Router Password:
Changing the password for the AP Router is as easy as typing the password into
the
Enter
New Password
field. Then, type it again into the Re-enter to confirm.
* Click the
Apply
button to save the setting.
Use the default password when you first open the configuration pages, after you have configured
these settings, you should set a new password for the Router (using the Security screen). This will
increase security, protecting the Router from unauthorized changes.
VPN Pass-Through:
Virtual Private Networking (VPN) is typically used for work-related networking.
For VPN tunnels, the Router supports IPSec Pass-Through, L2TP Pass-Through, and PPTP Pass-
Through.
IPSec
- Internet Protocol Security (IPSec) is a
suite of protocols used to implement secure
exchange of packets at the IP layer. To allow IPSec tunnels to pass through the Router, IPSec
Pass-Through is enabled by default. To disable IPSec Pass-Through, uncheck the box next to
IPSec
.
L2TP
- Layer 2 Tunneling Protocol is a protocol used to tunnel Point-to-Point Protocol (PPP)
over the Internet. To allow L2TP tunnels to pass through the Router, L2TP Pass-Through is
enabled by default. To disable L2TP Pass-Through, uncheck the box next to
L2TP
.
PPTP
- Point-to-Point Tunneling Protocol is the method used to enable VPN sessions to a
Windows NT 4.0 or 2000 server. To allow PPTP tunnels to pass through the Router, PPTP
Pass-Through is enabled by default. To disable PPTP Pass-Through, uncheck the box next to
PPTP
.
Web Filters:
Using the Web Filters feature, you may enable up to four different filters.

DMZ:
The DMZ hosting feature allows one local user to be exposed to the Internet for use of a
special-purpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all the
ports at the same time to one PC. The Port Forwarding feature is more secure because it only opens
the ports you want to have opened, while DMZ hosting opens all the ports of one computer, exposing
the computer so the Internet can see it.
Any PC whose port is being forwarded must have its DHCP client function disabled and should have a
new static IP address assigned to it because its IP address may change when using the DHCP
function.
1.
To expose one PC, select
Enable
.
2.
Enter the computer's IP address in the
DMZ Host IP Address
field.
3.
Click the
Apply
button.
Block WAN Request:
By enabling the Block WAN Request feature, you can prevent your network
from being "pinged," or detected, by other Internet users. The Block WAN Request feature also
reinforces your network security by hiding your network ports. Both functions of the Block WAN
Request feature make it more difficult for outside users to work their way into your network. This
feature is enabled by default. Select
Disable
to disable this feature.
* Check all the settings and click

access the Router's web-based utility.
Note: If the Remote Management feature is enabled, anyone who knows the Router's Internet IP
address and password will be able to alter the Router's settings.
