Setup Advanced Tools Status Support


The Admin option is used to set a password for access to the Web-based management. By default there is no password configured. It is highly recommended that you create a password to keep your new router secure.

Admin Password
Enter a password for the user "admin", who will have full access to the Web-based management interface.
User Password
Enter a password for the user "user", who will have read-only access to the Web-based management interface.
Gateway Name
The name of the router can be changed here.
Enable Remote Management
Enabling Remote Management allows you to manage the router from anywhere on the Internet. Disabling Remote Management allows you to manage the router only from computers on your LAN.
Remote Admin Port
The port that you will use to address the management interface from the Internet. For example, if you specify port 1080 here, then, to access the router from the Internet, you would use a URL of the form:
Remote Admin Inbound Filter
Select a filter that controls access as needed for this admin port. If you do not see the filter you need in the list of filters, go to the Advanced → Inbound Filter screen and create a new filter.


The Time Configuration option allows you to configure, update, and maintain the correct time on the router's internal system clock. From this section you can set the time zone that you are in and set the Time Server. Daylight saving can also be configured to automatically adjust the time when needed.

Time Configuration
Current Router Time
Displays the time currently maintained by the router. If this is not correct, use the following options to configure the time correctly.
Time Zone
Select your local time zone from pull down menu.
Enable Daylight Saving
Check this option if your location observes daylight saving time.
Daylight Saving Offset
Select the time offset, if your location observes daylight saving time.
DST Start and DST End
Select the starting and ending times for the change to and from daylight saving time. For example, suppose for DST Start you select Month="Oct", Week="3rd", Day="Sun" and Time="2am". This is the same as saying: "Daylight saving starts on the third Sunday of October at 2:00 AM."
Automatic Time Configuration
Enable NTP Server
Select this option if you want to synchronize the router's clock to a Network Time Server over the Internet. If you are using schedules or logs, this is the best way to ensure that the schedules and logs are kept accurate.

Note that, even when NTP Server is enabled, you must still choose a time zone and set the daylight saving parameters.

NTP Server Used
Select a Network Time Server for synchronization. You can type in the address of a time server or select one from the list. If you have trouble using one server, select another.
Set the Date and Time Manually
If you do not have the NTP Server option in effect, you can either manually set the time for your router here, or you can click the Copy Your Computer's Time Settings button to copy the time from the computer you are using. (Make sure that computer's time is set correctly.)

Note: If the router loses power for any reason, it cannot keep its clock running, and will not have the correct time when it is started again. To maintain correct time for schedules and logs, either you must enter the correct time after you restart the router, or you must enable the NTP Server option.


This section allows you to archive your log files to a Syslog Server.

Enable Logging to Syslog Server
Enable this option if you have a syslog server currently running on the LAN and wish to send log messages to it.
Syslog Server IP Address
Enter the LAN IP address of the Syslog Server.

Email Settings

The Email feature can be used to send the system log files, router alert messages, and firmware update notification to your email address.

Enable Email Notification
When this option is enabled, router activity logs or firmware upgrade notifications can be emailed to a designated email address, and the following parameters are displayed.
Email Settings
From Email Address
This email address will appear as the sender when you receive a log file or firmware upgrade notification via email.
To Email Address
Enter the email address where you want the email sent.
SMTP Server Address
Enter the SMTP server address for sending email.
Enable Authentication
If your SMTP server requires authentication, select this option.
Account Name
Enter your account for sending email.
Enter the password associated with the account.
Verify Password
Re-type the password associated with the account.
Email Log When Full or on Schedule
On Log Full
Select this option if you want logs to be sent by email when the log is full.
On Schedule
Select this option if you want logs to be sent by email according to a schedule.
If you selected the On Schedule option, select one of the defined schedule rules. If you do not see the schedule you need in the list of schedules, go to the Tools → Schedules screen and create a new schedule.

Note: Normally email is sent at the start time defined for a schedule, and the schedule end time is not used. However, rebooting the router during the schedule period will cause additional emails to be sent.


This section allows you to manage the router's configuration settings, reboot the router, and restore the router to the factory default settings. Restoring the unit to the factory default settings will erase all settings, including any rules that you've created.

Save Settings To Local Hard Drive
This option allows you to save the router's configuration to a file on your computer. Be sure to save the configuration before performing a firmware upgrade.
Load Settings From Local Hard Drive
Use this option to restore previously saved router configuration settings.
Restore To Factory Default Settings
This option restores all configuration settings back to the settings that were in effect at the time the router was shipped from the factory. Any settings that have not been saved will be lost. If you want to save your router configuration settings, use the Save Settings option above.
Reboot The Device
This restarts the router. Useful for restarting when you are not near the device.


The Firmware Upgrade section can be used to update to the latest firmware code to improve functionality and performance. If you would like to be notified when new firmware is released, place a checkmark in the box next to Email Notification of Newer Firmware Version.

To upgrade the firmware, follow these steps:

  1. Click the Browse button to locate the D-Link upgrade file on your computer.
  2. Once you have found the file to be used, click the Upload button below to start the firmware upgrade process. This can take a minute or more.
  3. Wait for the router to reboot. This can take another minute or more.
  4. Confirm updated firmware revision on status page.
Firmware Information

Here are displayed the version numbers of the firmware currently installed in your router and the most recent upgrade that is available.

Firmware Upgrade

Note: Firmware upgrade cannot be performed from a wireless device. To perform an upgrade, ensure that you are using a PC that is connected to the router by wire.

Note: Some firmware upgrades reset the configuration options to the factory defaults. Before performing an upgrade, be sure to save the current configuration from the Tools → System screen.

Once you have a firmware update on your computer, use this option to browse for the file and then upload the information into the router.
Firmware Upgrade Notification Options
Automatically Check Online for Latest Firmware Version
When this option is enabled, your router will check online periodically to see if a newer version of the firmware is available.
Email Notification of Newer Firmware Version
When this option is enabled, an email will be sent to the email address configured in the email section whenever new firmware is available. You must have Email Notification enabled from the Tools → Email Settings page.

Dynamic DNS

The Dynamic DNS feature allows you to host a server (Web, FTP, Game Server, etc.) using a domain name that you have purchased ( with your dynamically assigned IP address. Most broadband Internet Service Providers assign dynamic (changing) IP addresses. When you use a Dynamic DNS service provider, your friends can enter your host name to connect to your server, no matter what your IP address is.

Enable Dynamic DNS
Enable this option only if you have purchased your own domain name and registered with a dynamic DNS service provider. The following parameters are displayed when the option is enabled.
Server Address
Select a dynamic DNS service provider from the pull-down list, or you may enter a dynamic DNS service provider manually.
Host Name
Enter your host name, fully qualified; for example:
Username or Key
Enter the username or key provided by your service provider. If the Dynamic DNS provider supplies only a key, enter that key in all three fields.
Password or Key
Enter the password or key provided by your service provider. If the Dynamic DNS provider supplies only a key, enter that key in all three fields.
Verify Password or Key
Re-type the password or key provided by your service provider. If the Dynamic DNS provider supplies only a key, enter that key in all three fields.
The time between periodic updates to the Dynamic DNS, if your dynamic IP address has not changed. The timeout period is entered in hours.

Note: If a dynamic DNS update fails for any reason (for example, when incorrect parameters are entered), the router automatically disables the Dynamic DNS feature and records the failure in the log.

Note: After configuring the router for dynamic DNS, you can open a browser and navigate to the URL for your domain (for example and the router will attempt to forward the request to port 80 on your LAN. If, however, you do this from a LAN-side computer and there is no virtual server defined for port 80, the router will return the router's configuration home page. Refer to the Advanced → Virtual Server configuration page to set up a virtual server.
