Steps for Deploying the SSL312 Three basic steps are involved in deploying the ProSafe SSL VPN Concentrator 25 in your network: • Installing the SSL312: choosing a network topology, configuring its IP addressing scheme, connecting the SSL312, and provisioning the SSL certificate. Refer to Chapter 2, “Installing the SSL312”. • Setting up SSL312 user accounts: creating individual user accounts, grouping users by common access privileges, and defining those privileges. Refer to Chapter 3, “Authenticating Users” and Chapter 4, “Setting Up User and Group Access Policies”. • Configuring remote access to corporate network resources through the SSL312: designing the presentation Web portal that will display the available corporate resources to remotely connected users. Refer to Chapter 5, “Configuring the Remote Access Web Portal”. Introduction 1-5 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 1-6 Introduction v2.1, November 2008 Chapter 2 Installing the SSL312 This chapter describes how to install the ProSafe SSL VPN Concentrator 25 SSL312. The installation includes choosing a network topology, configuring the IP addressing scheme, connecting the SSL312, and provisioning the SSL certificate. This chapter includes these topics: • Choosing a Network Topology • Initial Connection to the SSL VPN Concentrator • Accessing the Management Interface • Configuring Basic Network Settings • Installing the SSL VPN Concentrator • Managing Certificates • Steps for Further Configuration Choosing a Network Topology The physical connection of the SSL VPN Concentrator to your network is determined by the network topology you choose. There are two common network topologies for installing the SSL VPN Concentrator: single arm or routing. Variations of these topologies are possible, particularly if your firewall supports a DMZ connection. Single Arm In the single arm, or one port, topology, the SSL VPN Concentrator’s Ethernet Port 1 is connected to your corporate Ethernet network behind your existing firewall, while Ethernet Port 2 is not used. The single active Ethernet port hosts both the encrypted connection to the Internet and the decrypted connection to the corporate network’s resources. As shown in the following figure, encrypted SSL traffic from a remote user passes through the firewall and terminates at the SSL VPN Concentrator, which authenticates the user and displays the portal and resources authorized for that user. The user’s subsequent requests for network 2-1 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual services are decrypted by the SSL VPN Concentrator and relayed to the appropriate corporate network servers. . Corporate Server IP Address 192.168.1.3 Firewall/Router IP Address 192.168.1.254 LAN Subnet 192.168.1.0/24 SSL312 IP Address 192.168.1.1 Figure 2-1 Single arm mode has the advantage of being protected by your firewall. In later steps, you will use the following settings when configuring for single arm operation. • Assign Ethernet Port 1 an IP address on your local network. • Disable Ethernet Port 2. • Disable Routing Mode. • Define a default route to the firewall. • If your firewall performs NAT, you must configure the firewall to forward incoming HTTPS traffic to the IP address of Ethernet Port 1. Note: NETGEAR recommends single arm operation for most networks. Routing In the routing, or two port, topology, the SSL VPN Concentrator is connected in parallel with your existing firewall. Ethernet Port 1 is connected to the untrusted side of your firewall, while Ethernet Port 2 connects to your corporate network. 2-2 Installing the SSL312 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual As shown in the following figure, encrypted SSL traffic from a remote user is sent directly to the SSL VPN Concentrator, which authenticates the user and displays the portal and resources authorized for that user. The user’s subsequent requests for network services are decrypted by the SSL VPN Concentrator and relayed to the appropriate network servers on the corporate network. 10.0.0.10 10.0.0.254 10.0.0.20 66.123.4.80 10.0.0.1 SSL312 Red = Public (untrusted) Green = Local (trusted) Figure 2-1 Routing mode has the advantage of unloading SSL traffic from your firewall. However, your network may not be as well protected since the firewall can not inspect this traffic. In later steps, you will use the following settings when configuring for routing operation. • Assign Ethernet Port 1 a public IP address. • Assign Ethernet Port 2 an IP address on your local network. • Enable Routing Mode. Note: The SSL VPN Concentrator does not perform Network Address Translation (NAT). Also, the SSL VPN Concentrator only enforces access policies on SSL VPN traffic, not on other TCP/IP protocols. Therefore, the SSL VPN Concentrator should always be used in conjunction with a network firewall. Initial Connection to the SSL VPN Concentrator In its factory default state, the SSL VPN Concentrator Ethernet Port 1 IP address is 192.168.1.1 and the Ethernet Port 2 IP address is 10.0.0.1. Unless these default IP addresses are compatible with your network, you must configure and connect a computer directly to Ethernet Port 1 for initial configuration including reassignment of the Ethernet Port IP addresses. This procedure is described in the following steps: Installing the SSL312 2-3 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 1. Prepare a PC with an Ethernet adapter. If this PC is already part of your network, record its TCP/IP configuration settings so that you can restore them later. 2. Configure your PC with a static IP address of 192.168.1.10 and 255.255.255.0 as the subnet mask. 3. Connect an Ethernet cable from your computer to Ethernet Port 1 on the front of the SSL VPN Concentrator. 4. Connect the power cord to the SSL312, turn on the concentrator and verify the following: • The PWR (power) light goes on immediately. • The TEST light goes off after about one minute, indicating that the system has initialized. • One of the Ethernet lights is lit: either the 10 Mbps or the 100 Mbps LED should light showing that a connectivity link as been established Accessing the Management Interface Using the PC with the static IP address configured, you can log into the SSL VPN Concentrator web management interface. The initial administrative setup of the concentrator must be performed using a supported browser listed in “Web Browser Requirements” on page 1-2. The machine used for management is referred to as the “Management Station”. Note: You must have administrative access to the SSL VPN Concentrator to configure the Management Interface settings. To log into the management interface: 1. Connect to the SSL312 by opening your browser and entering https://192.168.1.1 (for the Ethernet Port 1 IP) in the address field. Be sure to type https, not http.. https://192.168.1.1 Figure 2-2 If you are connected to Ethernet Port 2 IP, the default address is https://10.0.0.1. 2-4 Installing the SSL312 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 2.

Log in as admin using the new password that you assigned. You can now continue the configuration of your SSL VPN Concentrator. Managing Certificates Establishing an SSL connection requires that the SSL server, such as your SSL VPN Concentrator, provide a digital SSL certificate to the user’s browser. A certificate is a file that contains: • A public encryption key to be used for encrypting your messages to the server. • Information identifying the operator of the server. • A digital signature confirming the identity of the operator of the server. 2-8 Installing the SSL312 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual You can obtain a certificate from a well-known commercial Certificate Authority (CA) such as Verisign or Thawte, or you can generate and sign your own certificate. Because a commercial CA takes steps to verify the identity of an applicant, a certificate from a commercial CA provides a strong assurance of the server’s identity. A self-signed certificate will trigger a warning from most browsers as it provides no protection against identity theft of the server. Note: If you obtain a certificate from a CA, you must use a Root CA, not an Intermediate CA. Root certificates are signed by the Root CA itself, while Intermediate certificates depend on a verification hierarchy leading back to a Root CA. Your SSL VPN Concentrator contains a self-signed certificate from NETGEAR. NETGEAR recommends that you replace this certificate prior to deploying the SSL VPN Concentrator in your network. From the Certificates menu, you can view the currently loaded certificates, upload a new certificate and generate a Certificate Signing Request (CSR). Obtaining a Certificate from a Certificate Authority To obtain a certificate from a CA, you must generate a Certificate Signing Request (CSR) for your SSL VPN Concentrator. The CSR is a file containing information about your company and about the device that will hold the certificate. Refer to the CA for guidelines on the information you include in your CSR. To generate a new Certificate Signing Request (CSR) file: 1. Under the System Configuration menu in the left navigation pane, select Certificates. The Certificates screen displays.

Upload and enable the certificate according to the instructions later in this chapter. Uploading and Enabling the New Certificate For uploading to the SSL VPN Concentrator, the certificate information must be in a zipped file containing a certificate file named server.crt and a certificate key file named server.key. If the zipped file does not contain these two files, the zipped file will not be uploaded. Any file name will be accepted, but it must have the .zip extension. Note: Do not upload the CSR file to the SSL VPN Concentrator. To upload and enable the new certificate: 1. Under the System Configuration menu in the left navigation pane, select Certificates. The Certificates menu will display as shown in the previous section. 2. In the Import Digital Certificate table, select Browse to locate the zipped digital certificate file on your disk or network drive. 3. Click Upload to save the file to the Cert Description table. Once the certificate has been uploaded, the certificate is displayed in the Current Certificates table. Note: Valid certificates generated by an authorized Certificate Authority (CA), or a non-authorized CA, require a password. Before you enable the certificate and restart the software, be sure to enter the correct certificate password in the Enable Certificate window. The password for the NETGEAR default certificate is password. 2-12 Installing the SSL312 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Figure 2-7 4.

Click Delete do delete the certificate. Note: The Delete button will not be displayed if the SSL certificate is active. To delete a certificate, upload and activate another SSL certificate. Then you can delete the inactive certificate from the View Certificate window. 2-14 Installing the SSL312 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Steps for Further Configuration The next steps in configuring the SSL VPN Concentrator are: • Create authentication domains (Chapter 3, “Authenticating Users”). • Define user and group settings (Chapter 4, “Setting Up User and Group Access Policies”). Installing the SSL312 2-15 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 2-16 Installing the SSL312 v2.1, November 2008 Chapter 3 Authenticating Users Remote users connecting to the SSL VPN Concentrator must be authenticated before being allowed to access the network. The login window presented to the user requires three items: a User Name, a Password, and a Domain selection. The Domain determines the authentication method to be used and the portal layout that will be presented. This chapter explains how to define authentication domains. This chapter describes: • Authentication Domains • Local User Database Authentication • RADIUS and NT Domain Authentication • Configuring for NT Domain Authentication • LDAP Authentication • Kerberos Authentication (Active Directory) • Deleting a Domain If your implementation consists of a small number of users, a single portal layout, and no central authentication server, you can skip this chapter and simply use the default domain “geardomain.” Authentication Domains To view the SSL VPN Concentrator Domains window from the Administrative User Interface, click the Domains option under the Access Administration menu in the left navigation pane. 3-1 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Figure 3-1 All of the configured domains will be listed in the table in the Domains window. The domains are listed in the order in which they were created. By default, the geardomain authentication domain is already defined, using the SSL VPN Concentrator’s local internal user database for user authentication. Additional domains may be created that use the internal user database authentication or require authentication to remote authentication servers. The SSL VPN Concentrator supports RADIUS (PAP, CHAP, MSCHAP, MSCHAPV2, and WiKID), LDAP, NT Domain, and Kerberos authentication in addition to internal user database authentication. Because a portal layout (such as portal pages, themes, banners, etc.) must be associated with a domain, multiple domains are necessary if you wish to display different portal layouts to different users. Local User Database Authentication You can create multiple domains that authenticate users with user names and passwords stored in a local user database on the SSL VPN Concentrator. To add a new authentication domain using the local user database: 3-2 Authenticating Users v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 1. From the Access Administration menu, select Domains. The Domains window will display. Click Add Domain. Figure 3-2 2. From the Authentication Type pull-down menu, select Local User Database. 3. In the Domain Name field, enter a descriptive name for the authentication domain. This is the domain name users will select in order to log into the SSL VPN portal. 4. In the Portal Layout Name pull-down menu, select the name of the layout. The default layout is SSL-VPN. You can define additional layouts in the Portal Layouts screen. 5. Click Apply to update the configuration. Once the domain has been added, the domain is displayed in the table on the Domains screen RADIUS and NT Domain Authentication For authentication to RADIUS or Microsoft NT domains (using Kerberos), you can individually define authentication, authorization, and accounting (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. Authenticating Users 3-3 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 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. When specifying RADIUS domain authentication, you are presented with several authentication protocol choices, as summarized in the following table: Table 3-1. Authentication Protocol Description PAP Password Authentication Protocol (PAP) is a simple protocol in which the client sends a password in clear text. CHAP Challenge Handshake Authentication Protocol (CHAP) executes a three-way handshake in which the client and server trade challenge messages, each responding with a hash of the other’s challenge message that is calculated using a shared secret value. MSCHAP Microsoft CHAP (MSCHAP) is a Microsoft variation of CHAP. MSCHAPv2 MSCHAPv2 is an improved version providing mutual authentication between peers. WiKID WiKID is a key-based two-factor authentication method using public key cryptography. The client sends an encrypted PIN to the WiKID server and receives a one-time passcode with a short expiration period. The client logs in with the passcode. The chosen authentication protocol must be configured on the RADIUS server and on the authenticating client devices. Configuring for RADIUS Domain Authentication To create a domain with RADIUS authentication: 1. From the Access Administration menu, select Domains. The Domains window will display. Click Add Domain. 2. From the Authentication Type pull-down menu, select a RADIUS domain that specifies the authentication method to be used. The Add Domain window displays the fields for a domain for RADIUS authentication. 3-4 Authenticating Users v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Figure 3-3 3. In the Domain Name field, enter a descriptive name for the authentication domain. This is the domain name users will select in order to log into the SSL VPN portal. 4. In the Radius Server Address field, enter the IP address or domain name of the Radius server. 5. If an authentication secret is required by the Radius server, enter it in the Secret Password field. 6. From the Portal Layout Name drop-down menu, select the name of the layout. The default layout is SSL-VPN. You can define additional layouts in the Portal Layouts page. 7. Click Apply to update the configuration. Once the domain has been added, the domain displays in the table on the Domains screen. Configuring for NT Domain Authentication To configure NT Domain authentication: 1.

It may be the same value as the NT Domain Name. 4. In the NT Server Address field, enter the IP address or host and domain name of the server. 5. In the NT Domain Name field, enter the NT authentication domain. This is the domain name configured on the Windows authentication server for network authentication. 3-6 Authenticating Users v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 6. From the Portal Layout Name pull-down menu, select the name of the layout. The default layout is SSL-VPN. You can define additional layouts in the Portal Layouts page. 7. Check the Require CIFS bookmark to home directory check box to automatically allow access to users of this domain and add the home directory path in the field provided. 8. Click Apply to update the configuration. Once the domain has been added, the domain displays in the table in the Domains screen. LDAP Authentication 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 you can add additional groups to or delete groups from this domain, you cannot delete the default LDAP group. For an LDAP group, you can 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 can be queried using Kerberos authentication (the standard authentication type), NTLM authentication (labeled “NT Domain” authentication in the SSL VPN Concentrator), or using LDAP database queries. As a result, an LDAP domain configured in the SSL VPN Concentrator can authenticate to an Active Directory server. To add an LDAP authentication domain, see “Configuring for LDAP Authentication” on page 3-9. Sample LDAP Attributes You can enter up to 4 LDAP attributes per group. The following are some example LDAP attributes of Active Directory LDAP users: Authenticating Users 3-7 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual name=Administrator memberOf=CN=TerminalServerComputers,CN=Users,DC=netgear, DC=net objectClass=user msNPAllowDialin=FALSE 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 you manually add a user to an 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=WINSUsers,DC=netgear,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. 3-8 Authenticating Users v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Querying an LDAP Server To query your LDAP or Active Directory server to find out the LDAP attributes of your users, you can use 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=netgear,dc=net -w demo123 -b dc=netgear,dc=net > /tmp/file where • 10.0.0.5 is the IP address of the LDAP or Active Directory server • cn=demo,cn=users,dc=netgear,dc=net is the distinguished name of an LDAP user • demo123 is the password for the user demo • dc=netgear,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: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/TechRef/8196d68e776a-4bbc-99a6-d8c19f36ded4.mspx Configuring for LDAP Authentication To configure LDAP authentication, click Add Domain. An Add Domain window displays. In the Add Domain window: 1. From the Access Administration menu, select Domains. The Domains window will display. Click Add Domain. 2.

In the Domain Name field, enter a descriptive name for the authentication domain. This is the domain name users will select in order to log into the SSL VPN portal. It can be the same value as the Server Address field. 4. In the Server Address field, enter the IP address or domain name of the server. 5. In the LDAP BaseDN field, enter the search base for LDAP queries. An example of a search base string is: CN=Users,DC=yourdomain,DC=com Note: Do not include quotes (“ ”) in the LDAP BaseDN field. 6. From the Portal Layout Name drop-down menu, select the name of the layout. The default layout is SSL-VPN. You can define additional layouts in the Portal Layouts page. 7. Click Apply to update the configuration. Once the domain has been added, the domain displays in the table on the Domains screen. 3-10 Authenticating Users v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Kerberos Authentication (Active Directory) Kerberos authentication is performed by either a Kerberos authentication server or a Windows Server 2000 or later running Active Directory. Users who have been defined in the Kerberos database can log into the SSL-VPN portal by entering their Kerberos user name and password and selecting the new Kerberos authentication domain from the Domain menu on the SSL VPN login page. To configure Kerberos or Active Directory authentication: 1. From the Access Administration menu, select Domains. The Domains window will display. Click Add Domain. 2. From the Authentication Type menu, select Kerberos. The Kerberos configuration fields will display: Figure 3-6 3. Enter a descriptive name for the authentication domain in the Domain Name field. Users will select this domain when they log into the SSL VPN portal. It can be the same value as the Server Address field or the Kerberos Domain field depending on your network configuration. 4. Enter the IP address or fully qualified domain name of the Kerberos or Active Directory server in the Server Address field. Authenticating Users 3-11 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 5. Enter the Kerberos or Active Directory domain name in the Kerberos Domain field. 6. Enter the name of the layout in the Portal Layout Name field. The default layout is SSL-VPN. (Additional layouts may be defined from the SSL VPN Portal > Portal Layouts screen.) Note: If you selected a portal layout other than SSL-VPN, then the domain will not be displayed on the default login page. Users will need to log in at https:// /portal/ . 7. Click Apply. Once the domain has been added, the domain will be added to the Domains table. Troubleshooting Active Directory Authentication 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 using Kerberos. If you are using a Window NT 4.0 server, then your server only supports NT Domain authentication. Typically, Windows 2000 and 2003 servers are also configured for NT Domain authentication to support legacy Windows clients. Deleting a Domain To 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 appear in the table in the Domains table. Note: The SSL VPN Concentrator “geardomain” domain cannot be deleted. 3-12 Authenticating Users v2.1, November 2008 Chapter 4 Setting Up User and Group 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: • Determine Your Requirements • Users, Groups and Global Policies • Global Policies • Groups Configuration • Users Configuration • Using Network Resource Objects to Simplify Policies Determine Your Requirements The ProSafe SSL VPN Concentrator 25 provides an extremely flexible and granular architecture for managing users and groups. Depending on your requirements, you can implement a simple or complex policy structure. Some general guidelines are: • If you have a small number of users, all with the same privileges, and no central authentication server, you can just add your users to the SSL VPN Concentrator’s local user database, using the default group and domain. • If you use a RADIUS, LDAP, NT or Kerberos authentication server, you do not need to add individual users into the SSL VPN Concentrator unless you wish to define specific policies or bookmarks per user. Configure groups using the same group names as defined in your authentication server. Note: When adding Group/Global policies, if the user is authenticated using an external repository such as Microsoft NT or RADIUS, then the user name must be added to the local database. If the user is authenticate by the LDAP repository, then the user is added to the policy automatically. 4-1 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual • To create complex policies involving groups of host names, IP addresses or IP address ranges, you can define these groups as network objects using Network Resources as described in “Using Network Resource Objects to Simplify Policies” on page 4-22. • To present different portal content to different users (for example, external suppliers), create the new portal layout, then add a new domain, selecting the new portal layout. Users, Groups and Global Policies An administrator can define and apply 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. 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: • 4-2 An FTP server at 10.0.0.1, the user would be blocked by Policy 1. Setting Up User and Group Access Policies v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual • 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. Global Policies You can view and configure the SSL VPN Concentrator Global Policies, Groups and Users by selecting Users and Groups under the Access Administration menu in the left navigation pane.

In the Inactivity Timeout field, enter the number of minutes of inactivity to allow. You can set the inactivity timeout at the user, group and global level. If one or more timeouts are configured for an individual user, the user timeout setting will take precedence over the group timeout and the group timeout will take precedence over the global timeout. Setting the global settings timeout to 0 disables the inactivity timeout for users who do not have a group or user timeout configured. 3. From the Terminal Services SSO pull-down menu, select Enable or Disable. 4-4 Setting Up User and Group Access Policies v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual When Terminal Services Single Sign-On (SSO) is enabled, a user with a domain account will log in only once, and can then access remote servers without being asked again for his credentials. SSO can be enabled or disabled at the user, group and global level. If different settings are configured at different levels, the user level option will take precedence over the group level option and the group level option will take precedence over the global level option. 4.

From the Terminal Services SSO pull-down menu, select Use Global, Enable, or Disable. When Terminal Services Single Sign-On (SSO) is enabled, a user with a domain account will log in only once, and can then access remote servers without being asked again for his credentials. SSO can be enabled or disabled at the user, group and global level. If different settings are configured at different levels, the user level option will take precedence over the group level option and the group level option will take precedence over the global level option. To force the group to use the global level option, select Use Global. 3. In the Inactivity Timeout field, enter the number of minutes of inactivity to allow for users in the group. You can set the inactivity timeout at the user, group and global level. Set the timeout as 0 in the user and group configuration to use the global timeout setting. If multiple timeout settings are configured, the user timeout setting will take precedence over the group timeout and the group timeout will take precedence over the global timeout. 4-10 Setting Up User and Group Access Policies v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual The maximum timeout setting is 232 or over 100,000 minutes, although setting the timeout to 0 on the Global Settings page disables the inactivity timeout (if 0 is also configured as the inactivity timeout for the user and group). 4. Click Apply to save the configuration changes. Defining and Editing Group Policies With group access policies, all traffic is allowed by default. You can create additional allow and deny policies by destination address or address range and by service type. 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 two policies 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. In the Group Policies section of the Group Settings menu, click Add Policy. An Add Policy menu displays. Figure 4-8 2. From the Apply Policy To pull-down menu, select whether the policy will be applied to a predefined network resource, an individual host, a range of addresses or all addresses.

Note: A user cannot be deleted if the user is the only user defined with administrative privileges. Using Network Resource Objects to Simplify Policies Network Resources are groups of host names, IP addresses and IP address ranges. By defining resource objects, you can more quickly create and 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 define a network resource: 1. Under the Access Administration menu on the left navigation pane, select Network Resources. The Network Resources screen displays.

It describes: • Creating the Portal • Portal Options • Adding Portal Layouts • Adding Terminal Services Applications to the Portal • Customizing the Banner • Duplicating and Editing Portal Layouts • Preparing the Client for Using Portal Services If your implementation consists of only a single portal layout, you can simply modify the default layout “SSL-VPN.” Creating the Portal The SSL VPN Portal Layouts screen allows you to create a custom page that remote users will see when they log into the portal. Because the page is completely customizable, it provides the ideal way to communicate remote access instructions, support information, technical contact info or VPN-related news updates to remote users. The page is also well-suited as a starting page for restricted users; if mobile users or business partners are only permitted to access a few files or web URLs, the page you create will only show those links relevant to these users. Portal Layouts are applied by selecting from available layouts in the configuration of a Domain. When you have completed your Portal Layout, you can apply the Portal Layout to one or more authentication domains (see “Authentication Domains” on page 3-1 to apply a Portal Layout to a Domain). You can also make the new portal the default portal for the SSL VPN gateway by selecting the default radio button adjacent to the portal layout name. 5-1 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual Note: The default portal address is https:// . If the default portal is changed from the default (SSL-VPN), you can use the URL address https:// /portal/SSL-VPN to access the administration domain geardomain. The administration domain, geardomain, is attached to the SSLVPN portal layer. To view the Portal Layout screen: Click Portal Layouts under the SSL VPN Portal menu on the left navigation pane. A window similar to the following will display. . Figure 5-1 Portal Options The SSL VPN Concentrator portal can present the remote user with all of the features listed in the table below, or a subset, depending on the configuration by the administrator. Table 5-1. Portal Option Features for Remote Users Feature Description VPN Tunnel An ActiveX-based SSL VPN client for Windows that provides full network connectivity.

Preparing the Client for Using Portal Services In addition to the basic browser requirements described in “Web Browser Requirements” on page 1-2, your client computers may require additional configuration or software. This section provides information to help the remote user prepare the client computer to access the portal services. Terminal Services Client Compatibility To access portal applications made available through Terminal Services, the remote computer must have a compatible Terminal Services client. Microsoft Windows Terminal Services (Remote Desktop Connection) Windows XP, Windows Server 2003, and later Windows versions include a Terminal Services client called Remote Desktop Connection. Computers running earlier Windows versions can install Remote Desktop Connection by networking to a Windows Server 2003 or later (refer to Microsoft support for instructions). NETGEAR recommends that you run at least Windows XP with Service Pack 2. Configuring the Remote Access Web Portal v2.1, November 2008 5-9 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual The Remote Desktop Connection client is launched from the Start button by choosing Start/ Programs/Accessories/Remote Desktop Connection. If your computer uses ActiveX Terminal Services 5.0 with Windows XP Professional SP2, you may see an error stating that you cannot establish a connection to the server. In this case, you will need to download and install an update for Service Pack 2 that provides support for alternative loopback addresses (such as 127.0.02). The update is available at: http://www.microsoft.com/downloads/details.aspx?FamilyID=17d997d2-5034-4bbb-b74dad8430a1f7c8&DisplayLang=en Microsoft Remote Desktop Services Client for the Macintosh To access the functions of the portal using a Macintosh, you will need to install the Microsoft Remote Desktop Services client for the Mac. To download the client, go to: http://www.microsoft.com/mac/otherproducts/otherproducts.aspx?pid=remotedesktopclient Note that the Macintosh will be unable to run Windows applications available on the Windows terminal server. Remote Desktop Services Client for Linux To access the functions of the portal using a Linux computer, you can install RDesktop, an open source client for Windows Terminal Services. To download the client, go to: http://www.rdesktop.org Note that the Linux computer will be unable to run Windows applications available on the Windows terminal server. Creating a User Guide for Portal Services For SSL VPN installations serving many users, it may be helpful to prepare a user guide for accessing the portal and its applications. NETGEAR makes available an application note, created in Microsoft Word, that serves as a template document that can be customized according to the way that your portal is configured. To download the application note, go to: http://documentation.netgear.com/ssl312/enu/202-10208-04/appnote.doc 5-10 Configuring the Remote Access Web Portal v2.1, November 2008 Chapter 6 Configuring the SSL VPN Tunnel Client and Port Forwarding This chapter describes the configuration for the SSL VPN Tunnel Client and for Port Forwarding. When a remote user accesses the SSL VPN Concentrator from a PC that allows ActiveX content, these two powerful features can be activated. For each of these features, the SSL312 installs a small client program on the user’s PC that enables a more direct level of network access than is possible from the browser alone. This chapter includes: • Two Approaches for VPN • SSL VPN Client Configuration • Configuring Applications for Port Forwarding Two Approaches for VPN Two portal features allow direct VPN access to the corporate network. The SSL VPN Tunnel Client allows full network access similar to an IPSec VPN connection. Port Forwarding allows direct network access for selected client-server applications. When a remote user accesses the SSL VPN Portal, one of the listed options is to Establish an SSL VPN Tunnel. When this feature is selected, the SSL VPN Concentrator will install a small VPN Tunnel Client program on the user’s PC that will allow the remote user to virtually join the corporate network. The VPN Tunnel Client provides a PPP (point-to-point) connection between the client and the SSL VPN Concentrator, and a virtual network interface is created on the user’s PC. The SSL VPN Concentrator will assign the PC an IP address and DNS server IP addresses, allowing the remote PC to access network resources in the same manner as if it were connected directly to the corporate network. 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 connections, not UDP or other IP protocols. 6-1 v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual • Detects and reroutes individual data streams to the Port Forwarding connection rather than opening up a full tunnel to the corporate network. • 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. SSL VPN Client Configuration The IP addresses to be assigned to remote VPN Tunnel Clients are configured in the VPN Tunnel menu. Because the connection is a point-to-point connection, you can assign IP addresses from the corporate subnet to the remote VPN Tunnel Clients. The DNS settings assigned to the VPN Tunnel Client are configured in the Network menu. Some additional considerations: • So that the virtual (PPP) interface address of the VPN Tunnel Client does not conflict with addresses on the corporate network, configure an IP address range that does not directly overlap with addresses on your local network. For example, if 192.168.0.1 through 192.168.0.100 are currently assigned to devices on your local network, then start the client address range at 192.168.0.101 or choose an entirely different subnet altogether. • 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 (for example, if your laptop has a network interface IP 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). • If you assign an entirely different subnet to the VPN Tunnel Clients than the subnet used by the corporate network, you must • – Add a client route to configure the VPN Tunnel client to connect to the corporate network using the VPN tunnel. – Create a static route on the corporate network’s firewall to forward local traffic intended for the VPN Clients to the SSL VPN Concentrator. Select whether you want to enable full tunnel or split tunnel support based on your bandwidth: – 6-2 Full tunnel – Sends all of the traffic across the VPN tunnel. Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual – Split tunnel – Sends only traffic destined for the internal network based on the specified client routes. All other traffic is sent to the internet. Split tunnel allows you to manage your company bandwidth by reserving the VPN tunnel for corporate traffic only. Beyond what is defined in “Web Browser Requirements” on page 1-2, the VPN Tunnel Client has some specific operating requirements. For • Mac OS. VPN Tunnel supports Version 1.4 (Tiger). • Browsers. The Firefox browser supports only VPN tunnel, VNC, Network places and Utilities (IE is required for Port Forwarding, Applications, and Terminal Services). Adding IP Address Ranges Determine the address range you will assign to VPN Tunnel Clients, then define the address range in the SSL VPN Concentrator administrative interface. To configure the SSL VPN Tunnel client address range: 1. Under Access Administration in the left navigation pane, select VPN Tunnel. The VPN Tunnel Client screen displays. Figure 6-1 Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 6-3 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual In the Client IP Address Range section of the screen, you can define the IP address range to assign to incoming VPN Tunnel clients. The default range begins with 192.168.251.1 and ends with 192.168.251.254. 2. In the Client Address Range Begin field, enter the first IP address of the IP address range. 3. In the Client Address Range End field, enter the last IP address of the IP address range. 4. Select one of the following: • Enter the Network Subnet to enable Split Tunnel Mode (point-to-point). If you choose a different subnet for the VPN Tunnel client range than the subnet used by the corporate network, then you must: a. Add a client route to configure the VPN Tunnel client to connect to the corporate network using the VPN tunnel. b. Create a static route on the corporate network firewall to forward traffic intended for the VPN clients to the SSL VPN gateway. • Select the Enable Full Tunnel Support check box to enable Full Tunnel mode. The VPN client will install an 0.0.0.0 route on the client machines that will forward all traffic to the SSL Concentrator. 5. Click Apply to update the configuration. 6. Restart the SSL VPN Concentrator software if any VPN Tunnel Clients are actively connected. Restarting will force the clients to obtain a new virtual IP address. VPN Tunnel Clients are now able to connect to the SSL VPN Concentrator and receive a dynamic IP address in the client address range. Note: Be sure to configure DNS addresses in the Network menu. . Adding Routes for VPN Tunnel Clients The VPN Tunnel Clients assume that the following networks are located across the VPN over SSL tunnel: • The subnet containing the client IP address (PPP interface), as determined by the class of the address (Class A, B, or C). • Subnets specified in the Configured Client Routes table. 6-4 Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual If the assigned client IP address range is in a different subnet than the corporate network or if the corporate network has multiple subnets, you must define Client Routes. To add an SSL VPN Tunnel client route: 1. Select the VPN Tunnel menu on the left navigation pane. 2. 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. 3. Enter the subnet mask of the local area network Subnet Mask field. 4. Click Add Route. The client route appears in the Configured Client Routes table, as shown in the figure below. Note: You must also add a static route on your corporate firewall or router that directs local traffic destined for the VPN Tunnel Client address range to the SSL VPN Concentrator. Figure 6-2 Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 6-5 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual 5. 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 are able to connect to the SSL VPN Concentrator and receive a virtual IP address from the client address range. . To delete a VPN Tunnel Client Route: 1. In the Configured Client Routes table, click the Delete link adjacent to the client route. 2. 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. Configuring Applications for Port Forwarding The Port Forwarding screen allows you to specify the internal addresses and TCP applications (port numbers) that will be intercepted by the Port Forwarding client on the user’s PC. The client will reroute this traffic to the SSL VPN Concentrator. To configure Port Forwarding, you must define the internal host machines and TCP applications available to remote users. 6-6 Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual To configure applications for Port Forwarding: 1.

Users can specify the port number together with the host name or IP address. Configuring Host Name Resolution Once the server and port information has been configured, remote users will be able to access private network servers using Port Forwarding. As a convenience for users, the SSL VPN Concentrator administrator can also specify host name to IP address resolution for network servers. Host Name Resolution allows users to access TCP applications at familiar addresses such as mail.mycompany.com or ftp.mycompany.com rather than by IP addresses. To add a host name for client name resolution: 1. In the Configured Host Names for Port Forwarding section, enter an IP address in the Local Server IP Address field. The address should already be defined in the Configured Applications for Port Forwarding table. 2. In the Fully Qualified Domain Name field, enter a domain name of the internal server. 3. Click Apply to submit the host-to-name mapping. The IP address and domain name should appear in the Configured Host Names for Port Forwarding table. Now, remote users will be able to securely access network applications once they have logged into the SSL VPN portal and launched Port Forwarding. 6-8 Configuring the SSL VPN Tunnel Client and Port Forwarding v2.1, November 2008 Chapter 7 Additional System Configuration This chapter describes additional network and configuration management functions provided by the Web Management Interface.
