The Quick Setup allows the user to configure the ADSL 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-5611T ADSL 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-5611T is to run the PPPoE client. The CT-5611T 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-5611T also supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client fro 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. For instance, at initial setup, the default network operating mode is Bridge. The main panel will not show the NAPT and Firewall menu.

radio button and click Next. The following screen appears:
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.
Disconnect if no activity The CT-5611 can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand check box. When the checkbox is ticked, you need to enter the inactivity timeout period. The timeout period ranges from 1 minute to 4320 minutes.
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.

Enable NAT checkbox

If the LAN is configured with a private IP address, the user should select this checkbox. The NAT submenu on the left side main panel will be displayed 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. When the system comes back after reboot, the NAT submenu will not be displayed on the left main panel. Enable Firewall The Internet has made large amounts of information available to the average computer user at home, in business and in education. For many people, having access to this information is no longer just an advantage, it is essential. Yet connecting a private network to the Internet can expose critical or confidential data to malicious attack from anywhere in the world. Users who connect their computers to the Internet must be aware of these dangers, their implications and how to protect their data and their critical systems. Firewalls can protect both individual computers and corporate networks from hostile intrusion from the Internet, but must be understood to be used correctly.

By default all incoming IP traffic from WAN is Blocked, if the Firewall is Enabled. By setting up one or more filters, particular packet types coming from the WAN can be Accepted. Filter Name: User defined Filter Name. Protocol: Can take on any values from: TCP/UDP, TCP, UDP or ICMP Source IP Address/Source Subnet Mask: Packets with the particular "Source IP Address/Source Subnet Mask" combination will be accepted. Source Port: This can take on either a single port number or a range of port numbers. Packets having a source port equal to this value or falling within the range of port numbers(portX : portY) will be accepted. Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be accepted. Destination Port: This can take on either a single port number or a range of port numbers. Packets having a destination port equal to this value or falling within the range of port numbers(portX : portY) will be accepted.
The WAN interface on which these rules apply needs to be selected by the user. Examples: 1. Filter Name Protocol Source Address Source Subnet Mask Source Port Dest. Address Dest. Sub. Mask Dest. Port : In_Filter1 : TCP : 210.168.219.45 : 255.255.0.0 : 80 :NA : NA : NA
Selected WAN interface: mer_0_35/nas_0_35 This filter will ACCEPT all TCP packets coming from WAN interface mer_0_35/nas_0_35 with IP Address/Sub. Mask 210.168.219.45/16 having a source port of 80 irrespective of the destination. All other incoming packets on this interface are DROPPED. 2. Filter Name Protocol Source Address Source Subnet Mask Source Port Dest. Address Dest. Sub. Mask Dest. Port : In_Filter2 : UDP : 210.168.219.45 : 255.255.0.0 : 5060:6060 :192.168.1.45 : 255.255.255.0 : 6060:7070
This rule will ACCEPT all UDP packets coming from WAN interface mer_0_35/nas_0_35 with IP Address/Sub.Mask 210.168.219.45/16 and a source port in the range of 5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range of 6060 to 7070. All other incoming packets on this interface are DROPPED. MAC Layer Filtering: These rules help in the filtering of traffic at the Layer 2. MAC Filtering is only effective on ATM PVCs configured in Bridge mode. After a Bridge mode PVC is created, navigate to Advanced Setup -> Security -> MAC Filtering web page. Global Policy: When set to Forwarded the default filter behavior is to Forward all MAC layer frames except those explicitly stated in the rules. Setting it to Blocked changes the default filter behavior to Drop all MAC layer frames except those explicitly stated in the rules. To setup a rule: Protocol Type: Can be either PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI, IGMP. Destination MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this particular destination address will be Forwarded/Dropped depending on whether the Global Policy is Blocked/Forwarded.

Source MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this particular source address will be Forwarded/Dropped depending on whether the Global Policy is Blocked/Forwarded. Frame Direction: LAN <=> WAN --> All Frames coming/going to/from LAN or to/from WAN. WAN => LAN --> All Frames coming from WAN destined to LAN. LAN => WAN --> All Frames coming from LAN destined to WAN User needs to select the interface on which this rule is applied. Examples: 1. Global Policy: Forwarded Protocol Type: PPPoE Dest. MAC Addr: 00:12:34:56:78 Source MAC Addr: NA Frame Direction: LAN => WAN WAN Interface Selected: br_0_34/nas_0_34 Addition of this rule drops all PPPoE frames going from LAN-side to WAN-side with a Dest. MAC Addr. of 00:12:34:56:78 irrespective of its Source MAC Addr. on the br_0_34 WAN interface. All other frames on this interface are forwarded. 2. Global Policy: Blocked Protocol Type: PPPoE Dest. MAC Addr: 00:12:34:56:78:90 Source MAC Addr: 00:34:12:78:90:56 Frame Direction: WAN => LAN WAN Interface Selected: br_0_34/nas_0_34 Addition of this rule forwards all PPPoE frames going from WAN-side to LAN-side with a Dest. MAC Addr. of 00:12:34:56:78 and Source MAC Addr. of 00:34:12:78:90:56 on the br_0_34 WAN interface. All other frames on this interface are dropped.
