Chapter 5 Quick Setup

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-5361T 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-5361T is to run the PPPoE client. 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-5361T also supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client fro non-PPPoE LAN devices. NAT 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, NAT 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. The CT-5361T can

Encapsulation Mode Choosing different connection types provides different encapsulation modes. PPPoA- VC/MUX, LLC/ENCAPSULATION PPPoE- LLC/SNAP BRIDGING, VC/MUX MER- LLC/SNAP-BRIDGING, VC/MUX IPoA- LLC/SNAP-ROUTING, VC MUX Bridging- LLC/SNAP-BRIDGING, VC/MUX Disconnect if no activity The CT-5361T 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. minute to 4320 minutes. The timeout period ranges from 1
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.

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. 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, USB Wireless and Wireless_Guest. Port mapping configuration are: 1. Default: ETH1, ETH2, ETH3, ETH4, USB Wireless and Wireless_Guest.
2. Video: nas_0_36, nas_0_37 and nas_0_38. The DHCP vendor ID is "Video". The CPE's DHCP server is running on "Default". And ISP's DHCP server is running on PVC 0/36. It is for setup-box use only. In the LAN side, PC can get IP address from CPE's DHCP server and access Internet via PPPoE (0/33). If the setup-box was connected with interface "ETH1" and send a DHCP request with vendor id "Video", CPE's DHCP server will forward this request to ISP's DHCP server. And CPE will change the port mapping configuration automatically. The port mapping configuration will become: 1. Default: ETH2, ETH3, ETH4, USB Wireless and Wireless_Guest. 2. Video: nas_0_36, nas_0_37, nas_0_38 and ETH1.

Appendix A: Firewall

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. Various DoS attacks the device can withstand are: ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf Attack and Tear Drop. TCP/IP/Port/Interface filtering rules These rules help in the filtering of traffic at the Network layer i.e. Layer 3. When a Routing interface is created "Enable Firewall" must be checked. Navigate to Advanced Setup -> Security -> IP Filtering, web page. Outgoing IP Filtering: Helps in setting rules to DROP packets from the LAN interface. By default if Firewall is Enabled all IP traffic from LAN is allowed. By setting up one or more filters, particular packet types coming from the LAN can be dropped. 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 IP Address/Source Subnet Mask" combination will be dropped. 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 dropped. "Source

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.

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 PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI or 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: 00:12:34:56:78:90 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.
