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 users connect. After a user connects and authenticates to the portal and gateway, the endpoint establishes a tunnel from its virtual adapter, which has been assigned an IP address from the IP 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 connection traffic as well as the ability to customize security policies for remote users.

Create Interfaces and Zones for GlobalProtect.
Use the
default
virtual router for all interface configurations to avoid having to create inter-zone routing.
Select
Network
Interfaces
Ethernet
. Configure
ethernet1/2
as a Layer 3 Ethernet interface with IP address 203.0.113.1, and then assign it to the
l3-untrust
Security Zone
and the default
Virtual Router
.
Create a DNS “A” record that maps IP address
203.0.113.1
to
gp.acme.com
.
Select
Network
Interfaces
Tunnel
and
Add
the
tunnel.2
interface.
Add
the tunnel interface to a new
Security Zone
called
corp-vpn
, and then assign it to the default
Virtual Router
.
Enable User Identification on the
corp-vpn
zone.
Create security policies to enable traffic flow between the
corp-vpn
zone and the
l3-trust
zone, which enables access to your internal resources.
Select

Policies

Security

, and then

Add

a new rule.

For this example, you would define the rule with the following settings:

Name
(
General
tab)—VPN Access
Source Zone
(
Source
tab)—corp-vpn
Destination Zone
(
Destination
tab)—l3-trust
Use one of the following methods to obtain a server certificate for the interface hosting the GlobalProtect portal and gateway:
(
Recommended
)Import a Server Certificate from a Well-known, Third-party CA
Use Root CA on the Portal to Generate a Self-signed Server Certificate
Select
Device
Certificate Management
Certificates
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 users to connect to the portal without receiving certificate errors, use a server certificate from a public CA.
Create a server profile.
The server profile instructs the firewall on how to connect to the authentication service. Local, RADIUS, Kerberos, SAML, and LDAP authentication methods are supported. This example shows an LDAP authentication profile for authenticating users against the Active Directory.
Create the server profile for connecting to the LDAP server (
Device
Server Profiles
LDAP
).
(Optional) Create an authentication profile.
Attach the server profile to an authentication profile (
Device
Authentication Profile
).
