Remote Access VPN (Authentication Profile)
In the GlobalProtect VPN for Remote Access, the GlobalProtect portal and gateway are configured on ethernet1/2, so this is the physical interface where GlobalProtect clients connect. After a client connects and the portal and gateway authenticates it, the client establishes a VPN tunnel from its virtual adapter, which has been assigned an address in the IP address pool associated with the gateway tunnel.2 configuration—10.31.32.3-10.31.32.118 in this example. Because GlobalProtect VPN tunnels terminate in a separate corp-vpn zone, you have visibility into the VPN traffic as well as the ability to customize security policy for remote users.
The following procedure provides the configuration steps for this example. You can also watch the video.
Interfaces and Zones for GlobalProtect.Use the default virtual router for all interface configurations to avoid having to create inter-zone routing.
- Select NetworkInterfacesEthernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 203.0.113.1 and assign it to the l3-untrust zone and the default virtual router.
- Create a DNS “A” record that maps IP address 203.0.113.1 to gp.acme.com.
- Select NetworkInterfacesTunnel and add the tunnel.2 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router.
- Enable User Identification on the corp-vpn zone.
- Create security policy to enable traffic flow between
the corp-vpn zone and the l3-trust zone to enable access to your
- Select PoliciesSecurity and then Add a new rule.
- For this example, you would define the rule with the
- Name—VPN Access
- Source Zone—corp-vpn
- Destination Zone—l3-trust
- Obtain a server certificate for the interface hosting
the GlobalProtect portal and gateway using one of the following
methods:Select DeviceCertificate ManagementCertificates to manage certificates as follows:
- Obtain a server certificate. Because the portal and gateway are on the same interface, the same server certificate can be used for both components.
- The CN of the certificate must match the FQDN, gp.acme.com.
- To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA.
a server profile.The server profile instructs the firewall how to connect to the authentication service. Supported methods are Local, RADIUS, Kerberos, SAML, and LDAP authentication. This example shows an LDAP authentication profile for authenticating users against the Active Directory.Create the server profile for connecting to the LDAP server (DeviceServer ProfilesLDAP).
Create an authentication profile.Attach the server profile to an authentication profile (DeviceAuthentication Profile).
a GlobalProtect Gateway.Select NetworkGlobalProtectGateways and add the following configuration:Interface—ethernet1/2IP Address—203.0.113.1Server Certificate—GP-server-cert.pem issued by GoDaddyAuthentication Profile—Corp-LDAPTunnel Interface—tunnel.2IP Pool—10.31.32.3 - 10.31.32.118
- Configure the GlobalProtect
Portals.Select NetworkGlobalProtectPortals and add the following configuration:
Up Access to the GlobalProtect Portal. This example uses
the following settings:Interface—ethernet1/2IP Address—203.0.113.1Server Certificate—GP-server-cert.pem issued by GoDaddyAuthentication Profile—Corp-LDAP
the GlobalProtect Client Authentication Configurations using
the following settings:Connect Method—On-demand (Manual user initiated connection)External Gateway Address—gp.acme.com
- Set Up Access to the GlobalProtect Portal. This example uses the following settings:
the GlobalProtect Agent Software.Select DeviceGlobalProtect Client.In this example, use the procedure to Host Agent Updates on the Portal.
- (Optional) Enable use of the GlobalProtect mobile
app.Purchase and install a GlobalProtect subscription (DeviceLicenses) to enable use of the app.
- Save the GlobalProtect configuration.Click Commit.
