Group and User Access Policies

This chapter describes how to define users and groups and how to configure SSL VPN Concentrator access policies and bookmarks for the users and groups. This chapter includes the following topics:

• Editing Global Policy Settings

• Adding and Editing Global Policies

• Defining and Editing Global Bookmarkss

• Adding a New Group, Deleting a Group and Editing Group Settings

• Defining and Editing Group Policies

• Defining and Editing Group Bookmarks

• Adding a New User, Deleting a User and Editing a User

• Defining and Editing User Policies

• Defining and Editing a User Bookmarks

• Active Directory Authentication Servers for Group Policies and Bookmarks

• LDAP Authentication Domains for Group Policies and Bookmarks

• NT and RADIUS Domain Servers for Group Policies and Bookmarks

Users, Groups and Global Policies

An administrator can define user, group and global policies to predefined network resource objects, IP addresses, address ranges, or all IP addresses and to different SSL VPN services. A specific hierarchy is invoked over which policies take precedence. The SSL VPN Concentrator policy hierarchy is defined as:

1. User Policies take precedence over all Group Policies.

2. Group Policies take precedence over all Global Policies.

v1.0, August 2006

6-1

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

3. If two or more user, group or global policies are configured, the most specific policy takes precedence.

For example, a policy configured for a single IP address takes precedence over a policy configured for a range of addresses. And a policy that applies to a range of IP addresses takes precedence over a policy applied to all IP addresses. If two or more IP address ranges are configured, then the smallest address range takes precedence. Hostnames are treated the same as individual IP addresses

Network Resources are prioritized just like other address ranges. However, the prioritization is based on the individual address or address range, not the entire Network Resource.

For example, let’s assume the following global policy configuration:

• Policy 1: A Deny rule has been configured to block all services to the IP address range

10.0.0.0 - 10.0.0.255.

• Policy 2: A Deny rule has been configured to block FTP access to 10.0.1.2 -

10.0.1.10.

• Policy 3: A Permit rule has been configured to allow FTP access to the predefined network resource, FTP Servers. The FTP Servers network resource includes the following addresses:10.0.0.5 - 10.0.0.20 and ftp.company.com, which resolves to

10.0.1.3.

Assuming that no conflicting user or group policies have been configured, if a user attempted to access:

• An FTP server at 10.0.0.1, the user would be blocked by Policy 1.

• An FTP server at 10.0.1.5, the user would be blocked by Policy 2.

• An FTP server at 10.0.0.10, the user would be granted access by Policy 3. The IP address range 10.0.0.5 - 10.0.0.20 is more specific than the IP address range defined in Policy 1.

• An FTP server at ftp.company.com, the user would be granted access by Policy 3. A single host name is more specific than the IP address range configured in Policy 2

Note: The user would not be able to access ftp.company.com using its IP address

10.0.1.3. The SSL VPN Concentrator policy engine does not perform reverse DNS lookups.

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

The most specific policy will take precedence over less specific policies. For example, a policy that applies to only one IP address will have priority over a policy that applies to a range of IP addresses. If there are two policies that apply to a single IP address, then a policy for a specific service (for example RDP) will take precedence over a policy that applies to all services.

Note: User policies take precedence over all group policies and group policies take

precedence over all global policies, regardless of the policy definition (A user policy that allows access to all IP addresses will take precedence over a group policy that denies access to a single IP address).

To define group access policies:

1. Click Add Policy in the Gr oup Policies section of the Gr oup Settings screen. An Add Policy window will display

Active Directory Authentication Servers for Group Policies and Bookmarks

Active Directory authentication servers support a group and user structure that can be queried when an Active Directory user logs in. This means that you can create policies and bookmarks for Active Directory users at the group level, without needing to define Active Directory users in the SSL VPN Concentrator. When a user logs in, if no corresponding user name is configured in the SSL VPN Concentrator, then it will query the Active Directory server for the list of groups that the user belongs to. If any of the same groups are defined in the SSL VPN Concentrator, then policies and bookmarks for the first Windows Active Directory group that matches a group configured in the SSL VPN Concentrator will be applied to the user.

Once you create an Active Directory domain, you can add groups that correspond with groups on your Active Directory server. If the Active Directory user is configured in the SSL VPN Concentrator, then the SSL VPN Concentrator will ignore the group information provided by the Active Directory and, instead, implement policies and bookmarks based on the user settings and the settings of the group to which the user belongs.

Note: Because other authentication services do not have the same hierarchal structure and

group definitions as Active Directory, if you want to apply specific policies or bookmarks to a group of RADIUS, NT, or LDAP users, you must add each user on the Users and Groups screen.

Group and User Access Policies 6-19

v1.0, August 2006

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

LDAP Authentication Domains for Group Policies and Bookmarks

LDAP (Lightweight Directory Access Protocol) is a standard for querying and updating a directory . Since LDAP supports a multilevel hierarchy (for example, groups or organizational units), the SSL VPN Concentrator can query this information and provide specific group policies or bookmarks based on LDAP attributes. By configuring LDAP attributes, the SSL VPN Concentrator administrator can leverage the groups that have already been configured in an LDAP or Active Directory database, rather than manually recreating the same groups in the SSL VPN Concentrator.

Once an LDAP authentication domain is created, a default LDAP group will be created with the same name as the LDAP domain name. Although additional groups may be added or deleted from this domain, the default LDAP group may not be deleted.

For an LDAP group, you may define LDAP attributes. For example, you can specify that users in an LDAP group must be members of a certain group or organizational unit defined on the LDAP server. Or you can specify a unique LDAP distinguished name.

Note: The Microsoft Active Directory database uses an LDAP organization schema. The

Active Directory database may be queried using Kerberos authentication (the standard authentication type; this is labeled “Active Directory” domain authentication in the SSL VPN Concentrator), NTLM authentication (labeled “NT Domain” authentication in the SSL VPN Concentrator), or using LDAP database queries. So, an LDAP domain configured in the SSL VPN Concentrator can authenticate to an Active Directory server.

To add an LDAP authentication domain, see “Authentication Domains” in Chapter 7.

Sample LDAP Attributes

You may enter up to 4 LDAP attributes per group. The following are some example LDAP attributes of Active Directory LDAP users:

name=”Administrator” memberOf=”CN=Terminal Server Computers,CN=Users,DC=netgearnetworks, DC=net”objectClass=”user” msNPAllowDialin=”FALSE”

6-20 Group and User Access Policies

v1.0, August 2006

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

LDAP Attribute Rules

• If multiple attributes are defined for a group, ALL attributes must be met by LDAP users.

• If no attributes are defined, then any user authorized by the LDAP server can be a member of the group.

• If multiple groups are defined and a user meets all the LDAP attributes for two groups, then the user will be considered part of the group with the most LDAP attributes defined. If the matching LDAP groups have an equal number of attributes, then the user will be considered a member of the group based on the alphabetical order of the groups.

• If an LDAP user fails to meet the LDAP attributes for all LDAP groups configured on the SSL VPN Concentrator, then the user will not be able to log into the portal. So the LDAP attributes feature not only allows the administrator to create individual rules based on the LDAP group or organization, it also allows the administrator to only allow certain LDAP users to log into the portal.

Sample LDAP Users and Attributes Settings

If a user is manually added to a LDAP group, then the user setting will take precedence over LDAP attributes.

For example:

• An LDAP attribute objectClass=”Person” is defined for group Group1 and an LDAP attribute memberOf=”CN=WINS Use rs,DC=netgearnetworks,DC=net” is defined for Group2.

• If user Jane is defined by an LDAP server as a member of the Person object class, but is NOT a member of the WINS Users group, Jane will be a member of the SSL VPN Concentrator Group1.

• But if the administrator manually adds the user Jane to the SSL VPN Concentrator Group2, then the LDAP attributes will be ignored and Jane will be a member of Group2.

Querying an LDAP Server

If you would like to query your LDAP or Active Directory server to find out the LDAP attributes of your users, there are several different methods. From a machine with LDAPsearch tools (for example a Linux machine with OpenLDAP installed) run the following command:

ldapsearch -h 10.0.0.5 -x -D “cn=demo,cn=users,dc=netgearnetworks,dc=net”

-w demo123 -b “dc=netgearnetworks,dc=net” > /tmp/file

Group and User Access Policies 6-21

v1.0, August 2006

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

Where:

• 10.0.0.5 is the IP address of the LDAP or Active Directory server

• “cn=demo,cn=users,dc=netgearnetworks,dc=net” is the distinguished

name of an LDAP user

• demo123 is the password for the user demo

• “dc=netgearworks,dc=net” is the base domain that you are querying

• > /tmp/file is optional and defines the file where the LDAP query results will be

saved.

For further information on querying an LDAP server from a Window server, please see:

NT and RADIUS Domain Servers for Group Policies and Bookmarks

For authentication to RADIUS or Microsoft NT domains (using Kerberos), you can individually define AAA users and groups. This is not required, but it allows you to create separate policies or bookmarks for individual AAA users.

When a user logs in, the SSL VPN Concentrator will validate with the appropriate RADIUS or NT server that the user is authorized to log in. If the user is authorized, the SSL VPN Concentrator will check to see if a user exists in the SSL VPN Concentrator Users and Groups database. If the user is defined, then the policies and bookmarks defined for the user will apply.

For example, if you create a RADIUS domain in the SSL VPN Concentrator called “Miami RADIUS server”, you can add users to groups that are members of the “Miami RADIUS server” domain. These user names must match the names configured in the RADIUS server. Then, when users log in to the portal, policies, bookmarks and other user settings will apply to the users. If the AAA user does not exist in the SSL VPN Concentrator, then only the global settings, policies and bookmarks will apply to the user.

For adding new RADIUS or Microsoft NT domain servers, see “Authentication Domains” in

Chapter 7.

If your users are unable to connect via Active Directory, verify the following:

1. The time settings between the Active Directory server and the SSL VPN Concentrator must be synchronized. Kerberos authentication, used by Active Directory to authenticate clients, permits a maximum of a 15-minute time difference between the Windows server and the client (the SSL VPN Concentrator). The easiest way to solve this issue is to configure Network Time Protocol on the Date and Time screen and check that the server's time settings are also correct.

2. Confirm that your Windows server is configured for Active Directory authentication. If you are using a Window NT 4. 0 server, then your server on ly supp orts NT Domain authentication. Typically , Windows 2000 and 2003 servers are also configured for NT Domain authentication to support legacy Windows clients.

Deleting a Domain

T o delete a domain, click the Delete link in the Domains table for the domain you wish to remove. Once the SSL VPN Concentrator has been updated, the deleted domain will no longer be displayed in the table in the Domains table.

Note: The SSL VPN Concentrator “geardomain” domain cannot be deleted.

Network Resources

This chapter explains how to define network resource groups. Network resources facilitate creating and updating access policies.

Network Resources are groups of host names, IP addresses and IP address ranges. By defining resource objects, you can more quickly configure network policies. This is because you will not need to redefine the same set of IP addresses or address ranges when configuring the same access policies for multiple users.

Defining Network Resources is optional; smaller organizations can choose to create access policies using individual IP addresses or IP networks rather than predefined Network Resources. But for most organizations, it is recommended that you use Network Resources. If your server or network configuration changes, by using Network Resources you can perform an update quickly instead of individually updating all of the user and group policies.

To configure a network policy:

1. Select Network Resources under the Access Administration menu on the left navigation pane. The Network Resources screen will display.

Figure 8-1

2. Click Add Resource. An Add Network Resour ce screen similar to the following will display.

VPN Tunnel Client

This chapter describes the configuration for a VPN Tunnel Client, an SSL VPN client that is deployed from the SSL VPN portal. It covers:

• Adding IP Address Ranges

• Adding Routes for VPN Tunnel Clients

Beyond what is defined in “Logging in to the Management Interface” on page 2-4, the VPN Tunnel Client has some specific operating requirements. For

• Mac OS. VPN Tunnel supports Version 1.4 (Tiger).

• Browsers. The Firefox browser is not supported.

The number of VPN Tunnel Client sessions your installation of SSL VPN Concentrator will support concurrently is dependent on the hardware configuration of your SSL VPN Concentrator server.

SSL VPN Client Configuration

There are several different scenarios you can use to set up SSL VPN client addresses and routes. The following is a simple network setup. For more complex network configurations, see the SSL VPN network scenarios document referenced in

The VPN Tunnel Client provides a PPP (po int-to-point) connection between the client and the SSL VPN Concentrator. When remote users connect using VPN over SSL, a virtual network interface is created with IP settings dynamically assigned by the SSL VPN Concentrator. In addition, DNS and WINS server settings are also assigned by the SSL VPN Concentrator. DNS and WINS settings allow the VPN Tunnel Client to contact machines on the corporate network by host name or domain name. The DNS and WINS settings assigned to the VPN Tunnel Client are configured on the Network screen located under System Configuration on the left navigation pane.

The VPN Tunnel Clien t provi des a point-to-point (PPP) connection and uses proxy ARP requests to locate machines on the remote network. Because the connection is a point-to-point connection, the addresses on the local network and the remote network can overlap. For example:

v1.0, August 2006

Appendix B, “Related Documents”.

9-1

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

• The VPN Tunnel Client cannot contact a server on the corporate network if the VPN Tunnel Client's Ethernet interface shares the same IP address as the server or the SSL VPN Concentrator (i.e., if your laptop has a physical interface address of 10.0.0.45, then you won't be able to contact a server on the remote network that also has the IP address 10.0.0.45).

• You do not want the virtual (PPP) interface address of the VPN Tunnel Client to conflict with addresses on the corporate network. Therefore, configure an IP address range that does not directly overlap with addresses on your local network. So, if 192.168.0.1 through

192.168.0.100 are currently assigned to machines on your local network, then start the client address range at 192.168.0.101 or choose an entirely different subnet altogether.

Adding IP Address Ranges

If you choose a different subnet for the VPN Tunnel Client range than the subnet used by the corporate network, then you must:

1. Add a client route to configure the VPN Tunnel client to connect to the corporate network using the VPN tunnel.

2. Create a static route on the corporate network's firewall to forward traffic intended for the VPN Tunnel Client range to the SSL VPN Concentrator.

Once you have determined the address range you will assign to VPN Tunnel Clients, then define the address range in the SSL VPN Concentrator administrative interface.

To configure SSL VPN Tunnel client address range:

1. Click the VPN Tunnel option under Access Administration in the left navigation pane. The VPN Tunnel Client screen will display.

You may define the IP address range to assign to incoming VPN Tunnel clients in the Client IP Address Range section of the screen. The default range begins with 192.168.251.1 and

ends with 192.168.251.254.

2. Enter the first IP address of the IP address range in the Client Address Range Begin field.

3. Enter the last IP address of the IP address range in the Client Address Range End field.

4. Click Apply to update the configuration.

5. Restart the SSL VPN Concentrator software if VPN Tunnel Clients are actively connected;

this will force the clients to obtain a new virtual IP address. VPN Tunnel Clients will now be able to connect to the SSL VPN Concentrator and receive a

dynamic IP address in the client address range.

Adding Routes for VPN Tunnel Clients

The Add Routes for VPN Tunnel Clients section allows you to define the addresses of devices on your local network. Client routes are only required if the client address range is in a different subnet then the corporate network or if your network has multiple subnets. Client routes inform the VPN Tunnel Clients that other networks are located across the VPN over SSL tunnel by:

• The first VPN Tunnel Client assumes that addresses in the same subnet as the client IP address (PPP interface) are located across the VPN over SSL tunnel.

• The address range in the client subnet. The specific subnet is determined by the class of the IP address.

– Addresses between 1.0.0.0 and 126.255.255.255, are Class A addresses; the VPN Tunnel

Client will assume that all addresses with the same first octet are located across the VPN tunnel.

VPN Tunnel Client 9-3

v1.0, August 2006

NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual

– Addresses between 128.0.0.0 and 191.255.255.255 are Class B addresses; the VPN

Tunnel Client will assume that all addresses with the same first two octets are located across the VPN tunnel.

– Addresses between 192.0.0.0 and 223.255.255.255 are Class C addresses; the VPN

Tunnel Client will assume that all addresses with the same first three octets are located across the VPN tunnel.

The subnet classes for the designated private IP address ranges are:

• Class A subnet: 10.0.0.0 through 10.255.255.255

• Class B subnet: 172.16.0.0 through 172.16.31.255.255

• Class C subnet: 192.168.0.1 through 192.168.255.255

If VPN Tunnel Clients need to connect to addresses on the corporate network that are not in the same subnet as the client address range, then you will need to add client routes.

To add an SSL VPN Tunnel client route:

1. In the Destination Network field under Add Routes for VPN Tunnel Clients section, enter the network address of a local area network or subnet For example, enter 192.168.0.0.

2. Enter the subnet mask of the local area network Subnet Mask field.

3. Click Add Route. The client route will be displayed in the Configured Client Routes table,

as shown in the example in

Figure 9-2.

Note: You will also need to add a static route on your corporate firewall or router that

directs traffic destined for the VPN Tunnel Client address range to the SSL VPN Concentrator.

4. Restart the SSL VPN Concentrator software if VPN Tunnel Clients are currently connected to the SSL VPN Concentrator. Restarting forces clients to reconnect and receive new addresses and routes.

Now users will be able to connect to the SSL VPN Concentrator and receive a virtual IP address from the client address range.

Port Forwarding

This chapter describes the configuration for Port Forwarding, a web-based SSL VPN client that installs transparently and then creates a virtual, encrypted tunnel to the remote network. Using Port Forwarding, mobile users can access mission-critical applications such as email or mapped network drives as if they were located on the corporate network.

This chapter covers:

• Configuring Applications for Port Forwarding

• Configuring Host Name Resolution

Port Forwarding, like VPN Tunnel, is a web-based client that installs transparently and then creates a virtual, encrypted tunnel to the remote network. However, Port Forwarding differs from VPN Tunnel in several ways. For example, Port Forwarding:

• Only supports TCP data, not UDP or other IP protocols.

• Detects and reroutes individual data streams over the Port Forwarding connection rather than opening up a full tunnel to the corporate network. So Port Forwarding is a lighter client than VPN Tunnel and installs more quickly.

• Offers more fine grained management than VPN Tunnel. Administrators define individual applications and resources that will be available to remote users. With VPN Tunnel, administrators must create access policies to block undesirable traffic at the SSL VPN Concentrator rather than at the client level.

Configuring Applications for Port Forwarding

Port Forwarding client detects and reroutes data sent by the remote users to the SSL VPN Concentrator. The Port Forwarding screen allows you to specify the internal addresses and applications that Port Forwarding clients may access. To configure Port Forwarding, you must define the internal host machines and TCP applications available to remote users.

To configure applications for Port Forwarding:

1. From the Access Administration menu in the left navigation pane, select the Port Forwarding option. The Port Forwarding configuration screen will display.
