Option Options: VLAN ID Priority Bits 1 Description NAT / Firewall NAT (Network Address Translation allows you to share the public IP address assigned to the WAN (Wide Area Network) interface of your modem with multiple clients on your LAN (Local Area Network). NAT also acts as a basic firewall. The firewall feature protects the PCs on your LAN from malicious attacks from people on the Internet (e.g. DOS attacks).
PPPoE Connection Setup PPP Settings Option Description Username: Enter the username provided by your ISP. Password: Enter the password provided by your ISP. Idle Timeout: Idle timeout means the router will disconnect after being idle for a preset amount of time. The default is 60 seconds. If you set the time to 0, the ADSL connection will remain always connected to the ISP. Keep Alive: If mode is LCP, This is the Keep Alive timer.
Option Description On Demand: If enabled the Idle Timeout field can be modified. On Demand specifies that the modem will connect to the Internet on demand. Default Gateway: Specifies that this connection will be the default gateway for other LAN groups to access the Internet. Enforce MTU: Specifies that the MTU setting will be enforced. Debug: Enable to turn on the debugging mode of your modem. Your ISP may ask you to do this should you be experiencing problems connecting to the Internet.
PVC (Private Virtual Circuit) Settings Option Description VPI: (Virtual Path Identifier) If instructed to change this, type in the VPI value for the initial connection (using PVC 0). Default = 0. VCI: (Virtual Channel Identifier) If instructed to change this, type in the VCI value for the initial connection (using PVC 0). Default = 0. Your modem can support up to 8 PVCs. For example, you could have one PVC (8/35) for your Internet traffic, and another PVC (9/35) for your VoIP traffic.
PPPoA Connection Setup When specifying your connection Type to be PPPoA you are able to change the Encapsulation to either LLC (Logical Link Control) or VC (Virtual Circuit) encapsulation. The default is LLC so do not change this setting unless your ISP instructs you to do so. YML780 Rev1 www.netcomm.com.
Static Connection Setup Option Description Encapsulation: Select the method of encapsulation used by your ISP. The default is LLC, so only change this to VC if your ISP asks you to. IP Address: If your ISP has issued you with a static public IP address, you need to specify it here. (e.g. 210.1.123.123). Mask: The subnet mask specified by your ISP. Default Gateway: The default gateway specified by your ISP. DNS: You have the choice to specify up to three DNS (Domain Name Service) servers.

Logout Click Log Out to logout of the modem’s configuration interface. YML780 Rev1 www.netcomm.com.
Advanced The Advanced menu allows you to configure a number of features of your modem. This section deals with these features. NB1 User Guide 34 YML780 Rev1 www.netcomm.com.
Advanced>UPnP Your modem is Universal Plug ‘n Play Capable, for security this feature is disabled by default. The UPnP architecture is a distributed, open networking architecture that leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices in the home, office, and everywhere in between.
Advanced>SNTP SNTP (Simple Network Time Protocol) allows your modem to update its time automatically using an SNTP server. To enable this feature, click the Enable SNTP tick box. NB1 User Guide 36 YML780 Rev1 www.netcomm.com.
Option Description Primary, Secondary, Tertiary SNTP Servers This allows you to enter three different SNTP server addresses. If one of these servers is unavailable your modem will use an alternative. An example of an NTP server on the Internet is 128.250.36.3. Timeout: The number of seconds your modem will attempt to connect to an SNTP server before trying an alternative server should the server you are trying to connect to be unavailable.
Advanced>SNMP The Simple Network Management Protocol (SNMP) allows a network administrator to monitor a network by retrieving settings on remote network devices. The network administrator typically runs an SNMP management station program such as MIB browser on a local host to obtain information from an SNMP agent such as the router you use now. Option Description Vendor OID: The enterprise OID to which the system belongs to. Enable SNMP Agent: Enabled by default.
Option Description Traps Destination IP: The IP address of the SNMP management device. Trap Community: Used when sending SNMP traps to another device. Trap Version: Version 1 or 2c. Apply: Click Apply to save the changes. YML780 Rev1 www.netcomm.com.
Advanced>IPQoS IP QoS (Quality of Service) allows you to set priorities for traffic travelling through your modem. For example, you may want to prioritize your UDP traffic over your TCP traffic. Typical UDP traffic would be your VoIP (Voice over Internet Protocol) traffic. This section describes how to make use of your modem’s IPQoS feature. The NB1 should have two primary sections for setting up IP QoS services: 1. A QoS setup page to configure the upstream/downstream connection queue priorities, and 2.
Transmit queues associated with LAN connection The high priority queue has strict priority over the medium and low priority queue, and therefore can exhaust all available bandwidth. The web UI will allow the user to select the weights of the medium and low priority queues in increments of 10 percent so that the sum of the weights of the 2 queues is equal to 100 percent.
Traffic Queuing Configuration Based on the TOS (DSCP) marking, the NB1 shall prioritize the traffic servicing on the outgoing interface (facing the Access Network) using a 3-band priority mechanism as described below. Queue Priorities: One Expedited Forwarding (EF) Queue: High Priority queue with non-preemptible service. The EF queue is always scheduled first prior to the medium and low priority queues and runs to completion Two Queues (Medium and Low Priority) with Weighted Round Robin service.
WRR Queue Scheduler for Medium and Low priority queues The L and M weights will be configured from the Web UI as stated above in 1.) Queue Priorities. A service scheduling array will be pre-computed for the Medium and Low priority queues based on the user configurable weights assigned to these queues. Each array slot corresponds to a scheduling cycle.
The four TOS bits (the ‘TOS field’) are defined as: Binary Meaning 1000 Minimize delay (md) 0100 Maximize throughput (mt) 0010 Maximize reliability (mr) 0001 Minimize monetary cost (mmc) 0000 Normal Service TOS Bits Means Linux Priority Queue Priority Band 0x0 0 Normal Service 0 Best Effort 2 0x2 1 Minimize Monetary Cost 1 Filler 2 0x4 2 Maximize Reliability 0 Best Effort 2 0x6 3 mmc+mr 0 Best Effort 2 0x8 4 Maximize Throughput 2 Bulk 1 0xa 5 mmc+mt 2 Bulk
Advanced>Port Forwarding Port Forwarding is necessary because NAT [=Network Address Translation] only forwards traffic from the Internet to the LAN if a specific port mapping exists in the NAT translation table. Because of this, the NAT provides a level of protection for computers that are connected to your LAN. However, this also creates a connectivity problem when you want to make LAN resources available to Internet clients, which you may want to do to play network games or host network applications.
The reason for this is that when using NAT, your publicly accessible IP address will be used by and point to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of unique parameter values for Internet protocols. Port numbers range from 0 to 65535, but only ports numbers 0 to 1023 are reserved for privileged services and are designated as “well-known ports”.
Easy Port Forwarding: Applying Pre-Defined Rules Available pre-defined rules are categorised according to the application type. Click the Radio Button adjacent to the appropriate Category, and then select the required application name. Click on the Add button to move the application into the Applied Rules box. In the example shown on the previous page, ‘Delta Force’ has been selected from the list of Available Rules and is about to be copied to Applied Rules.
DMZ Settings A DMZ (demilitarized zone) is a computer host or small network inserted as ‘neutral territory’ between a private LAN and the Internet. It prevents outside users from getting direct access to LAN computers while still being able to access services hosted on the designated DMZ Computer. When using NAPT to share your internet connection, LAN computers will still be able to access the Internet when the DMZ host is enabled.
Advanced Port Forwarding: Creating Custom Rules Click the Custom Port Forwarding link to setup a custom rule. If there is no pre-defined Port Forwarding Rule for a particular application, a User Rule can be created which defines the required Port(s), Protocol(s) and Internal Port forwarding rules. To create a custom rule you will need to know the specific port number(s) and port type [UDP or TCP] that the application requires. These will be the outside port numbers.
Option Description Source IP Address: The client on the Internet sending the data (e.g. 202.44.55.66). Note, if you do not know the IP address of the client use 0.0.0.0 for any client on the Internet. Source Netmask: The subnet mask of the client connecting to you. Note, if you do not know the Netmask use 0.0.0.0. Destination IP Address: The LAN IP address of the device on your network to which packets of data will be forwarded to (e.g. 192.168.1.2).
Advanced>IP Filters The IP filters page allows you to specify Normal Port Forwards, Block ALL traffic to specific LAN Clients or specify Custom IP filters that will control the flow of data across the router.
Advanced>LAN Clients LAN Client names are a way of applying specific Port-forwarding and Access Control rules to individual computers on the LAN. If DHCP is used, all DHCP clients are automatically assigned and are designated as a LAN client. To add a LAN client, click Advanced>LAN Clients. Option Description Select LAN Group: Select the LAN group you would like to add a LAN client to. Enter IP Address: Enter the IP address of the LAN client to be added. Hostname: Enter the Hostname.
Advanced>Bridge Filters Bridge filtering enables rules to be defined which allow or deny data to pass through the Router based on the source and destination Bridge address and data type of each data frame. To access Bridge Filters Control, click on Advanced>Bridge Filters.
Edit or Delete Bridge Filter Rules To edit an existing Bridge Filter Rule, click the radio button adjacent to the Filter Rule name. The Rule will then appear in the top half of the Bridge Filter control screen where it can be edited. When editing is complete, click ‘Add’ to return the Rule to the list of existing rules. To delete Bridge Filter Rules, click on the ‘Delete’ tick box; multiple deletions can be made by shift-clicking Delete tick boxes; Select All will select every rule.
Advanced>Multicast IGMP [=Internet Group Management Protocol] Multicast enables communication between a single sender and multiple receivers on a network. It is used when data needs to be sent from one to many devices. Typical uses might include the updating of mobile personnel from a home office or the periodic publishing of an online newsletter. Multicasting provides efficiencies which enable it to use less network bandwidth than the sending of the same data by other means [e.g. SMTP].
Advanced>Static Routing If the Router is required to serve more than one network, you will need to set up a Static Route between the networks. Static routing can be used to allow users from one IP domain to access the Internet through the Router in another domain. A Static Route provides the defined pathway that network information must travel to reach the specific host or network which is providing Internet access . To access the Static Routing controls, click on Advanced> Static Routing.
Advanced>Dynamic Routing Dynamic Routing makes use of the RIP Protocol to allow the ADSL Router to automatically adjust to physical changes in the network. The NB1, using the RIP protocol, will determine the network packet route based on the least number of hops between the Source and the Destination. The RIP protocol regularly broadcasts routing information to other Routers on the network and is part of the IP Suite. To access Dynamic Routing click Advanced>Dynamic Routing.
Advanced>Access Control Use Access Control to configure advanced security functions by customising the Modem Firewall. The default ‘Firewall On’ setting blocks all anonymous Internet traffic. Access control enables the user to selectively direct such traffic, for example to a Web Host in the DMZ or to specific ports opened for such applications as Web, Telnet or FTP. CAUTION: This dialog box indicates that you should not disable LAN Web Access or else you might not be able to connect to the device.
