Add an SD-WAN Device

1. Log in to the Panorama Web Interface.
2. Select PanoramaSD-WANDevices and Add a new SD-WAN firewall.
3. Select the managed firewall Name to add as an SD-WAN device. You must add your SD-WAN firewalls as managed devices before you can add them as an SD-WAN device.
4. Select the Type of SD-WAN device.

   • Hub—A centralized firewall deployed at a primary office or location to which all branch devices connect using a VPN connection. Traffic between branches passes through the hub before continuing to the target branch, and connects branches to centralized resources at the hub location. The hub device processes traffic, enforces policy rules, and manages link swapping at the primary office or location.
   • Branch—A firewall deployed at a physical branch location that connects the hub using a VPN connection and provides security at the branch level. The branch device processes traffic, enforces policy rules, and manages link swapping at the branch location.
5. Select the Virtual Router Name to use for routing between the SD-WAN hub and branches. By default, an sdwan-default virtual router is created and enables Panorama to automatically push router configurations.
6. Enter the SD-WAN Site name to identify the geographical location or purpose of the device.

   The SD-WAN Site name supports all upper-case and lower-case alphanumerical and special characters. Spaces are not supported in the Site name and result in monitoring (PanoramaSD-WANMonitoring) data for that site not to be displayed.

   If you are adding an HA pair, you must use the same Site name for the two peers.
7. (PAN-OS 9.1.3 and later 9.1 releases and SD-WAN Plugin 1.0.3 and later 1.0 releases) If you are adding a hub that is behind a device performing NAT for the hub, you must specify the IP address or FQDN of the public-facing interface on that upstream NAT-performing device, so that Auto VPN Configuration can use that address as the tunnel endpoint of the hub. It is the IP address that the branch office’s IKE and IPSec flows must be able to reach. (You must have already configured a physical Ethernet interface for SD-WAN.)

   1. On the Upstream NAT tab, enable Upstream NAT.
   2. Add an SD-WAN interface; select an interface you already configured for SD-WAN.
   3. Select IP Address or FQDN and enter the IPv4 address without a subnet mask (for example, 192.168.3.4) or the FQDN of the upstream device, respectively.
   4. Click OK.

      You must also set up the inbound Destination NAT with a one-to-one NAT policy, and you must not configure port translation to the IKE or IPSec traffic flows.

      If the IP address on the upstream device changes, you must reconfigure the new IP address and push it out to the VPN cluster members. You must use the CLI commands clear vpn ipsec-sa, clear vpn ike-sa, and clear session all on both the branch and hub. You must also clear session all on the virtual router where you configured the NAT policy for the IP addresses.
8. (Required for pre-existing customers) You must modify your security policy rules by adding the SD-WAN predefined zones to the correct Source and Destination zones.
9. (Optional) Configure Border Gateway Protocol (BGP) routing.

   To automatically set up BGP routing between the VPN cluster members, enter the BGP information below. If you want to manually configure BGP routing on each firewall or use a separate Panorama template to configure BGP routing for more control, leave the BGP information below blank.

   Before implementing SD-WAN with BGP routing in an environment where BGP is already in use, ensure that the BGP configuration generated by the SD-WAN plugin doesn’t conflict with your pre-existing BGP configuration. For example, you must use the existing BGP AS number and router ID values for the corresponding SD-WAN device values. If the BGP configuration generated by the plugin conflicts with your pre-existing BGP configuration, the pre-existing BGP configuration takes precedence. If you want the pushed configuration to take precedence, you must enable the force template value when doing a Panorama push.

   1. Select the BGP tab and enable BGP to configure BGP routing for SD-WAN traffic.
   2. Enter the BGP Router ID, which must be unique among all routers.
   3. Specify a static IPv4 Loopback Address for BGP peering. Auto VPN configuration automatically creates a Loopback interface with the same IPv4 address that you specify. If you specify an existing loopback address, the commit will fail, so you should specify an IPv4 address that is not already a loopback address.
   4. Enter the AS Number. The autonomous system number specifies a commonly defined routing policy to the internet. The AS number must be unique for every hub and branch location.
   5. Enter Prefix(es) to Redistribute. On a hub device, you must enter at least one prefix to redistribute. Branch devices do not have this option; subnets connected to branch locations are redistributed by default.
10. Click OK.
11. (SD-WAN Plugin 1.0.1 and later releases) Select Group HA Peers at the bottom of the screen to display branches (or hubs) that are HA peers together.

12. (PAN-OS 9.1.2 and later 9.1 releases, and SD-WAN Plugin 1.0.2 and later 1.0 releases) Have Panorama create and push to firewalls a Security policy rule that allows BGP to run between branches and hubs.

    1. Select BGP Policy at the bottom of the screen and Add.
    2. Enter a Policy Name for the Security policy rule that Panorama will automatically create.
    3. Select Device Groups to specify the device groups to which Panorama pushes the Security policy rule.
    4. Click OK.

13. Select Push to Devices to push your configuration changes to your managed firewalls.
