To participate in the LSVPN, the satellites require a minimal amount of configuration. Because the required configuration is minimal, you can pre-configure the satellites before shipping them to your branch offices for installation.
Prepare the Satellite to Join the GlobalProtect LSVPN
Configure a Layer 3 interface. This is the physical interface the satellite will use to connect to the portal and the gateway. This interface must be in a zone that allows access outside of the local trust network. As a best practice, create a dedicated zone for VPN connections for visibility and control over traffic destined for the corporate gateways.
Configure the logical tunnel interface for the tunnel to use to establish VPN tunnels with the GlobalProtect gateways. IP addresses are not required on the tunnel interface unless you plan to use dynamic routing. However, assigning an IP address to the tunnel interface can be useful for troubleshooting connectivity issues. Select Network > Interfaces > Tunnel and click Add. In the Interface Name field, specify a numeric suffix, such as .2. On the Config tab, expand the Security Zone drop-down and select an existing zone or create a separate zone for VPN tunnel traffic by clicking New Zone and defining a Name for new zone (for example lsvpnsat). In the Virtual Router drop-down, select default. (Optional) If you want to assign an IP address to the tunnel interface, select the IPv4 tab, click Add in the IP section, and enter the IP address and network mask to assign to the interface, for example To save the interface configuration, click OK.
If you generated the portal server certificate using a Root CA that is not trusted by the satellites (for example, if you used self-signed certificates), import the root CA certificate used to issue the portal server certificate. The root CA certificate is required to enable the satellite to establish the initial connection with the portal to obtain the LSVPN configuration. Download the CA certificate that was used to generate the portal server certificates. If you are using self-signed certificates, export the root CA certificate from the portal as follows: Select Device > Certificate Management > Certificates > Device Certificates. Select the CA certificate, and click Export. Select Base64 Encoded Certificate (PEM) from the File Format drop-down and click OK to download the certificate. (You do not need to export the private key.) Import the root CA certificate you just exported onto each satellite as follows. Select Device > Certificate Management > Certificates > Device Certificates and click Import. Enter a Certificate Name that identifies the certificate as your client CA certificate. Browse to the Certificate File you downloaded from the CA. Select Base64 Encoded Certificate (PEM) as the File Format and then click OK. Select the certificate you just imported on the Device Certificates tab to open it. Select Trusted Root CA and then click OK.
Configure the IPSec tunnel configuration. Select Network > IPSec Tunnels and click Add. On the General tab, enter a descriptive Name for the IPSec configuration. Select the Tunnel Interface you created for the satellite. Select GlobalProtect Satellite as the Type. Enter the IP address or FQDN of the portal as the Portal Address. Select the Layer 3 Interface you configured for the satellite. Select the Local IP Address to use on the selected interface.
( Optional ) Configure the satellite to publish local routes to the gateway. Pushing routes to the gateway enables traffic to the subnets local to the satellite via the gateway. However, you must also configure the gateway to accept the routes as detailed in Configure the Gateway. To enable the satellite to push routes to the gateway, on the Advanced tab select Publish all static and connected routes to Gateway. If you select this check box, the firewall will forward all static and connected routes from the satellite to the gateway. However, to prevent the creation of routing loops, the firewall will apply some route filters, such as the following: Default routes Routes within a virtual router other than the virtual router associated with the tunnel interface Routes using the tunnel interface Routes using the physical interface associated with the tunnel interface (Optional) If you only want to push routes for specific subnets rather than all routes, click Add in the Subnet section and specify which subnet routes to publish.
Save the satellite configuration. Click OK to save the IPSec tunnel settings. Click Commit.
If required, provide the credentials to allow the satellite to authenticate to the portal. This step is only required if the portal was unable to find a serial number match in its configuration or if the serial number didn’t work. In this case, the satellite will not be able to establish the tunnel with the gateway(s). Select Network > IPSec Tunnels and click the Gateway Info link in the Status column of the tunnel configuration you created for the LSVPN. Click the enter credentials link in the Portal Status field and username and password required to authenticate the satellite to the portal. After the portal successfully authenticates to the portal, it will receive its signed certificate and configuration, which it will use to connect to the gateway(s). You should see the tunnel establish and the Status change to Active.
