Advanced Setup |
Firewall Select this option can automatically detect and block Denial of Service (DoS) attacks, such as Ping of Death, SYN Flood, Port Scan and Land Attack. |
Routing Select this Option will list the routing table information. You can also Add/Edit/Drop the static route. |
Routing :: Static Route Select this option to set static Routing information. Destination IP Address This parameter specifies the IP network address of the final destination. IP Subnet Mask Enter the subnet mask for this destination. Gateway IP Address Enter the IP address of the gateway. The gateway is an immediate neighbor of your ADSL Router that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your Router; over Internet (WAN), the gateway must be the IP address of one of the remote nodes. Metric Metric represents the "cost" of transmission for routing purposes. IP Routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not to be precise, but it must between 1 and 15. In practice, 2 or 3 is usually a good number. Announced in RIP This parameter determines if the ADSL router will include the route to this remote node in its RIP broadcasts. If set to Yes, the route to this remote node will be propagated to other hosts through RIP broadcasts. If No, this route is kept private and is not included in RIP broadcasts. |
NAT Select this option to setup the NAT (Network Address Translation) function for your ADSL router. Virtual Circuit Enter Virtual Circuit Index that you plan to setup for the NAT function NAT Status This field shows the current status of the NAT function for the current VC. Number of IPs This field is to specify how many IPs are provided by your ISP for current VC. It can be single IP or multiple IPs. Note: for VCs with single IP, they share the same DMZ and Virtual servers; for VCs with multiple IPs, each VC can set DMZ and Virtual servers. Furthermore, for VCs with multiple IPs, they can define the Address Mapping rules; for VCs with single IP, since they have only one IP, there is no need to individually define the Address Mapping rule. |
NAT :: DMZ A DMZ (demilitarized zone) is a host between a private local network and the outside public network. It prevents outside users from getting direct access to a server that has company data. Users of the public network outside the company can access only the DMZ host. DMZ Host IP Address Enter the specified IP Address for DMZ host on the LAN side. |
NAT :: Virtual Server The Virtual Server is the server or server(s) behind NAT (on the LAN), for example, Web server or FTP server, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Rule Index The Virtual server rule index for this VC. You can specify 10 rules in maximum. All the VCs with single IP will use the same Virtual Server rules. Start & End port number Enter the specific Start and End Port number you want to forward. If it is one port only, you can enter the End port number the same as Start port number. For example, you want to set the FTP Virtual server, you can set the start and end port number to 21. Local IP Address Enter the IP Address for the Virtual Server in LAN side. |
NAT :: IP Address Mapping The IP Address Mapping is for those VCs that with multiple IPs. The IP Address Mapping rule is per-VC based. (only for Multiple IPs' VCs). Rule Index The Virtual server rule index for this VC. You can specify 10 rules in maximum. All the VCs with single IP will use the same Virtual Server rules. Rule Type There are four types of one-to-one, Many-to-One, Many-to-Many Overload and Many-to-Many No-overload. Local Start & End IP Enter the local IP Address you plan to mapped to. Local Start IP is the starting local IP address and Local End IP is the ending local IP address. If the rule is for all local IPs, then the Start IP is 0.0.0.0 and the End IP is 255.255.255.255. Public Start & End IP Enter the public IP Address you want to do NAT. Public Start IP is the starting public IP address and Public End IP is the ending public IP address. If you have a dynamic IP, enter 0.0.0.0 as the Public Start IP. |
QoS
QoS (Quality of Service) This option will provide better service of selected network traffic over various technologies. |
QoS::802.1p Select this option to Activate/Deactivated the 802.1p IEEE 802.1p establishes eight levels of priority(0 ~ 7). Although network managers must determine actual mappings, IEEE has made broad recommendations. Seven is the highest priority which is usually assigned to network-critical traffic such as Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) table updates. Five and six are often for delay-sensitive applications such as interactive video and voice. Data classes four through one range from controlled-load applications such as streaming multimedia and business-critical traffic - carrying SAP data, for instance - down to "loss eligible" traffic. Zero is used as a best-effort default priority, invoked automatically when no other value has been set. |
QoS::IP QoS Select this option to Activated/Deactivated the IP QoS on different types(IP ToS and DiffServ). IP QoS function is intended to deliver guaranteed as well as differentiated Internet services by giving network resource and usage control to the Network operator. |
QoS::Applications QoS Select this option to Activated/Deactivated the different application packets prioritized on the queues. |
QoS::VLAN Group QOS
Select this option to Activated/Deactivated the 4094 VID on the 4 different queues. VID(VLAN ID) is the identification of the VLAN, which is basically used by the standard 802.1Q. It has 12 bits and allow the identification of 4096 (2^12) VLANs. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094. |
VLAN Virtual LAN (VLAN) is a group of devices on one or more LANs that are configured so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, it is very flexible for user/host management, bandwidth allocation and resource optimization. 1.Port-Based VLAN: each physical switch port is configured with an access list specifying membership in a set of VLANs. 2.ATM VLAN - using LAN Emulation (LANE) protocol to map Ethernet packets into ATM cells and deliver them to their destination by converting an Ethernet MAC address into an ATM address. The key for the IEEE 802.1Q to perform the above functions is in its tags. 802.1Q-compliant switch ports can be configured to transmit tagged or untagged frames. A tag field containing VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame. If a port has an 802.1Q-compliant device attached (such as another switch), these tagged frames can carry VLAN membership information between switches, thus letting a VLAN span multiple switches. However, it is important to ensure ports with non-802.1Q-compliant devices attached are configured to transmit untagged frames. Many NICs for PCs and printers are not 802.1Q-compliant. If they receive a tagged frame, they will not understand the VLAN tag and will drop the frame. Also, the maximum legal Ethernet frame size for tagged frames was increased in 802.1Q (and its companion, 802.3ac) from 1,518 to 1,522 bytes. This could cause network interface cards and older switches to drop tagged frames as "oversized." |
PVID( Port VLAN ID) Each physical port has a default VID called PVID (Port VID). PVID is assigned to untagged frames or priority tagged frames (frames with null (0) VID) received on this port. |
ADSL The ADSL feature can be selected when you meet the physical connection problem. Please check the proper settings with your Internet service provider. |
ADSL Mode Select the ADSL operation mode which your ADSL connection uses. |
ADSL Type Select the ADSL operation type which your ADSL connection uses. |
