3.4 Network object 3.4.1 Security zone 3.4.1.1 Introduction to security zone Traditional firewall policies are configured based on packet inbound and outbound interfaces on early dual-homed firewalls. With the development of firewalls, they can not only connect the internal and external network, but also connect the internal network, external network, and the Demilitarized Zone (DMZ). Also, they are providing high-density ports. A high-end firewall can provide dozens of physical interfaces to connect multiple logical subnets. In this networking environment, traditional interface-based policy configuration mode requires configuration of a security policy for each interface, which brings great working loads for administrators and thus increases probability for introducing security problems due to improper configurations. The industry-leading firewalls solve the above problems by implementing security policies based on security zones. A security zone is an abstract conception. It can include physical interfaces and logical interfaces, and also Trunk interface + VLAN. Interfaces added to the same security zone have consistent security needs. Therefore, an administrator can classify interfaces (assign them to different zones) based on their security needs, thus implementing hierarchical policy management. For example, on the firewall in the following figure, the administrator can add the interface that connects the R&D area to Zone_RND, and the interface connecting the servers to Zone_DMZ. In this way, the administrator only needs to deploy security policies in the two zones. If the network changes in the future, the administrator only needs to adjust the interfaces in a certain zone, without modifying the security policies. The security zone management feature not only simplifies policy maintenance but also separates network services from security services. 3.4.1.2 Security zone To enter the security zone page, you can choose Basic> Network > Network object > Security zone from navigation tree, as shown in Figure3-19. Figure3-19 Security zone Table3-1 describes the configuration items of the security zone. 3-62

Network requirement Figure3-20 Network diagram for configuring security zones 2. A company uses Device as the network border firewall device to connect the internal network and the Internet and to provide WWW and FTP services to the external network. You need to perform some basic configurations for the zones of the firewall to prepare for the configurations of the security policies. The internal network is a trust network and can access the server and the external network. You can deploy the internal network in the Trust zone with a higher priority and connect the interface eth0/0 on Device to the external network. The external network is an 3-63

untrusted network, and you need to use strict security rules to control access from the external network to the internal network and the server. You can deploy the external network in the Untrust zone with a lower priority and connect the interface gige 0_0 on Device to the external network. If you deploy the WWW server and the FTP server on the external network, security cannot be ensured; if you deploy them on the internal network, the external illegal users may use the security holes to attack the internal network. Therefore, you can deploy the servers in the DMZ zone with a priority between Trust and Untrust, and connect the Ethernet interface eth0/1 on Device to the servers. In this way, the server in the DMZ zone can access the external network in the Untrust zone with a lower priority, but when it accesses the internal network in the Trustzone with a higher priority, its access is controlled by the security rules. 3. Configuration procedure: By default, the system has created the Trust, DMZ and Untrust zones, defined the priority of these zones. (1) Deploy the Trustzone. Select Basic> Network > Network object > Security zone from navigation tree to enter the security zone interface, then select the interface eth0_0 for the trust zone, and then click Ok button.

After you configured IPv4 static routing, data packets will be transmitted to the destination according to your requirement. 3.9.2 Configure static route 3.9.2.1 Introduction to static route Static route is a kind of special route that configured by administrator manually. After static route is configured, data packets go to the specific destination will be forwarded to the paths designated by administrator. In a simple network, network communication can be realized only by configure the static route. If you set and use static route properly, it can improve the network performance and guarantee bandwidth for important applications. When you configure static route, you should understand the following: 1. Destination IP address and mask When you configure static route, destination IP address and mask must be in dotted decimal notation format. 2. Outbound interface and next hop When you configure static route, you can specify the outbound interface and next hop. Whether you specify the outbound interface or next hop, you should depend on the real condition. Routing cannot take effect if the next hop is local interface IP address. 3-73

In actual, all route entries have their explicit next hop addresses. When data packet are sent, their destination address will be looked up in the routing table and find out which route can be matched. Only if you specify the next hop, link layer find the corresponding layer address and forward data packet. 3. Priority You can specify different priorities for different static routes, so that you can flexibly use the route management policy. Such as: configuring multiple routes to the same destination, if you specify the routes with same priority, it can realize load sharing, if you specify different the routes with different priority, then route back up can be realized.

RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15. This hop limit, however, also limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and used to deprecate inaccessible, inoperable, or otherwise undesirable routes in the selection process. 3.10.5.2 Configure RIP To enter the RIP page, you can choose Basic> Network > IPv4 unicast routing > RIP from navigation tree, as shown in Figure3-46.

3.10.6 OSPF Open Shortest Path First (OSPF) is a link state interior gateway protocol developed by the OSPF working group of the Internet Engineering Task Force (IETF). OSPF has the following features: Wide scope: Supports networks of various sizes and up to several hundred routers in an OSPF routing domain. Fast convergence: Transmits updates instantly after network topology changes for routing information synchronization in the AS. Loop-free: Computes routes with the shortest path first (SPF) algorithm according to collected link states, so no route loops are generated. Area partition: Allows an AS to be split into different areas for ease of management and routing information transmitted between areas is summarized to reduce network bandwidth consumption. Equal-cost multi-route: Supports multiple equal-cost routes to a destination. Routing hierarchy: Supports a four-level routing hierarchy that prioritizes routes into intra-area, inter-area, external Type-1, and external Type-2 routes. Authentication: Supports interface-based packet authentication to ensure the security of packet exchange. Multicast: Supports multicasting protocol packets on some types of links. 3.10.6.1 OSPF To enter the OSPF page, you can choose Basic> Network > IPv4 unicast routing > OSPF from navigation tree, as shown in Figure3-48.

3.14 Policy-based routing 3.14.1 Introduction to policy-based routing The policy-based routing (PBR) is a routing mechanism based on user-defined policies that used to modify next hoop address and marketing packet to provide different network service. When the device transmitted packets, it will look up the route table of forward by route-policy before route, if packets are not matched, the device will look up the static route table, if the packets are not matched, the device will look up the route table of forward by route-policy after route. The policy-based routing (PBR) of DPtech is a technology that recognize different network packets thus forward these packets as the policy created in advance. PBR can classify the network packets according different key field and decide which policy-based routing should be used. It can effectively control network streams and behaviors. PBR is on the IP layer, before IP forwarded, if a massage match with a PBR policy, it will execute relatively action, the actions includes redirect to the nexthop, remark (such as TOS, IP priority, DSCP), and then according to destination IP address of the replaced packet of the nexthop to look up FIB table to do IP forwarding. 3.14.2 IPv6 policy-based routing 3.14.2.1 Policy-based routing To enter the policy-based routing page, you can choose Basic> Network >Policy-based routing from navigation tree, as shown in Figure3-103.

3.16 ARP Configuration Address Resolution Protocol (ARP) is the protocol that converts IP address to the Ethernet MAC address. In local area network, when the host or other network device send data to the other host or device, they must know the network layer address (IP address) of each other. But only the IP address is not enough, because IP data packets runs encapsulated by line protocol, so that the sender must know the receiver s physical IP address and needs the IP address and physical address mapping relationship. ARP protocol is used for this kind of requirement. 3.16.1 Display ARP 3.16.1.1 Display ARP To enter the display ARP page, you can choose Basic> Network >ARP > Display ARP, as shown in Figure3-119.

The NAT64 server is the endpoint for at least one IPv4 address and an IPv6 network segment of 32-bits (for instance 64:ff9b::/96, that is NAT64 prefix). The IPv6 client embeds the IPv4 address it wishes to communicate with using these bits, and sends its packets to the resulting address. The NAT64 server then creates a NAT-mapping between the IPv6 and the IPv4 address, allowing them to communicate. 4-152

Chapter 12 High Availability 12.1 VRRP High availability module provides the following features: VRRP Hot standby Interface synchronization group To enter the VRRP interface, you can choose Service > High availability > VRRP, as shown in Figure12-1. Figure12-1 High availability 12.1.1 Introduction to VRRP Group During data communication process, software and hardware error may result network disconnection, causing data transmission failure. To avoid data communication disconnected, DPtech FW has provides Virtual Router Redundancy Protocol (VRRP) technology using back up solution when communication line or device failure, so that it ensure data communication smoothly and enhance network robustness and availability. Enhancing local network and outside network connection availability, VRRP is fit for the local area network which support multicast and broadcast (such as Ethernet). Through many devices forming a back up group, they have an exit gateway for the local network and they are all transparent inside the local network. In the back up group, if an FW device failure, it will be substituted by other device. So that the local host can still work without any modification, greatly enhance network communication availability. To enter the high availability interface, you can choose Service > High availability > VRRP, as shown in Figure12-2. 12-253

Figure12-2 VRRP configuration Table12-1 describes the configuration items of VRRP. Table12-1 VRRP configuration items VRID Virtual IP Interface Authentication mode Advanced configuration Virtual router identification. A virtual router consists of a group of routers with same VRID. Virtual IP address: virtual router IP address. A virtual router has one or several IP addresses. Configure VRRP backup group interface, example:eth0_7. Allows you to select an authentication method, including None, simple text and MD5. None authentication: No authentication is performed for any VRRP packet, without security guarantee. Simple text authentication: You can adopt the simple text authentication mode in a network facing possible security problems. A router sending a VRRP packet fills an authentication key into the packet, and the router receiving the packet compares its local authentication key with that of the received packet. If the two authentication keys are the same, the received VRRP packet is considered valid; otherwise, the received packet is considered an invalid one. MD5 authentication: You can adopt MD5 authentication in a network facing severe security problems. The router encrypts a VRRP packet to be sent using the authentication key and MD5 algorithm and saves the encrypted packet in the authentication header. The router receiving the packet uses the authentication key to decrypt the packet and checks whether the validity of the packet. 1.Configure elect parameter: Priority: VRRP determines the role (master or backup) of each router in a virtual router by priority. Hello interval: Configure Hello packet time interval. Non-preemptive mode: the backup working in non-preemptive mode remains as a backup as long as the master does not fail. The backup will not become the master even if the former is configured with a higher priority. Preemptive mode: the backup working in preemptive mode compares the priority in the packet with that of its own when a backup receives a VRRP advertisement. If its priority is higher than that of the master if preempts as the master; otherwise, it remains a backup. 12-254

2.Configure tracking interface: 3. Configure monitor IP: Status Operation Displays the relationship of master and server. Click Add button or the delete button that you can add or delete an entry of the VRRP configuration. To configure the VRRP configuration, you can take the following steps: Configure a number for the back up group ID number, the range is from 0 to 255, example: 1 Configure virtual IP address for the back up group, example: 2.2.2.1 Select backup group interface, example: eth0_7 Select an authentication method including none, text, and MD5 In the advanced configuration column, configure master elect priority, announce packet sending interval, master preempt mode, and master preempt delay configuration, example: master elect priority 20, announcement packet interval:1s, master preempt mode: preempt, master preempt delay: 0s After you finished the above steps, click Confirm button in the upper right corner on the webpage. Note: Backup group ID number must be same in the same backup group.

Figure12-4 Monitoring 12.1.4 BFD Option To protect key applications, a network is usually designed with redundant backup links. Devices need to quickly detect communication failures and restore communication through backup links as soon as possible. On some links, such as POS links, devices detect link failures by sending hardware detection signals. However, some other links, such as Ethernet links, provide no hardware detection mechanism. In that case, devices can use the hello mechanism of a protocol for failure detection, which has a failure detection rate of more than one second. Such a rate is too slow for some applications. Some routing protocols, such as OSPF and IS-IS, provide a fast hello mechanism for failure detection, but this mechanism has a failure detection rate of at least one second and is protocol-dependent. To enter the BFD option interface, you can choose Service > High availability >VRRP >BFD option, as shown in the Figure12-5. Figure12-5 BFD option 12-256
