LAN
You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP
service to manage the IP settings for their private network. The IP address of the Router is the base address used for DHCP. In order to use the
Router for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the Router. The IP addresses
available in the DHCP IP address pool will change automatically if you change the IP address of the Router.
To access the Local Area Network (LAN) Setup window, click the LAN button in the Advanced Setup directory.
This window allows you to set up a LAN interface. When you are finished,
click either the Save or Save/Reboot button.

D-Link DSL-2650U User Manual 51
Port Triggering
Some applications require that the remote parties open specific ports in
the Router’s firewall for access. Port Trigger dynamically opens the Open
Ports in the firewall when an application on the LAN initiates a TCP/UDP
connection to a remote party using Trigger Ports. The Router allows the
remote party form the WAN side to establish new connections back to the
application on the LAN side using the Open Ports.
Applications such as games, video conferencing, and other remote
access applications require that specific ports in the Router’s firewall be
opened for access by applications.
Click the Add button to configure port triggering.

configuration. The new Application Rule will appear in the Port Triggering
table.
Section 3 – Configuration
D-Link DSL-2650U User Manual 53
DMZ Host
Since some applications are not compatible with NAT, the Router supports
use of a DMZ IP address for a single host on the LAN. This IP address is
not protected by NAT and will therefore be visible to agents on the Internet
with the right type of software. Keep in mind that any client PC in the DMZ
will be exposed to various types of security risks. If you use the DMZ, take
measures (such as client-based virus protection) to protect the remaining
client PCs on your LAN from possible contamination through the DMZ.
To designate a DMZ IP address, type in the IP Address of the server or
device on your LAN, and click the Save/Apply button.
Security
To access the Security window, click the Security button in the Advanced Setup directory. The Security button appears after configuring WAN
interface.
IP Filtering
The IP Filtering button appears when configuring WAN interface in PPPoA, PPPoE, MER or IPoA.
IP Filtering - Outgoing
This window allows you to create a filter rule to block outgoing IP traffic by
specifying a filter name and at least one condition on this window. All of
the specified conditions in this filter rule must be satisfied for the rule to
take effect. Filters are used to allow or deny LAN or WAN users from
accessing the Internet or your internal network.
If you are setting up the outgoing IP filtering, click the Add button.

IP Filtering – Incoming
The Inbound Filter allows you to create a filter rule to allow incoming IP
traffic by specifying a filter name and at least one condition on this
window. All of the specified conditions in this filter rule must be satisfied
for the rule to take effect. By default, all incoming IP traffic from the
Internet is blocked when the firewall is enabled.

MAC Filtering
The MAC Filtering button appears when configuring WAN interface in Bridging.
MAC filtering are used to block or allow various types of packets through
the WAN/LAN interface. This may be done for security or to improve
network efficiency. The rules are configured for individual devices based
on MAC address. Filter rules can be set up for source, destination or both.
You can set up filter rules and disable the entire set of rules without
loosing the rules that have been configured.
Click Change Policy to configure the global policy as Forwarded or
Blocked.
If you are setting up the MAC filtering, click the Add button.

Quality of Service
QoS or Quality of Service allows your Router to help prioritize the data packet flow in your Router and network. This is very important for time
sensitive applications such as VoIP where it may help prevent dropped calls. Large amounts of non-critical data can be scaled so as not to affect
these prioritized sensitive real-time programs.
To access the QoS – Queue Management Configuration window, click the Quality of Service button in the Advanced Setup directory.
This window allows you to set up QoS on the Router. When you are
finished, click on the Save/Apply button.

QoS Classification
Choose Add or Remove to configure network traffic classes.
Use this window to create a traffic class rule to classify the upstream
traffic, assign a queue that defines the precedence and the interface, and
optionally overwrite the IP header DSCP byte. A rule consists of a class
name and at least one condition. Please remember that all of the specified
conditions on this window must be met for the rule to take effect.

Routing
To access the Routing windows, click the Routing button in the Advanced Setup directory.
Default Gateway
If the Enable Automatic Assigned Default Gateway checkbox is ticked,
the Router will accept the first default gateway assignment received from
one of the enabled PPPoA, PPPoE, or MER/DHCP enabled PVC(s).
If this checkbox is not ticked, enter the static default gateway and/or a
WAN interface. Click the Save/Apply button when you are finished.

DNS
To access the DNS windows, click the DNS button in the Advanced Setup directory. The NAT button appears when configuring WAN interface in
PPPoA, PPPoE, MER or IPoA.
DNS Server
If you have not been given specific DNS server IP addresses or if the
Router is not pre-configured with DNS server information, tick the Enable
Automatic Assigned DNS checkbox. Auto discovery DNS instructs the
Router to automatically obtain the DNS IP address from the ISP through
DHCP. If your WAN connection uses a Static IP address, auto discovery
for DNS cannot be used.
If you have DNS IP addresses provided by your ISP, deselect the Enable
Automatic Assigned DNS checkbox and enter these IP addresses in the
available entry fields for the Primary DNS Server and the Secondary DNS
Server. Click the Save button when you are finished.
Dynamic DNS
The Router supports Dynamic DNS (Dynamic Domain Name Service).
The Dynamic DNS service allows a dynamic public IP address to be
associated with a static host name in any of the many domains, allowing
access to a specified host from various locations on the Internet. This is
enabled to allow remote access to a host by clicking a hyperlinked URL in
the form hostname.dyndns.org, Many ISPs assign public IP addresses
using DHCP, this can make it difficult to locate a specific host on the LAN
using standard DNS. If for example you are running a public web server or
VPN server on your LAN, this ensures that the host can be located from
the Internet if the public IP address changes. DDNS requires that an
account be setup with one of the supported DDNS providers.
Click Add to see the Add DDNS Settings section.
Section 3 – Configuration
D-Link DSL-2650U User Manual 64
Enter the required DDNS information, click the Save/Apply button to save
the information.
Note
DDNS requires that an account be setup with one of the supported
DDNS servers prior to engaging it on the Router. This function will not
work without an accepted account with a DDNS server.
