4.9

LAN MAC Filtering

Your router can be configured to restrict access to the Internet, email or other network services.

Restrictions can be set for a single computer, a range of computers or multiple computers.

4.9.1

MAC Filtering

The MAC address filter is a powerful security feature that allows you to specify which computers are

allowed on your network. Any computer attempting to access your network must be specified in the filter

list or it will be denied access. When you enable this feature, you must enter the MAC address of each

client (computer) on your network in order to allow network access to each.

MAC Services Blocking can be set in three modes.

•

Disable. In this mode, there are no restrictions on any devices connected to the router, whether

through Wi-Fi or Ethernet ports

•

Deny. In this mode, the service table shows the client MAC address being blocked by the router.

•

Allow. In this mode, the service table shows the client MAC address allowed by the router.

To modify the service table (add, change address or remove clients), enter the correct value and click

“Apply”.

Note: You will not be able to delete the MAC address of the computer you are using to access the router’s

administrative functions.

4.10 WAN Setup

Clicking on the “WAN Setup” sub-heading in the “Advanced” list will take you to the “WAN Setup” page.

This is where you can enable or disable the router’s DMZ, Internet Ping, and HTTP-related items.

4.10.1

Demilitarized Zone (DMZ

)

The DMZ feature allows you to specify one computer on your internal network to be placed outside the

firewall. This may be necessary if the firewall is causing problems with a game, video conferencing, or

other application. Use this feature on a temporary basis. The computer in the DMZ is NOT protected from

hacker attacks.

4.10.2

WAN Ping Blocking

Computer hackers use what is known as “pinging” to find potential victims on the Internet. By pinging a

specific IP address and receiving a response, a hacker can determine that something of interest might be

at that IP address. You can set your router so it will not respond to a hacker’s ICMP ping, increasing the

level of security provided by your router.

If it is necessary to turn on the ping response, select “Allow Ping Response on WAN port” and click

“Apply”..

4.10.3

Disable NAT

This feature disables all NAT router functionality.

4.10.4

Enable Access to Router

Managemnet via Internet

This feature allows users with access to the Wi-Fi network to login to the router interface. Be aware that

the default settings “username and password” = “admin” a good security measure against intruders to your

network. If you wish to restrict the access to the router interface to be accessible only via ethernet cable,

please uncheck this box.

4.11 LAN IP Setup

Clicking on the header of the “LAN IP Setup” tab will take you to its header page.

4.11.1

LAN TCP/IP Setup

The IP address in this instance is referring to the IP address that you use to log into your router (default

192.168.0.1).

If you change this, then in future you will need to log in using the new IP address that you

chosen.

There is no need to change the subnet mask. This is a unique, advanced feature of your router. It is

possible to change the subnet mask, if necessary. Do NOT make changes to the subnet mask unless you

have a specific reason to do so. The default setting is “255.255.255.0”.

4.11.2

Use the Router as a DHCP Server

The DHCP server function makes setting up a network very easy by assigning IP addresses to each

computer on the network automatically. The DHCP server can be turned OFF, if necessary. To do so,

you must manually set a static IP address for each computer on your network. To turn off the DHCP

server, de-select “Use router As DHCP Server” and click “Apply

”.

If at anytime you would like to see which devices are connected to your R90, please press the DHCP

clients table button
