Chapter 5 Quick Setup

The Quick Setup allows the user to configure the A/VDSL router for DSL connectivity and Internet access. It also guides the user though the WAN network setup first and then the LAN interface setup. You can either manually customize the router or follow the online instruction to set up the router. The CT-5372E A/VDSL router supports the following five network operating modes over an ATM PVC WAN interface. PPP over Ethernet (PPPoE) PPP over ATM (PPPoA) MAC Encapsulated Routing (MER) IP over ATM (IPoA) Bridging The following configuration considerations apply: The WAN network operating mode operation depends on the service providers configuration on the Central Office side and Broadband Access Server for the PVC If the service provider provides PPPoE service, then the connection selection depends on whether the LAN-side device (typically a PC) is running a PPPoE client or whether the CT-5372E is to run the PPPoE client. The CT-5372E can support both cases simultaneously. If some or none of the LAN-side devices do not run PPPoE client, then select PPPoE. If every LAN-side device is running a PPPoE client, then select Bridge in PPPoE mode. CT-5372E also supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client for non-PPPoE LAN devices. NAPT and firewall are always enabled when PPPoE mode is selected, but they can be enabled or disabled by the user when MER or IPoA is selected, NAPT and firewall are always disabled when Bridge mode is selected. Depending on the network operating mode, and whether NAPT and firewall are enabled or disabled, the main panel will display or hide the NAPT/Firewall menu. Bridge. For instance, at initial setup, the default network operating mode is The main panel will not show the NAPT and Firewall menu.

PPP IP Extension The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specially requires this setup, do not select it. The PPP IP Extension supports the following conditions: Allows only one PC on the LAN The public IP address assigned by the remote side using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PCs LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the ADSL router has a single IP address to assign to a LAN device. NAPT and firewall are disabled when this option is selected. The ADSL router becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address. The ADSL router extends the IP subnet at the remote service provider to the 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 routers 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 Enable the PPPoE debug mode. The system will put more PPP connection information in System Log. But this is for debug, please don't enable in normal usage. 2. Click Next to display the following screen.

Please refer to Appendix A for an Example.

6.10 Port Mapping

Port Mapping supports multiple port to PVC and bridging groups. Each group will perform as an independent network. To support this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button will remove the grouping and add the ungrouped interfaces to the Default group. As shown below, when you tick the Enable virtual ports on, all of the LAN interfaces will be grouped together as a default.
To add a port mapping group, simply click the Add button.
To create a group from the list, first enter the group name and then select from the available interfaces on the list. Automatically Add Clients With the Following DHCP Vendor IDs: Add support to automatically map LAN interfaces including Wireless and USB to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when PortMapping is enabled. In this example there are 4 PVCs (0/33, 0/36, 0/37, 0/38). 0/33 is for PPPoE and the others are for IP setup-box (video). The Lan interfaces are ETH1, ETH2, ETH3, ETH4, Wireless and USB. Port mapping configuration are: 1. Default : ENET1, ENET2, ENET3, ENET4, Wireless, Wireless_Guest and USB. 2. Video: nas_0_36, nas_0_37 and nas_0_38. The DHCP vendor ID is "Video".

Guest SSID

The BSSID is a 48bit identity used to identify a particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Medium Access Control) address of the AP (Access Point) and in Independent BSS or ad hoc networks, the BSSID is generated randomly.
Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to When data encryption is enabled, protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic. secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers. 802.11 supports two subtypes of network authentication services: open system and shared key. Under open system authentication, any wireless station can request The system that needs to authenticate with another wireless The receiving station then sends back a frame that indicates authentication. sending station.
station sends an authentication management frame that contains the identity of the whether it recognizes the identity of the sending station. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from 802.11 wireless network communications channel. The following screen appears when Security is selected. The Security page allows you to configure security features of the wireless LAN interface. You can set the network authentication method, selecting data encryption, specify whether a network key is required to authenticate to this wireless network and specify the encryption strength. Click Apply to configure the wireless security options.

DTIM Interval

Delivery Traffic Indication Message (DTIM), also known as Beacon Rate. The entry range is a value between 1 and 65535. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the The default is 1. Each broadcast and multicast messages.

Beacon Interval

The amount of time between beacon transmissions.
beacon transmission identifies the presence of an access point. By default, radio NICs passively scan all RF channels and listen for beacons coming from access points to find a suitable access point. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). The entered value is represented in ms. Default is 100. Acceptable entry range is 1 to 0xffff (65535) Xpress 54g
Xpress Technology is compliant with draft specifications of two planned wireless industry standards. Set the mode to 54g Auto for the widest compatibility. Select the mode to 54g Performance for the fastest performance among 54g certified equipment. Set the mode to 54g LRS if you are experiencing difficulty with legacy 802.11b equipment.
