DSL-G604T

Advanced
UPnP UPnP allows automatic discovery and control of services available on the network from other devices without user intervention. Devices that act as servers can advertise their services to clients. Client systems, known as control points, can search for specific services on the network. When they find the devices with the desired services, the control points can retrieve detailed descriptions of the devices and services and interact from that point on.

Virtual Server
The DSL-G604T can be configured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN network. Depending on the requested service (TCP/UDP port number), the DSL-G604T redirects the external service request to the appropriate server within the LAN network.
Rule Name - You can enter a name for the rule.
Private IP - The server computer in the LAN network that will be providing the virtual services.
Protocol - The protocol used for the virtual service.

SNMP SNMP is a popular network monitoring and management protocol.
Filters Filters are used to deny LAN computers from accessing the Internet. The Router can be setup to deny internal computers by their IP addresses. The DSL-G604T can also block users from accessing restricted web sites.

IP Filters-Outbound
Use IP Outbound Filters to deny LAN IP addresses from accessing the Internet. You can deny specific port numbers or all ports for the specific IP address.
Source IP - IP address criteria for the source computer(s) from which the packet originates.
Destination IP - IP address rule criteria for the destination computer(s) (i.e., the IP address of the computer to which the packet is being sent).
Source Port - Port number criteria for the computer(s) from which the packet originates. This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option. (safe port- any port number above 1024 is considered as safe port)
Destination Port - Port number criteria for the computer(s) (i.e., the port number of the type of computer to which the packet is being sent). This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option.
Protocol - drop down menu allows you to select the transport protocol for this access policy. Now "TCP", "UDP" or both of them are provided.
Action - menu helps in defining this policy as Allow or Deny type policy. Allow type policies allow the traffic matched by the policy selectors to pass through, where as Deny type policy blocks that traffic.

IP Filters-Inbound
Use IP Inbound Filters to deny WAN IP addresses from accessing the internal network. You can deny specific port numbers or all ports for the specific IP address.
Source IP - IP address criteria for the source computer(s) from which the packet originates.
Destination IP - IP address rule criteria for the destination computer(s) (i.e., the IP address of the computer to which the packet is being sent).
Source Port - Port number criteria for the computer(s) from which the packet originates. This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option.
Destination Port - Port number criteria for the computer(s) (i.e., the port number of the type of computer to which the packet is being sent). This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Source IP Address for the selection option.
Protocol - drop down menu allows you to select the transport protocol for this access policy. Now "TCP", "UDP" or both of them are provided.
Action - menu helps in defining this policy as Allow or Deny type policy. Allow type policies allow the traffic matched by the policy selectors to pass through, where as Deny type policy blocks that traffic.

Bridge Filters Bridge filter enables users to specify the desired source MAC address, destination MAC address and/or protocol type to deny or allow.
LAN Client Lan clients enables users to specify the desired lan clients' IP for selectabled by setting the rules of Virtual Server.

Routing
The Route Table page displays routing table and allows the user to manually enter the routing entry. The routing table will display the routing status of Destination, Netmask, Gateway, and Interface. The interface br0 means the bridge interface; lo0 means the loopback interface; and ppp1 means the PPP interface. The Gateway is the learned Gateway.

Destination - This field allows the user to enter the remote network or host IP address for the static routing.
Netmask - This field allows the user to enter the Subnet Mask for the static routing.

- Only one of the following items can be selected at a time.
Gateway - This field allows the user to enter the IP address of the gateway device that allows the router to contact the remote network or the host for Specified IP or select an Interface for the Gateway.
Connection - Select a PVC setting for routing information.

DMZ If you have a client PC that cannot run Internet applications properly from behind the DSL-G604T, then you can set the client up to unrestricted Internet access. Enter the IP address of a DMZ host. Adding a client to the DMZ (Demilitarized Zone) may expose your local network to a variety of security risks, so only use this option as a last resort.

Firewall
Firewall Rules is an advance feature used to deny or allow traffic from passing through the DSL-G604T. It works in the same way as IP Filters with additional settings.
DoS Protecction - Click the Enable radio button to use the following denial of service protection:(1)SYN DoS(2)ICMP DoS
Port Scan Protection - Enable this firewall can protect your machine from being port scanned.
Service Filtering - Select to block the desired services.

RIP
RIP is an internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP's location, or on remote networks connected to your network via the ADSL line.
RIP - Enable/Disable the RIP function.
Protocol - RIP V1/V2/V1 Compatible
Direction - In/Out/Both

PPP Configuration
If your WAN connection is set up for PPPoE, there will be a Connect/Disconnection button. Use Disconnect to drop the PPPoE connection and use Connect to establish the PPPoE connection.
Always On - Once the device is power-on, it would initiate the PPP connection automatically.
Connection on Demand - The device would initiate the PPP connection after there is a outbound packet. The Router would close the PPP connection while the inactivity idle time longer than the setting value.
Manual - Use the Connect/Disconnect to initiate/close the PPP connection manually.

ADSL Configuration The ADSL Configuration page allows the user to set the configuration for ADSL protocols.

ATM VCC
This page is used to view and configure ATM VCs.
VPI - If instructed to change this, type in the VPI value for the initial connection (using PVC 0). Default= 8.
VCI - If instructed to change this, type in the VCI value for the initial connection (using PVC 0). Default= 35.
Virtual Circuit - The Virtual Circuit over which this PPP data is sent. The VC identifies the physical path the data takes to reach your ISP.
WAN Setting - Choose the WAN setting among Dynamic IP/Static IP/PPPoE/PPPoA/Bridge Mode
Connection Type - Choose 1483 Bridged IP LLC or 1483 Bridged IP VC-Mux,PPPOA,PPPOE,1483 Routed IP LLC,1483 Routed IP VC from the pull-down menu.

Configure Wireless Management Access List -This function allow administrator to have access control by enter MAC address of client stations. Associated Stations -station status. Multiple SSID - Assign different SSID.

Wireless Performance
Select to configure advanced wireless parameters.
Beacon Interval -The Beacon Interval value indicates the frequency interval of the beacon. Enter a value between 20 and 1000. A beacon is a packet broadcast by the Router to synchronize the wireless network. The default value is 100.
DTIM Interval -This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Access Point Clients hear the beacons and awaken to receive the broadcast and multicast messages.
Hidden SSID - Hide ESSID and Access Control further strengthen the safety of the wireless transmission.
RTS Threshold: This value should remain at its default setting of 2346. Should you encounter inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission.
Fragmentation Threshold: This value specifies the maximum size for a packet before data is fragmented into multiple packets. It should remain at its default setting of 2346. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor modifications of this value are recommended.
