Page 74 Configuring the System Operating Modes The Hurricane 9200/S can operate as a router, a bridge, or both. The system operating mode is determined by how you configure the LAN and WAN interfaces to exchange data within your network and with your ISP. This chapter provides an overview of how routers and bridges work, and explains how to configure the device interfaces and other settings to meet the needs of your network and ISP connection type.
Page 75 Chapter 6. Configuring the System Operating Modes Routers use a higher-layer protocol than bridges use to determine how to pass data between two networks. Routers such as the Hurricane 9200/S operate based on the Internet Protocol and use IP addresses to identify where to send data.

Page 91 Viewing System IP Addresses and IP Performance Statistics The interfaces on the Hurricane 9200/S that communicate with other network and Internet devices are identified by unique Internet protocol (IP) addresses. You can use the Configuration Manager to view the list of IP addresses that your device uses, and to view other system and network performance data.

This chapter provides an overview of DHCP and instructions for implementing it on your network. > # , ! DHCP is a protocol that enables network administrators to centrally manage the assignment and distribution of IP information to computers on a network.

Page 95 Chapter 8. Configuring Dynamic Host Configuration Protocol Before you begin, be sure to configure your PCs to accept DHCP information assigned by a DHCP server. See “Quick Start Part 2 — Configuring Your Computers,” for instructions. Note To set up DHCP server, you first define the ranges of IP addresses that you want to be distributed to your PCs, called DHCP server address pools.
Page 96 Hurricane 9200/S ADSL Ethernet Router User’s Guide The DHCP server distributes addresses to computers connected to one of its interfaces only when that interface is in the same subnet as the pool addresses. In the examples shown above, the IP addresses in pool 0 would be assigned only over the Ethernet and USB interfaces, and the addresses in pool 1 would only be assigned only over the Wireless LAN interface.

When a PC user types a domain name into a browser, the PC must first send a request to a DNS server to obtain the equivalent IP address.
Page 104 Hurricane 9200/S ADSL Ethernet Router User’s Guide When you specify the Hurricane 9200/S s LAN interface IP address as the DNS address, then the device automatically performs “DNS relay”; i.e., because the device itself is not a DNS server, it forwards domain name lookup requests it receives from the LAN PCs to a DNS server at the ISP.

Among several alternative routes, the one with the lowest hop count is considered the fastest path. For example, if you assign this port a metric of 1, then RIP will add 1 to the hop count when calculating a route that passes through this port.

Page 118 Hurricane 9200/S ADSL Ethernet Router User’s Guide The NAT rule could further be defined to disguise the source port in the data packet (i.e., change it to another number), so that outside computers will not be able to determine the actual port from which the packet originated.

Page 126 Hurricane 9200/S ADSL Ethernet Router User’s Guide 4. Enter a Rule ID. The Rule ID determines the order in which rules are invoked (the lowest numbered rule is invoked first, and so on). If you define two or more rules that act on the same set of IP addresses, be sure to assign the Rule ID so that the higher priority rules are invoked first.
Page 127 Chapter 12. Configuring Network Address Translation @ % # & % You can create an RDR rule to make a computer on your LAN, such as a Web or FTP server, available to Internet users without having to obtain a public IP address for that computer. The computer’s private IP address is translated to your public IP address in all incoming and outgoing data packets.
Page 128 Hurricane 9200/S ADSL Ethernet Router User’s Guide Follow these instructions to add an RDR rule (see steps 1-4 under "The NAPT rule" on page 125 for specific instructions corresponding to steps 1 and 2 below): 1. Display the NAT Rule – Add Page, select RDR as the Rule Flavor, if necessary, and enter a Rule ID.
Page 129 Chapter 12. Configuring Network Address Translation A port ID identifies the specific function of the computer connected to it, and therefore can limit the types of data that pass to and from the computer. For example, Web (HTTP) servers are usually identified by port number 80; packets containing traffic destined for a Web server will contain this port ID.
Page 130 Hurricane 9200/S ADSL Ethernet Router User’s Guide The Basic flavor translates the private (LAN-side) IP address to a public (WAN-side) address, like NAPT rules. However, unlike NAPT rules, Basic rules do not also translate the port numbers in the packet header; they are passed through untranslated. Therefore, the Basic rule does not provide the same level of security as the NAPT rule.
Page 131 Chapter 12. Configuring Network Address Translation 5. In the Global Address From and Global Address To fields, type the starting and ending addresses that identify the pool of public IP addresses that the private addresses should be translated to. Or, type the same address in both fields (if you also specified a single address in step 4).
Page 132 Hurricane 9200/S ADSL Ethernet Router User’s Guide 3. Select a protocol to which this rule applies, or choose ANY. This selection specifies which type of Internet communication will be subject to this translation rule. You can select ANY if the rule applies to all data.
Page 133 Chapter 12. Configuring Network Address Translation # ?# Unlike the other NAT flavors, the Bimap flavor performs address translations in both the outgoing and incoming directions. In the incoming direction, when the specified Hurricane 9200/S interface receives a packet with your public IP address as the destination address, this address is translated to the private IP address of a computer on your LAN.
Page 134 Hurricane 9200/S ADSL Ethernet Router User’s Guide @ % # "" " You can create a Pass rule to allow a range of IP addresses to remain untranslated when another rule would otherwise do so. Figure 56. NAT Rule – Add Page (Pass Flavor) The Pass rule must be assigned a rule ID that is a lower number than the ID assigned to the rule it is intended to pass.
