Chapter 3 Web User Interface This section describes how to access the device via the web user interface (WUI) using an Internet browser such as Internet Explorer (version 5.0 and later). 3.1 Default Settings The following are the default settings for the device: • • • LAN IP address: 192.168.1.1 / Subnet mask: 255.255.255.
STATIC IP Mode To configure the device manually, your PC must have a static IP address within the 192.168.1.x subnet. Follow the steps below to configure your PC IP address to use subnet 192.168.1.x. The following assumes you are running Windows XP. STEP 1: From the Network Connections window, open Local Area Connection (You may also access this screen by double-clicking the Local Area Connection icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button. The screen should now display as below. Change the IP address to the domain of 192.168.1.x (1
Click OK to continue. NOTE: The login password can be changed later (see 8.6.3 Passwords) STEP 3: After successfully logging in for the first time, you will reach this screen. NOTE1: If a PVC connection already exists then this Quick Setup screen will be bypassed and the Device Info – Summary screen will display instead. NOTE2: The selections available on the main menu (onscreen at left) are based upon the configured connection and user account privileges.
Chapter 4 Quick Setup The function allows the user to configure the ADSL router for DSL connectivity and Internet access. It guides the user though the WAN network setup first and then the LAN interface setup. The user can either manually customize the router or follow the auto quick setup procedure.
Step 2: Click Next to start the setup process. Follow the online instructions to complete the setting. This procedure will skip some advanced setup procedures (such as PVC index and encapsulation selection). Step 3: After the settings are complete, you can use the ADSL service. 4.2 Manual Quick Setup STEP 1: Click Quick Setup and un-tick the DSL Auto-connect checkbox to enable manual configuration of the connection type. Un-tick this checkbox to enable manual setup and display the following screen.
STEP 4: Choosing different connection types pops up different encapsulation. Enter appropriate settings as requested by your service provider. The following descriptions state each connection type setup separately. Select Enable 802.1q (by ticking the box) if required, and input a number for the VLAN ID. Click on Next to go to next step. 4.2.1 PPP over ATM (PPPoA) and PPP over Ethernet (PPPoE) Step 1: Select the PPP over ATM (PPPoA) or PPP over Ethernet (PPPoE) radio button and click Next.
PPP Username/PPP Password The PPP Username and the PPP password requirement are dependent on the particular requirements of the ISP or the ADSL service provider. The WEB user interface allows a maximum of 256 characters in the PPP user name and a maximum of 32 characters in PPP password. Authentication Method Choose from AUTO, PAP, CHAP and MSCHAP. Dial on Demand The CT-5611TC can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand check box.
• LAN PC. That is, the PC becomes a host belonging to the same IP subnet. The ADSL router bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the router’s LAN IP address. Use Static IP Address Unless your service provider specially requires this setup, do not select it. If selected, enter your static IP address. Enable PPP Debug Mode Tick the checkbox to enable this function. Step 2: Click Next to display the screen below.
To configure a secondary IP address for the LAN port, click the checkbox below. Step 4: Click Next to display the WAN Setup-Summary screen that presents the entire configuration summary. Click Save/Reboot if the settings are correct. Click Back if you wish to modify the settings.
Step 5: After clicking Save/Reboot, the router will save the configuration to the flash memory and then reboot. The Web UI will not respond until the system is brought up again. After the system is up, the Web UI will refresh to the Device Info screen automatically. The CT-5611TC is ready for operation and the LEDs display as described in the LED description tables. 4.2.2 MAC Encapsulation Routing (MER) Step 1: Enter the WAN IP settings as directed by your ISP.
NOTE: The DHCP Client can be enabled for PVC in MER mode if Obtain an IP address automatically is chosen. Changing the default gateway or the DNS effects the whole system. Configuring them with static values will disable the automatic assignment from DHCP or other WAN connection. If you configure static default gateway over this PVC in MER mode, you must enter the IP address of the remote gateway in the Use IP address field. Step 2: Click Next to display the following screen.
Step 3: Upon completion click Next. The following screen appears. The Device Setup screen allows the user to configure the LAN interface IP address and DHCP server. If the user would like this ADSL router to assign dynamic IP addresses, DNS server and default gateway to other LAN devices, select the radio box Enable DHCP server on the LAN to enter the starting IP address and end IP address and DHCP lease time.
Step 5: After clicking Save/Reboot, the router will save the configuration to the flash memory, and reboot. The Web UI will not respond until the system is brought up again. After the system is up, the Web UI will refresh to the Device Info screen automatically. The CT-5611TC is ready for operation and the LEDs display as described in the LED description tables. 4.2.3 IP Over ATM Step 1: Enter the WAN IP settings as directed by your ISP. NOTE: DHCP is not supported over IPoA.
Step 2: Click Next. The following screen appears. Enable NAT checkbox If the LAN is configured with a private IP address, the user should select this checkbox. The NAT submenu will be displayed on the advanced setup menu after reboot. The user can then configure NAT-related features after the system comes up. If a private IP address is not used on the LAN side (i.e. the LAN side is using a public IP), this checkbox should be de-selected.
NOTE : Enable DHCP Server Relay will not display if NAT is enabled. The user must configure the IP Address and the Subnet Mask. To use the DHCP service on the LAN, select the Enable DHCP server checkbox, and enter the Start IP addresses, the End IP address and DHCP lease time. This configures the router to automatically assign IP addresses, default gateway address and DNS server addresses to each of your PCs. Select Enable DHCP Server Relay (if required), and enter the DHCP Server IP Address.
Step 5: After clicking Save/Reboot, the router will save the configuration to the flash memory, and reboot. The Web UI will not respond until the system is brought up again. After the system is up, the Web UI will refresh to the Device Info screen automatically. The CT-5611TC is ready for operation and the LEDs display as described in the LED description tables. 4.2.4 Bridging Step 1: Tick the checkbox to Enable Bridge Service and enter a Service Name. Step 2: Click the Next button to continue.

Although Microsoft Windows does not have a ssh client, there is a public domain one called “putty” that can be downloaded from here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html To access the ssh client you must first enable SSH access for LAN or WAN from the Management Æ Access Control Æ Services menu in the web user interface.
Appendix D: Security Stateful Packet Inspection Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header. Denial of Service Attack Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have.
