1 21. Multiple WAN Vigor 3300Bplus has three WAN interfaces, while Vigor 3300 and Vigor 3300V both have four WAN interfaces. With the Load Balance feature, you can use multiple WAN links simultaneously. So as to share the bandwidth and increase the connection speed. A specific IP with specific Ports and Protocols uses a dedicated WAN (Load Balance Policy). A single WAN interface uses multiple static IP addresses (IP Alias + Address Mapping). Set packets which are coming to a specific WAN port to be passed to a specific port of internal computers (Port Redirection). Set any traffic which are sent to a specific WAN to be passed to a specific internal computer (DMZ Host). We will divide a network into various subnets. Each example will be explained based on this division. Based on the LAN Setup, Vigor 3300 uses the network: X. The internal network are planned and designed based on different departments and usages. In addition, 63 IP addresses are reserved for DHCP IP range, which are assigned by the built-in DHCP Server of Vigor Vigor3300 Series Application Note V

2 Table Subnets of the company IP Address Subnet Mask User IP Number Network (Router) FTP and Web Server Mail Server PPTP Server IPSEC Server ~ Administrator ~ MIS ~ Accounting Department ~ Business Department ~ RD Department ~ DHCP Broadcast Then, you can apply different restrictions and applications according to the planning table, which can facilitate deployment of Load Balance Policy, Address Mapping, Firewall, QoS and VPN. All the computers should be assigned fixed IP addresses except those within the subnet which are reserved for DHCP. The IP Address and Subnet Mask listed in the Table 22-1 above are what you should type in the Web configuration of Vigor Actually computers are still configured with IP Address X and Subnet Mask Suppose the network address is X. The factory default of the IP address of Vigor 3300 is Please refer to the LAN Setup for details on changing the network. The following modifications are based on the LAN Setup. 130 Vigor3300 Series Application Note V2.2

3 21.1 LAN Configuration Example 1. Please enter the Network LAN page, and click the tab 1st DHCP Server. Please refer to Figure Figure st DHCP server of LAN 2. Change the IP range of DHCP assignment, from to Then click the Apply button to go on. Please refer to Figure Figure IP range 3. Afterwards the router will switch to the reboot page. After the router reboots, Vigor 3300 will assign a new IP addresses starting from For relevant settings, please refer to Step 4 ~ Step 9 in the LAN Setup. Vigor3300 Series Application Note V

4 21.2 Fixed IP Configuration Example Each computer or server must be assigned a specific fixed IP address except those in the field of DHCP. 1. Enter Start\Settings\Control Panel. Please refer to Figure Figure The location of control panel 2. Open Network Connections. Please refer to Figure Figure Network connections 132 Vigor3300 Series Application Note V2.2

5 3. Open the NIC which is used to connect to Vigor Please refer to Figure Figure Open the NIC 4. Click the Properties button. Please refer to Figure Figure Click properties Vigor3300 Series Application Note V

6 5. Select Internet Protocol(TCP/IP),and then click the Properties button. Please refer to Figure Figure Click properties 6. Suppose on this computer are running a FTP Server and a Web Server, as the Figure 22-8 shown below, the IP Address and Subnet Mask should be and The Default Gateway is (Router), and the IP address of the DNS Server generally is Figure TCP/IP properties 134 Vigor3300 Series Application Note V2.2

7 7. Check the box Show icon in notification area when connected, and then click the OK button. Please refer to Figure Figure Check the box 8. Check the icon in the system tray at the right bottom of the window on your desktop. Please refer to Figure Figure Check the icon A red cross on the icon means the network link is down or the connection to Vigor 3300 is interrupted. Please check the network cable and make sure that the LAN LED of Vigor 3300 is OK. Please refer to Figure Figure Check the icon Vigor3300 Series Application Note V

8 9. Enter Start\Programs\Accessories\Command Prompt, and type ipconfig /all to confirm if the IP address is fixed. Try to ping After receiving the response, the configuration is completed. Please refer to Figure Figure IP configuration 136 Vigor3300 Series Application Note V2.2
