QoS (Quality of Service) QoS function helps you to control your network traffic for each application from LAN (Ethernet and/or Wireless) to WAN (Internet). It facilitates you to control the different quality and speed of through put for each application when the system is running with full loading of upstream. Here are items within the QoS section: Prioritization and Outbound / Inbound IP Throttling (bandwidth management).
MICHELANGELO SHDSL VPN Firewall Bridge/Router DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP Marking allows users to assign specific application traffic to be executed in priority by the next Router based on the DSCP value. See Table 4. The DSCP Mapping Table: Note: To be sure the router(s) in the backbones network have the capability in executing and checking the DSCP through-out the QoS network.
Outbound IP Throttling (LAN to WAN) IP Throttling allows you to limit the speed of IP traffic. The value entered will limit the speed of the application that you set to the specified value’s multiple of 32kbps. Click Clear You can click Clear to delete the existing Application.

MICHELANGELO SHDSL VPN Firewall Bridge/Router Mission-critical application Mostly the VPN connection is mission-critical application for doing data exchange between head and branch office. The mission-critical application must be sent out smoothly without any dropping. Set priority as high level for preventing any other applications to saturate the bandwidth. Voice application Voice is latency-sensitive application.
Sometime your customers or friends may upload their files to your FTP server and that will saturate your downstream bandwidth. The settings below help you to limit bandwidth for the restricted application.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Virtual Server (“Port Forwarding”) In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.
Add Virtual Server Because NAT can act as a “natural” Internet firewall, your router protects your network from being accessed by outside users when using NAT, as all incoming connection attempts will point to your router unless you specifically create Virtual Server entries to forward those ports to a PC on your network. When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server, Email server or game server, the router can act as a “virtual server”.
MICHELANGELO SHDSL VPN Firewall Bridge/Router If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from you (Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number 80 has already been predefined, next to the Application click Helper. A list of predefined rules window will pop and select HTTP_Sever.
Edit DMZ Host The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP address as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms then passed to the DMZ host, when a packet received does not use a port number used by any other Virtual Server entries. Cautious: This Local computer exposing to the Internet may face varies of security risks. § Disabled: As set in default setting, it disables the DMZ function.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Edit One-to-One NAT (Network Address Translation) One-to-One NAT maps a specific private/local IP address to a global/public IP address. If you have multiple public/WAN IP addresses from you ISP, you are eligible for One-to-One NAT to utilize these IP addresses. NAT Type: Select desired NAT type. As set in default setting, it disables the One-to-One NAT function. Global IP Address: § Subnet: The subnet of the public/WAN IP address given by your ISP.
Time Schedule: A self-defined time period to enable your virtual server. You may specify a time schedule or Always on for the usage of this Virtual Server Entry. For setup and detail, refer to Time Schedule section Application: Users-defined description to identify this entry or click rules. to select existing predefined : 20 predefined rules are available. Click the Radio button to select the rule; Application, Protocol and External/Redirect Ports will be filled after the selection.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Example: List of some well-known and registered port numbers. 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” (Please refer to Table 5). The registered ports are numbered from 1024 through 49151.
Time Schedule The Time Schedule supports up to 16 time slots which helps you to manage your Internet connection. In each time profile, you may schedule specific day(s) i.e. Monday through Sunday to restrict or allowing the usage of the Internet by users or applications. This Time Schedule correlates closely with router’s time, since router does not have a real time clock on board; it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server from the Internet.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Configuration of Time Schedule Edit a Time Slot 1. Choose any Time Slot (ID 1 to ID 16) to edit, click Edit. Click Edit Note: Watch it carefully, the days you have selected will present in capital letter. Lower case letter shows the day(s) is not selected, and no rule will apply on this day(s). 2. A detailed setting of this Time Slot will be shown. ID: This is the index of the time slot. Name: A user-define description to identify this time portfolio.
Advanced Configuration options within the Advanced section are for users who wish to take advantage of the more advanced features of the router. Users who do not understand the features should not attempt to reconfigure their router, unless advised to do so by support staff. Here are items within the A d v a n c e d section: Static Route, Dynamic DNS, Check Email, Device Management, IGMP and VLAN Bridge. Static Route Click on Routing Table and then choose Create Route add a routing table.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Dynamic DNS The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your SHDSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time.
Check Email This function allows you to have the router check your POP3 mailbox for new Email messages. The Mail LED on your router will light when it detects new messages waiting for download. You may also view the status of this function using the Status – Email Checking section of the web interface, which also provides details on the number of new messages waiting. See the Status section of this manual for more information. § Disable: Check to disable the router’s Email checking function.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Device Management The Device Management advanced configuration settings allow you to control your router’s security options and device monitoring features. Embedded Web Server ( 2 Management IP accounts) HTTP Port: This is the port number the router’s embedded web server (for web-based configuration) will use. The default value is the standard HTTP port, 80.
Universal Plug and Play (UPnP) UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and data transfer between devices. UPnP offers many advantages for users running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by letting the application control the required settings, removing the need for the user to control advanced configuration of their device.

IGMP IGMP, known as Internet Group Management Protocol, is used to management hosts from multicast group. IGMP Forwarding: Accepting multicast packet. Default is set to Enable. IGMP Snooping: Allowing switched Ethernet to check and make correct forwarding decisions. Default is set to Disable. VLAN Bridge This section allows you to create VLAN group and specify the member. Edit: Edit your member ports in selected VLAN group. Create VLAN: To create another VLAN group.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Step 1: Setup Member Ports Go to Configuration ‡ LAN ‡ Bridge Interface. You can setup member ports for each VLAN group under Bridge Interface section. From the example, two VLAN groups need to be created. Ethernet: P1 (Port 1) Ethernet1: P2, P3 and P4 (Port 2, 3, 4) Please uncheck P2, P3, P4 from Ethernet VLAN Port first. Note: You should setup each VLAN group with caution. Each Bridge Interface is arranged in this order.
From the example, PVC 0/33 to 0/39 is assigned for video using 1483 Bridged mode. Check RFC 1483 Bridged and click Next to continue the setup. Spaces next to VPI and VCI, type 0 and 33 in respectively. Select appropriate ATM Class, Encapsulation Method, Acceptable Frame Type, Filter Type and PVID for Untagged Frames. VPI and VCI: Enter the information provided by your ISP. ATM Class: The Quality of Service for ATM layer. Encapsulation method: Select the encapsulation format, this is provided by your ISP.
MICHELANGELO SHDSL VPN Firewall Bridge/Router Step 3: Setup VLAN Service Go to Configuration ‡ Advanced ‡ VLAN Bridge DefaultVlan lists all member ports. It is necessary to group specific member ports for each VLAN. From the example, two VLAN groups are requested: Data and Video. To create another VLAN group for Video by clicking Create VLAN. Given a name and ID (PVID) to identify the Video group and the valid value range for PVID is 1 ~ 4094.
Mapping the VLAN Bridge with Bridge Interface created in Step1, you will see the conformable relationship in these two screenshots. Step 4: IGMP Snooping Enable Go Configuration ‡ Advanced ‡ IGMP. IGMP Snooping must be enabled in order to allow video stream forwarding correctly. Save Configuration to Flash After changing the router’s configuration settings, you must save all of the configuration parameters to FLASH to avoid them being lost after turning off or resetting your router.
