Routing
This page displays the routing details configured for the router.
A gateway value of 0.0.0.0 means there is no next hop. The IP address is directly connected to the
router on the interface specified, LAN or WAN. A value of 0.0.0.0 in both the destination IP and
netmask means that this is the default route.
Logs
The router automatically logs (records) events of possible interest in it’s internal memory. If there isn’t
enough internal memory for all events, logs of older events are deleted but logs of the latest events
are retained. The Logs option allows you to view the router logs. You can define what types of events
you want to view and the level of the events to view. This router also has external Syslog Server
support so you can send the log files to a computer on your network that is running a Syslog utility.
Log Options
You can select the types of messages that you want to display from the log.
Firewall & Security, System, and Router Status messages can be selected.
There are three levels of message importance: Informational, Warning, and
Critical. Select the levels that you want displayed in the log.
Will filter the log results so that only the selected options appear.

Securing Your Network
1.
Change Admin Password
Changing the password to access your new router is the first step in securing your network.
This can
done through the Wizard or on the Admin Page of the Tools tab.
There is no password by default and
hackers will know this when trying to access your network.
Make sure that the password you choose
is not commonly known or something that is easy to guess such as your last name or your pet’s
name. Try using a combination of letters and numbers to deter intruders from hacking into your
network. Your private information should be kept private.
2.
Disable DHCP and use Static IP addresses or Use Static DHCP and limit scope to the
amount of users on your network.
In the event that an intruder manages to gain access to your network, having DHCP enabled makes
it easier for the intruder to access other computers on your network. There are two methods for
getting around this. One is to disable DHCP and use static IP addressing on all the devices connected
to your network. This would mean that the intruder would have to know what IP network your devices
are on in order to access them. The second way is to change the scope of the DHCP server to only
include enough IP addresses for the devices in your network. You can then use the Static DHCP
feature of the router to assign an IP address to each device on your network. Static DHCP still
dynamically assigns an IP address to your network devices but only allows for those defined devices
to obtain an IP address.
3.
Change the default LAN IP address
Change the default LAN IP address from 192.168.0.1 to an alternate IP address. There are 3 ranges
of IP addresses that have been reserved for use on Private Networks.
10.0.0.0
-
10.255.255.255 (10.0.0.0/8)
172.16.0.0
-
172.31.255.255 (172.16.0.0/12)
192.168.0.0
-
192.168.255.255 (192.168.0.0/16)
D-Link routers use 192.168.0.1 as their default LAN IP address. Choosing an alternate IP address
lessens the probabilty of an intruders knowing what IP network your devices are on.

Set up MAC Filtering
Each networking device (router, network card, etc) on a network contains a unique hexadecimal
number that identifies that specific product.
This number is referred to as a MAC address.
MAC
filtering allows you to create a list of the MAC address of each device on your network and only
allows these specific devices to associate with your network. With this feature enabled, devices
attempting to connect to your network with a MAC address that is not in the list you created, will be
denied access.
