Page 22 An Introduction to Zones and Interfaces An Introduction to Zones and InterfacesZones split a network infrastructure into logical areas, each with its own set of usage rules, security services, and policies. Most networks include multiple definitions for zones, including those for trusted, untrusted, public, encrypted, and wireless traffic.Some basic (default) zone types include:WAN—Untrusted resources outside your local network.LAN—Trusted local network resources.fWLAN—Local wireless network resources originating from SonicWALL wireless enabled appliances.DMZ—Local network assets that must be accessible from the WAN zone (such as Web and FTP servers).VPN—Trusted endpoints in an otherwise untrusted zone, such as the WAN.The security features and settings that zones carry are enforced by binding a zone to one or more physical interfaces (such as, X0, X1, or X2) on the SonicWALL TZ 210 series appliance.The X1 and X0 interfaces are preconfigured as WAN and LAN respectively. The remaining ports (X2-X6) are also LAN ports by default, however, these ports can be configured to meet the needs of your network, either by using basic zone types (WAN, LAN, WLAN, DMZ, VPN) or configuring a custom zone type to fit your network requirements (Gaming Console Zone, Wireless Printer Zone, Wireless Ticket Scanner Zone, and more).Wireless ClientsWireless DevicesWireless (WLAN)Hotel / Home OceFront Lobby Sales MarketingX1 WANX0 LANW0 WLANTZ_210_GSG.book Page 22 Thursday, November 13, 2008 7:41 PM
SonicWALL TZ 210 Series Getting Started Guide Page 23SonicWALL Wireless FirewallingWhen a wireless device uses an access point to communicate with a device on another subnet or on a completely different network, traffic between the devices is forced to traverse the network gateway. This traversal enables Unified Threat Management (UTM) services to be enforced at the gateway.Standard practice for wireless firewalling (where one wireless client is communicating with another) bypasses many of the critical UTM security services. The illustration below shows the standard practice for wireless firewalling. Many security products on the market share this potential vulnerability when two users connected by a common hub or wireless access point wish to exchange data.SonicWALL addresses this security shortcoming by managing the SonicPoint access points from the UTM appliance. This allows complete control of the wireless space, including zone enforcement of security services and complete firewalling capabilities, as shown in the illustration below.WLAN ZoneSecurity Services?Content Filtering ServiceClient Anti-Virus EnforcementGateway Anti-VirusGateway Anti-SpywareIntrusion Prevention ServiceOther Security ApplianceWLAN Zone Security ServicesSonicWALL TZ 210series applianceSonicWALL SonicPoint**SonicPoint needed for wireless access on TZ 210 wired modelsContent Filtering ServiceClient Anti-Virus EnforcementGateway Anti-VirusGateway Anti-SpywareIntrusion Prevention ServiceSONICPOINTTZ_210_GSG.book Page 23 Thursday, November 13, 2008 7:41 PM
Page 24 Configuring Interfaces Configuring InterfacesInterfaces, also known as ports, are physical network connections that can be configured to provide different networking and security features based on your network needs.Note: For more information on Zone types, see “An Introduction to Zones and Interfaces” on page 22.This section contains the following sub-sections:•Configuring an Interface - page 24•PortShield Wizard - page 25•Manual PortShield Configuration - page 26Configuring an InterfaceThe SonicOS Enhanced Web-based management interface allows you to configure each individual Ethernet port (from X2-X6) with its own security settings through the use of zones. To configure a network interface:1. In the Network > Interfaces panel, click the Configure button for the interface you wish to configure. The Edit Interface window displays.Note: If only X0 and X1 interfaces are displayed in the Interfaces list, click the Show PortShield Interfaces button to show all interfaces.2.

SonicWALL TZ 210 Series Getting Started Guide Page 27Creating Network Access RulesA Zone is a logical grouping of one or more interfaces designed to make management a simpler and more intuitive process than following a strict physical interface scheme.By default, the SonicWALL security appliance’s stateful packet inspection allows all communication from the LAN to the Internet, and blocks all traffic from the Internet to the LAN. The following behaviors are defined by the “Default” stateful inspection packet access rule enabled in the SonicWALL security appliance: To create an access rule:1. On the Firewall > Access Rules page in the matrix view, select two zones that will be bridged by this new rule.2. On the Access Rules page, click Add. The access rules are sorted from the most specific to the least specific at the bottom of the table. At the bottom of the table is the Any rule. Note: SonicWALL’s default firewall rules are set in this way for ease of initial configuration, but do not reflect best practice installations. Firewall rules should only allow the required traffic and deny all other traffic.

Configure the other settings on the Advanced tab as explained below:• In the TCP Connection Inactivity Timeout (minutes) field, set the length of TCP inactivity after which the access rule will time out. The default value is 15 minutes.•In the UDP Connection Inactivity Timeout (minutes) field, set the length of UDP inactivity after which the access rule will time out. The default value is 30 minutes.• In the Number of connections allowed (% of maximum connections) field, specify the percentage of maximum connections that is allowed by this access rule. The default is 100%. • Select Create a reflexive rule to create a matching access rule for the opposite direction, that is, from your destination back to your source.7. Click on the QoS tab to apply DSCP marking to traffic governed by this rule.8. Click OK to add the rule. Address ObjectsAddress Objects are one of four object classes (Address, User, Service, and Schedule) in SonicOS Enhanced. Once you define an Address Object, it becomes available for use wherever applicable throughout the SonicOS management interface. For example, consider an internal Web server with an IP address of 67.115.118.80. Rather than repeatedly typing in the IP address when constructing Access Rules or NAT policies, you can create an Address Object to store the Web server’s IP address. This Address Object, “My Web Server,” can then be used in any configuration screen that employs Address Objects as a defining criterion. Available Address Object types include the following:•Host – Define a single host by its IP address. •Range – Define a range of contiguous IP addresses. • Network – Network Address Objects are like Range objects in that they comprise multiple hosts, but rather than being bound by specified upper and lower range delimiters, the boundaries are defined by a valid netmask. •MAC Address – Allows for the identification of a host by its hardware address. •FQDN Address – Fully Qualified Domain Names (FQDN) Address Objects allow for the identification of a host by its domain name, such as www.sonicwall.com. TZ_210_GSG.book Page 29 Thursday, November 13, 2008 7:41 PM
Page 30 Address Objects Tip: SonicOS Enhanced provides a number of default Address Objects that cannot be modified or deleted. You can use the default Address Objects when creating a NAT policy, or you can create custom Address Objects to use. All Address Objects are available in the drop-down lists when creating a NAT policy.Creating an Address ObjectThe Network > Address Objects page allows you to create and manage your Address Objects. You can view Address Objects in the following ways using the View Style menu:•All Address Objects – displays all configured Address Objects. •Custom Address Objects – displays Address Objects with custom properties. •Default Address Objects – displays Address Objects configured by default on the SonicWALL security appliance. To add an Address Object:1. Navigate to the Network > Address Objects page.2. Below the Address Objects table, click Add.3. In the Add Address Object dialog box, enter a name for the Address Object in the Name field. 4. Select the zone to assign to the Address Object from the Zone Assignment drop-down list. 5. Select Host, Range, Network, MAC, or FQDN from the Type menu. -For Host, enter the IP address in the IP Address field. -For Range, enter the starting and ending IP addresses in the Starting IP Address and Ending IP Address fields. -For Network, enter the network IP address and netmask in the Network and Netmask fields.-For MAC, enter the MAC address in the MAC Address field. -For FQDN, enter the domain name for the individual site or range of sites (with a wildcard) in the FQDN field.6. Click OK.TZ_210_GSG.book Page 30 Thursday, November 13, 2008 7:41 PM
SonicWALL TZ 210 Series Getting Started Guide Page 31Network Address TranslationThe Network Address Translation (NAT) engine in SonicOS Enhanced allows users to define granular NAT policies for their incoming and outgoing traffic. By default, the SonicWALL security appliance has a preconfigured NAT policy to perform Many-to-One NAT between the systems on the LAN and the IP address of the WAN interface. The appliance does not perform NAT by default when traffic crosses between the other interfaces. You can create multiple NAT policies on a SonicWALL running SonicOS Enhanced for the same object – for instance, you can specify that an internal server uses one IP address when accessing Telnet servers, and uses a different IP address for all other protocols. Because the NAT engine in SonicOS Enhanced supports inbound port forwarding, it is possible to access multiple internal servers from the WAN IP address of the SonicWALL security appliance. The more granular the NAT Policy, the more precedence it takes. Before configuring NAT Policies, you must create all Address Objects that will be referenced by the policy. For instance, if you are creating a One-to-One NAT policy, first create Address Objects for your public and private IP addresses. Configuring NAT PoliciesNAT policies allow you to control Network Address Translation based on matching combinations of Source IP address, Destination IP address, and Destination Services. Policy-based NAT allows you to deploy different types of NAT simultaneously. The following NAT configurations are available in SonicOS Enhanced:• Many-to-One NAT Policy• Many-to-Many NAT Policy• One-to-One NAT Policy for Outbound Traffic• One-to-One NAT Policy for Inbound Traffic (Reflexive)• One-to-Many NAT Load Balancing• Inbound Port Address Translation via One-to-One NAT Policy• Inbound Port Address Translation via WAN IP AddressTZ_210_GSG.book Page 31 Thursday, November 13, 2008 7:41 PM
Page 32 Network Address Translation This section describes how to configure a One-to-One NAT policy. One-to-One is the most common NAT policy used to route traffic to an internal server, such as a Web server. Most of the time, this means that incoming requests from external IP addresses are translated from the IP address of the SonicWALL security appliance WAN port to the IP address of the internal Web server. The following example configuration illustrates the use of the fields in the Add NAT Policy procedure. To add a One-to-One NAT policy that allows all Internet traffic to be routed through a public IP address, two policies are needed: one policy for the outbound traffic, and one policy for the inbound traffic. To add the components of a One-to-One NAT policy, perform the following steps:1. Navigate to the Network > NAT Policies page. Click Add. The Add NAT Policy dialog box displays. 2. For Original Source, select Any.3. For Translated Source, select Original.4. For Original Destination, select X0 IP.5. For Translated Destination, select Create new address object and create a new address object using WAN for Zone Assignment and Host for Type.6. For Original Service, select HTTP.7. For Translated Service, select Original.8. For Inbound Interface, select X0.9. For Outbound Interface, select Any.10. For Comment, enter a short description.11. Select the Enable NAT Policy checkbox.12. Select the Create a reflexive policy checkbox if you want a matching NAT policy to be automatically created in the opposite direction. This will create the outbound as well as the inbound policies.13. Click Add.For more information on creating NAT policies, refer to the SonicOS Enhanced Administrator’s Guide.

Page 40 Public Server on DMZ Connecting the SonicPointWhen a SonicPoint unit is first connected and powered up, it attempts to find a SonicOS device with which to peer. If it is unable to find a peer SonicOS device, it will enter into a stand-alone mode of operation with a separate stand-alone configuration allowing it to operate as a standard Access Point.If the SonicPoint locates a peer SonicOS device, such as your SonicWALL TZ 210 series appliance, the two units perform an encrypted exchange and the profile assigned to the relevant wireless zone is used to automatically configure (provision) the newly added SonicPoint unit. To connect the SonicPoint:1. Using a CAT 5 Ethernet cable, connect the SonicPoint to the interface that you configured. Then connect the SonicPoint to a power source.2. In the SonicOS user interface on the SonicPoint > SonicPoints page, click the Synchronize SonicPoints button. The SonicWALL appliance downloads a SonicPoint image from the SonicWALL back-end server.3. Follow the instructions in the SonicPoint wizard. Be sure to select the same authentication type and enter the same keys or password that you configured in SonicOS.Note: For more information about wireless configuration, see the SonicOS Enhanced Administrator’s Guide.Public Server on DMZThis section provides instructions for configuring your SonicWALL TZ 210 series appliance to support a public Web server on a DMZ zone. A Web server can be placed on the LAN by completing the server wizard, which creates the proper address objects and rules for safe access. Many network administrators, however, choose to place the Web server on a DMZ, as it provides a dedicated Ethernet interface for added security and bandwidth management.

Page 46 Configuring High Availability About High AvailabilityIn this scenario, one SonicWALL TZ 210 series appliance operates as the Primary gateway device and the other acts as the Backup. Once configured for High Availability, the Backup SonicWALL contains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA interfaces on each appliance.During normal operation, the Primary SonicWALL is in Active mode and the Backup SonicWALL is in Idle mode. If the Primary device loses connectivity, the Backup SonicWALL transitions to Active mode and assumes the configuration and role of the Primary gateway device. This automatic failover ensures a reliable connection between the protected network and the Internet. After a failover to the Backup appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated.Initial HA SetupBefore you begin the configuration of HA on the Primary SonicWALL security appliance, perform the following setup:1. On the back panel of the Backup SonicWALL security appliance, locate the serial number and write the number down. You need to enter this number in the High Availability > Settings page.2. Verify that the Primary SonicWALL appliance is registered and licensed for SonicOS Enhanced and the desired SonicWALL security services. 3. Associate the two SonicWALL appliances as HA Primary and HA Secondary on MySonicWALL, for license synchronization. 4. Make sure the Primary SonicWALL and Backup SonicWALL security appliances’ LAN, WAN and other interfaces are properly configured for failover.5. Connect the X6 ports on the Primary SonicWALL and Backup SonicWALL appliances with a CAT 5 Ethernet cable. The Primary and Backup SonicWALL security appliances must have a dedicated connection.6. Power up the Primary SonicWALL security appliance, and then power up the Backup SonicWALL security appliance.7. Do not make any configuration changes to the Primary’s X6 interface; the High Availability configuration in an upcoming step takes care of this issue.

SonicWALL TZ 210 Series Getting Started Guide Page 47HA License Synchronization OverviewYou can configure HA license synchronization by associating two SonicWALL security appliances as HA Primary and HA Secondary on MySonicWALL. Note that the Backup appliance of your HA pair is referred to as the HA Secondary unit on MySonicWALL. You need only purchase a single license for SonicOS Enhanced, a single Support subscription, and a single set of security services licenses for the HA Primary appliance. These licenses are shared with the HA Secondary appliance. Only consulting services such as the SonicWALL GMS Preventive Maintenance Service license are not shared. See Registering and Licensing Your Appliance on MySonicWALL - page 10. License synchronization is used during HA so that the Backup appliance can maintain the same level of network protection provided before the failover. To enable HA, you can use the SonicOS UI to configure your two appliances as a HA pair in Active/Idle mode.MySonicWALL provides several methods of associating the two appliances. You can start by registering a new appliance, and then choosing an already-registered unit to associate it with. You can associate two units that are both already registered. Or you can select a registered unit and then add a new appliance with which to associate it.Note: After registering new SonicWALL appliances on MySonicWALL, you must also register each appliance from the SonicOS management interface by clicking the registration link on the System > Status page. This allows each unit to synchronize with the SonicWALL license server and share licenses with the associated appliance.TZ_210_GSG.book Page 47 Friday, November 14, 2008 10:29 AM
