower-case alphabet, and one number, and cannot include special characters.

3. Confirm the passphrase.

4. Click Next .

Step 7

Configure NAT or routing :

1. Check the Enable NAT/outbound only check box to enable Network Address Translation (NAT) for correct routing and identification.

   Use this option if the IP address of the subnet behind this tunnel group overlaps with the IP address in your network. When this option is selected, the tunnel group supports only outbound traffic and cannot provide access to private applications hosted at this site.

   Note	Routing options are unavailable when the network contains overlapping subnets.

2. Configure one of these options for Routing :

   • Click the Static routing radio button.

     Use the Network IP addresses field to add the IP addresses of networks for this tunnel group. Add all the public and private addresses used internally by your organization.

   • Click the Dynamic routing radio button.

     Use this option to advertise your internal networks over BGP.

     In the AS number field, enter the AS number of the device. This value must match the device's BGP AS number in the routing settings of the device.

3. Click Next .

Step 8

Check the Deploy to Threat Defense devices check box to trigger deployment of all the configurations besides the Secure Access auto tunnel configurations that are yet to be deployed on the device.

Step 9

Click Finish to save and validate the configurations, and create the SASE topology.
