In this page you find:
This page shows three tabs: Users and Groups allow to manage all the clients that have access to the VPN service, either OpenVPN or IPsec, and Settings, that allows to define different means of authentication, either local on the Endian 4i Edge Appliance or remote.
In this page, all users that have an account on the Endian 4i Edge Appliance‘s VPN server are displayed in the table, and for each the following information is shown.
Name. The name of the user.
Remark. A comment.
Authentication server. The server used for the user authentication, which is either local (the Endian 4i Edge Appliance itself) or LDAP (an external LDAP server, configurable in the Settings tab).
Actions. The available operation that can be carried out on the account.
Note
Editing an LDAP user only allows to modify the local options, not other data like username or password, which are entirely managed by the LDAP server.
Click on Add new local user above the table to add a new local account. In the form that will show up, the following options can be specified for each user.
The login name of the user.
An additional comment.
This checkbox is only visible if at least one external authentication server has been configured. Once it has been selected the following password input fields will disappear and the user will be authenticated by using the external authentication servers.
The password for the user, to be entered twice. The passwords are actually not shown: To see them, tick the two checkboxes on their right.
This field contains the TOTP secret for the specific user. Due to the constraints in creating these secrets it is not possible to insert them manually but they must be generated by clicking on the Generate new secret button. A QR code representation of the secret can be displayed by clicking on the Show QR Code button.
One-Time Passwords
There are many different one-time password algorithms. On Endian 4i Edge Appliance systems the Time-based One-Time Password algorithm has been implemented as described in RFC 6238. Since this is an open standard, applications exist for almost all devices (Android, iOS and Windows smartphones, PCs etc.). To be able to use a device, it needs to be initialized with the One Time Password Secret: Either do this by entering the secret manually or by taking a picture of the QR code.
Select how to assign a certificate to the user. The choices available in the drop-down menu are: Generate a new certificate, Upload a certificate, and Upload a Certificate signing request. Upon selection, below the drop-down menu appear the available options for each mode, which are described in the Certificates page.
The Organisation Unit to which the user belongs to, i.e., the company, enterprise, or institution department identified with the certificate.
The organisation to which the user belongs to.
The city (L in the certificate) in which the organisation is located.
The state or province (ST in the certificate) in which the organisation is located.
The Country (C in the certificate) in which the organisation is located, chosen from those in the selection menu. By typing one or more letters, matching countries are searched for and displayed.
The e-mail address of the user.
In this part of the panel it is possible to assign membership to one or more groups to the user. In the search widget it is possible to filter existing groups to find matching groups. Group membership is added by clicking on the + on the right of the group name. Groups to which the user belongs are show in the textfield below. There are also shortcuts to Add all and to Remove all groups memberships at once.
Tick this checkbox to allow the OpenVPN protocol to be used. This option will reveal a box in which to specify custom option for the account, see below.
Tick this checkbox to show a box in which to choose the L2TP tunnel to be used.
Hint
The box for L2TP options will appear below the OpenVPN options box, if also OpenVPN option are to be overridden
By default, a user can use all services, i.e., OpenVPN, IPsec XAuth, and L2TP. For any new authentication sever defined, new checkboxes will appear. Tick any checkboxes to enable or disable the service for the user.
Changed in version 5.1.
Tick the checkbox to allow the user to connect to the Endian 4i Edge Appliance using the selected services.
If this option is checked, all the traffic from the connecting client, regardless of the destination, is routed through the uplink of the Endian 4i Edge Appliance. The default is to route through the VPN only the client traffic to the internal networks (see next options).
For advanced users only. Normally, when a client connects, tunnelled routes to networks that are accessible via VPN are added to the client’s routing table, to allow it to connect to the various local networks reachable from the Endian 4i Edge Appliance. This option should be enabled if this behaviour is not wanted, but the client’s routing tables (especially those for the internal zones) should be modified manually.
When this option is active, the client will have access to the GREEN, BLUE, or ORANGE zone. These options have no effect if the corresponding zones are not enabled.
If any networks is written here (one per line and in CIDR notation, only routes to these networks will be sent to the client.
When the user will be used to connect a remote gateway in a GW2GW setup, this box contains the list of the networks laying behind the client that must be made reachable from the other clients through the OpenVPN Server. It is not used for roadwarrior (single) user.
Warning
This option is mandatory if the user will be used to connect a GW2GW client. If no networks are specified here, no route to them will be pushed to the other clients, making them unreachable.
Dynamic IP addresses are assigned by default to clients, but a static IP address provided here will be assigned to the client whenever it connects.
Note
If the client connects to a multicore VPN server running on the Endian 4i Edge Appliance, this assignment will not be taken into account.
Assign custom nameservers on a per-client basis here. This setting (and the next one) can be defined, but enabled or disabled at will.
Assign custom search domains on a per-client basis here.
Note
When planning to have two or more branch offices connected
through a Gateway-to-Gateway VPN, it is good practice to choose
different subnets for the LANs in the different branches. For
example, one branch might have a GREEN zone with the
192.168.1.0/24 subnet while the other branch uses
192.168.2.0/24. Using this solution, several possible sources
for errors and conflicts will be avoided. Indeed, several
advantages come for free, including: The automatic assignment of
correct routes, without the need for pushing custom routes, no
warning messages about possibly conflicting routes, correct local
name resolution, and easier WAN network setup.
This drop-down menu allows to choose the tunnel that will be employed by the user, among those already defined.
Note
If no IPsec tunnel has yet been configured or all IPsec tunnels are in closed state, the Select a tunnel… message appears instead of the list of IPsec tunnels.
In this page a table is displayed, which shows all the groups that are either defined on the Endian 4i Edge Appliance or on an external LDAP server. For each group the following information is shown:
Groupname. The name of the group.
Remark. A comment.
Authentication server. The server used for the user authentication, which is either local (the Endian 4i Edge Appliance itself) or LDAP (an external LDAP server, configurable in the Settings tab).
Actions. The available operation that can be carried out on the group.
Click on Add new local group above the table to add a new local group. In the form that will show up, the following options can be specified for each group.
The name given to the group.
A comment.
In this part of the panel it is possible to assign users to the group. in the search widget it is possible to filter existing local users to find matching users. Users are added to the group by clicking on the + on the right of the username. Users in the Group are shown in the textfield below. There are also shortcuts to Add all and to Remove all users to/from a group.
Tick this checkbox to allow the OpenVPN protocol to be used. This option will reveal a box in which to specify custom option for the account, which are the same as those specified for the local users.
Tick this checkbox to show a box in which to choose the L2TP tunnel to be used from a drop-down menu.
Note
If no IPsec tunnel has yet been configured or all IPsec tunnels are in closed state, the Select a tunnel… message appears instead of the list of IPsec tunnels.
Hint
The box for L2TP options will appear below the OpenVPN options box, if also OpenVPN option are to be overridden
Tick the checkbox to enable the user, i.e., to allow her to connect to the OpenVPN server on the Endian 4i Edge Appliance.
Warning
While the same user can be legally part of one or more groups, care must be taken that the groups the user belongs to do not define contrasting override options. As an example, consider a user member of two groups, one allowing access only to the GREEN zone, and one only to the BLUE. In this case, it is not easy to predict whether that user will be granted or not access to the BLUE or GREEN zone. The management of these issues is left to the manager of the OpenVPN server.
This page contains the current configuration of the authentication servers on which the Endian 4i Edge Appliance relies and allows for their management. Several authentication servers are available: LDAP/Active directory, Local, One Time Password, Radius and Split Data.
There are two tables in this page, one displaying information about Authentication servers, and one showing the Authentication server mappings. In the former, this information is shown:
Name. The name given to the server
Type. Whether the server is a local or an external LDAP one.
Service. Which authentication is available for that server.
Actions.The available operation that can be carried out on the server.
The table at the bottom shows which authentication server is used in each available service, namely IPsec XAuth, OpenVPN or L2TP.
The only available action for each mapping is to edit it. By clicking on
the 
icon, a form will appear, in which a selector allows to
select which authentication backends will be used for that service.
Hint
It is possible to map multiple servers to a service and use the same authentication server for more services.
A click on the Add new authentication server link above the tables opens a form in which to supply all data to set up a new authentication server.
The name given to the authentication server.
Tick the checkbox to enable the server.
Select the server type from the drop-down menu. The following options are available:
LDAP / Active Directory
Choose this option to use an LDAP server to authenticate the users. The following options are supported for this type:
The URI of the LDAP server.
This drop-down menu allows the choice of the type of the authentication server among Generic, Active Directory, Novell eDirectory, or OpenLDAP. Depending on this selection, some options will not be displayed.
The fully distinguished name of the LDAP account that is used to retrieve user data from the LDAP server.
The password of the bind DN user.
The following options depend on the server setup and are used to select users and groups on the server : LDAP user base DN, LDAP group base DN.
When using a Generic LDAP server type additional parameters must be configured: LDAP user search filter, LDAP user unique ID attribute, LDAP group unique ID attribute, LDAP group member attribute, LDAP group search filter.
Limit to specified groups This option allows to select which groups on the LDAP server are allowed to connect to the Endian 4i Edge Appliance‘s OpenVPN server.
Local
Choose this option to create and manage users locally. The following option is available:
This option allows to select which groups on the LDAP server are allowed to connect to the Endian 4i Edge Appliance‘s OpenVPN server.
RADIUS
Choose this option to configure a RADIUS server. Note that RADIUS servers can only be used as password providers in both One Time Password and Split Data authentication servers. To use a RADIUS server the following options must be defined:
The address of the RADIUS server.
The shared secret between the RADIUS server and the Endian 4i Edge Appliance.
The TCP port that is used for the RADIUS authentication.
The TCP port that is used for the accounting.
The Endian 4i Edge Appliance‘s RADIUS identifier or NAS ID.
Split Data (User Information & Password)
This server type works as a proxy for two different providers, but it does not add two-factor authentication. By choosing this server, two drop-down menus allow to chose different providers for users and passwords:
Choose from the drop-down menu which authentication server will be used to retrieve the user information.
Choose from the drop-down menu which authentication server will be used to retrieve the user information.
Note
If any servers of type One Time Password or type RADIUS have been defined, they will available for selection as password provider.
One Time Password
The choice of this option enables two-factor authentication. Like the Split Data option, this server type acts as a proxy for two different providers with the addition of the the two-factors authentication using a time-based, one-time passwords. Choosing this type will let you select the sources for both the user information as well as the password providers. the options are the same as in the Split Data option:
Choose from this drop-down menu the authentication server from which to retrieve the user information.
Choose from this drop-down menu the authentication server used to authenticate the users.
