Create Interfaces and Zones for the LSVPN

1. Configure a Layer 3 interface.

   The portal and each gateway and satellite all require a Layer 3 interface to enable traffic to be routed between sites.

   If the gateway and portal are on the same firewall, you can use a single interface for both components.

   1. Select NetworkInterfacesEthernet and then select the interface you want to configure for GlobalProtect LSVPN.
   2. Select Layer3 from the Interface Type drop-down.
   3. On the Config tab, select the Security Zone to which the interface belongs:

      • The interface must be accessible from a zone outside of your trust network. Consider creating a dedicated VPN zone for visibility and control over your VPN traffic.
      • If you have not yet created the zone, select New Zone from the Security Zone drop-down, define a Name for the new zone and then click OK.
   4. Select the Virtual Router to use.
   5. Assign an IP address to the interface:

      • For an IPv4 address, select IPv4 and Add the IP address and network mask to assign to the interface, for example 203.0.11.100/24.
      • For an IPv6 address, select IPv6, Enable IPv6 on the interface, and Add the IP address and network mask to assign to the interface, for example 2001:1890:12f2:11::10.1.8.160/80.
   6. To save the interface configuration, click OK.
2. On the firewall(s) hosting GlobalProtect gateway(s), configure the logical tunnel interface that will terminate VPN tunnels established by the GlobalProtect satellites.

   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.

   Make sure to enable User-ID in the zone where the VPN tunnels terminate.

   1. Select NetworkInterfacesTunnel and click Add.
   2. In the Interface Name field, specify a numeric suffix, such as .2.
   3. On the Config tab, expand the Security Zone drop-down to define the zone as follows:

      • To use your trust zone as the termination point for the tunnel, select the zone from the drop-down.
      • (Recommended) To create a separate zone for VPN tunnel termination, click New Zone. In the Zone dialog, define a Name for new zone (for example lsvpn-tun), select the Enable User Identification check box, and then click OK.
   4. Select the Virtual Router.
   5. (Optional) To assign an IP address to the tunnel interface:

      • For an IPv4 address, select IPv4 and Add the IP address and network mask to assign to the interface, for example 203.0.11.100/24.
      • For an IPv6 address, select IPv6, Enable IPv6 on the interface, and Add the IP address and network mask to assign to the interface, for example 2001:1890:12f2:11::10.1.8.160/80.
   6. To save the interface configuration, click OK.
3. If you created a separate zone for tunnel termination of VPN connections, create a security policy to enable traffic flow between the VPN zone and your trust zone.

   For example, a policy rule enables traffic between the lsvpn-tun zone and the L3-Trust zone.
