SSL VPN with local user password policy

This topic provides a sample configuration of SSL VPN for users with passwords that expire after two days. Users are warned after one day about the password expiring. The password policy can be applied to any local user password. The password policy cannot be applied to a user group or a local remote user such as LDAP/RADIUS/TACACS+.

In FortiOS 6.2, users are warned after one day about the password expiring and have one day to renew it. When the expiration time is reached, the user cannot renew the password and must contact the administrator for assistance.

In FortiOS 6.0/5.6, users are warned after one day about the password expiring and have to renew it. When the expiration time is reached, the user can still renew the password.

SSL VPN with LDAP-integrated certificate authentication

Leave a reply

SSL VPN with LDAP-integrated certificate authentication

This topic provides a sample configuration of SSL VPN that requires users to authenticate using a certificate with LDAP UserPrincipalName checking.

This sample uses Windows 2012R2 Active Directory acting as both the user certificate issuer, the certificate authority, and the LDAP server.

Sample network topology

Sample configuration

In this sample, the UserPrincipal Name is included in the subject name of the issued certificate. This is the user field we use to search LDAP in the connection attempt.

To use the user certificate, you must first install it on the user’s PC. When the user tries to authenticate, the user certificate is checked against the CA certificate to verify that they match.

Every user should have a unique user certificate. This allows you to distinguish each user and revoke a specific user’s certificate, such as if a user no longer has VPN access.

To install the server certificate:

The server certificate is used for encrypting SSL VPN traffic and will be used for authentication.

  1. Go to System > Feature Visibility and ensure Certificates is enabled.
  2. Go to System > Certificates and select Import > Local Certificate.

l Set Type to Certificate. l Choose the Certificate file and the Key file for your certificate, and enter the Password. l If desired, you can change the Certificate Name.

The server certificate now appears in the list of Certificates.

To install the CA certificate:

The CA certificate is the certificate that signed both the server certificate and the user certificate. In this example, it is used to authenticate SSL VPN users.

  1. Go to System > Certificates and select Import > CA Certificate.
  2. Select Local PC and then select the certificate file.

The CA certificate now appears in the list of External CA Certificates. In the example, it is called CA_Cert_1.

To configure SSL VPN using the GUI:

  1. Configure the interface and firewall address.

WAN interface is the interface connected to ISP. This example shows static mode. You can also use DHCP or PPPoE mode. The SSL VPN connection is established over the WAN interface.

Port1 interface connects to the internal network.

  1. Go to Network > Interface and edit the wan1
  2. Set IP/Network Mask to 20.120.123/255.255.255.0.
  3. Edit port1 interface and set IP/Network Mask to 168.1.99/255.255.255.0.
  4. Click OK.
  5. Go to Firewall & Objects > Address and create an address for internet subnet 168.1.0.
  1. Configure the LDAP server.
    1. Go to User& Device > LDAP Servers > Create New. l Specify Name and ServerIP/Name.

l Set Distinguished Name to dc=fortinet-fsso,dc=com. l Set Bind Type to Regular. l Set Username to cn=admin,ou=testing,dc=fortinet-fsso,dc=com. l Set password.

  1. Configure PKI users and a user group.

To use certificate authentication, PKI users must be created in the CLI. Use the CLI console to enter the following commands:

config user peer

edit user1

set ca CA_Cert_1 set ldap-server “ldap-AD” set ldap-mode principal-name

end

Now that you have created a PKI user, a new menu is added to the GUI. a. Go to User& Device > PKI to see the new user.

  1. Go to User& Device > User> UserGroups and create a group sslvpn-group.
  2. Add the PKI peer object you created as a local member of the group.
  3. Add a remote group on the LDAP server and select the group of interest. You need these users to be members using the LDAP browser window.
  1. Configure SSL VPN web portal.
    1. Go to VPN > SSL-VPN Portals to edit the full-access

end

Sample installation

To use the user certificate, you must first install it on the user’s PC. When the user tries to authenticate, the user certificate is checked against the CA certificate to verify that they match.

Every user should have a unique user certificate. This allows you to distinguish each user and revoke a specific user’s certificate, such as if a user no longer has VPN access.

To install the user certificate on Windows 7, 8, and 10:

  1. Double-click the certificate file to open the Import Wizard.
  2. Use the Import Wizard to import the certificate into the Personal store.

To install the user certificate on Mac OS X:

  1. Open the certificate file, to open Keychain Access.
  2. Double-click the certificate.
  3. Expand Trust and select Always Trust.

To see the results of tunnel connection:

SSL VPN multi-realm

This sample recipe shows how to create a multi-realm SSL VPN that provides different portals for different user groups.

Sample network topology

Sample configuration

WAN interface is the interface connected to ISP. This example shows static mode. You can also use DHCP or PPPoE mode. The SSL VPN connection is established over the WAN interface.

To configure SSL VPN using the GUI:

  1. Configure the interface and firewall address. Port1 interface connects to the internal network.
    1. Go to Network > Interface and edit the wan1
    2. Set IP/Network Mask to 20.120.123/255.255.255.0.
    3. Edit port1 interface and set IP/Network Mask to 168.1.99/255.255.255.0. d. Click OK.
    4. Go to Firewall & Objects > Address and create an address for internet QA_subnet with subnet 192.168.1.0/24 and HR_subnet with subnet 10.1.100.0/24.
  2. Configure user and user group.
    1. Go to User& Device > UserDefinition to create local users qa-user1 and hr-user1.
    2. Go to User& Device > UserGroups to create separate user groups for web-only and full-access portals:
      • QA_group with member qa-user1.
      • HR_group with the member hr-user1.
    3. SSL VPN web portal configuration.
      1. Go to VPN > SSL-VPN Portals to create portal qa-tunnel.
      2. Enable tunnel-mode.
      3. Create a portal hr-web with web-mode enabled.
    4. SSL VPN realms configuration.
      1. Go to System > Feature Visibility to enable SSL-VPN Realms.
      2. Go to VPN > SSL-VPN Realms to create realms for qa and hr.
    5. SSL VPN settings configuration.
      1. Go to VPN > SSL-VPN Settings.
      2. Choose proper Listen on Interface, in this example, wan1.
      3. Listen on Port 10443.
      4. Choose a certificate for ServerCertificate. The default is Fortinet_Factory.
      5. Under Authentication/Portal Mapping, set default Portal Web-access for All OtherUsers/Groups.
      6. Create new Authentication/Portal Mapping for group QA_group mapping portal qa-tunnel.
      7. Specify realm with qa.
      8. Add another entry for group HR_group mapping portal hr-web.
      9. Specify realm with hr.
    6. SSL VPN firewall policy configuration.
      1. Go to Policy & Objects > IPv4 Policy.
      2. Create a firewall policy for QA access.
      3. Fill in the firewall policy name. In this example: QA sslvpn tunnel mode access.
      4. Incoming interface must be SSL-VPN tunnel interface(ssl.root).
      5. Choose an Outgoing Interface. In this example: port1.
      6. Set the source to all and group to QA_group.
      7. In this example, the destination is the internal protected subnet QA_subnet.
      8. Set schedule to always, service to ALL, and Action to Accept.
      9. Click OK.
      10. Create a firewall policy for HR access.
      11. Fill in the firewall policy name. In this example: HR sslvpn web mode access.
      12. Incoming interface must be SSL-VPN tunnel interface(ssl.root).
      13. Choose an Outgoing Interface. In this example: port1.
      14. Set the source to all and group to HR_group.
      15. In this example, the destination is the internal protected subnet HR_subnet.
      16. Set schedule to always, service to ALL, and Action to Accept.
      17. Click OK.

To configure SSL VPN using the CLI:

  1. Configure the interface and firewall address.

config system interface edit “wan1” set vdom “root”

set ip 172.20.120.123 255.255.255.0
