SPECIAL FEATURES
1. What DDNS providers does the E900 support?
DynDNS.org and TZO.com
2. How many connection types does the E900 support?
The router supports six (6) connection types: Automatic Configuration – DHCP, Static
IP, PPPoE, PPTP, Telstra Cable, and L2TP.
3. Does E900 support AP Isolation?
No.
4. Does E900 support wireless and Internet Access Priority QOS?
Yes.

5. Does E900 support transmission of the log information to a log server?
No.
6. Does E900 lose the settings you have customized when its firmware has been
updated?
Yes. Before upgrading the firmware of your E900, write down all your customized
settings. After upgrading its firmware, you will have to re-enter all of your
configuration settings.
7. What is Radio Band, Standard and Wide?
The Radio Band gives you two (2) options: Auto and Standard - 20MHz channel,
Standard channel is what all B/G/N devices use. If you select Wide channel for the
Radio Band setting, then Wireless-N can use two channels: a primary one (Auto) and
a secondary one (Standard Channel). This will improve Wireless-N performance.
8. What is "MAC address clone" and what is it for?
Some Internet Service Providers, especially Cable companies, require you to register
the MAC Address of the modem, router or Ethernet adapter of the computer in order
to access the Internet. If you do not wish to re-register the MAC address currently
registered with your ISP, you may assign the MAC address you have currently
registered with your ISP to the router using the MAC Address Clone feature.
If you want to clone the MAC address of the computer that you are using to configure
the router, and then click the Clone My MAC Address button. The router will
automatically detect your computer’s MAC address, so you do NOT have to call your
ISP to change the registered MAC address to the router’s MAC address. It is
recommended that the computer registered with the ISP is used to enable this feature
on the router.
9. What is Diagnostics and what is it for?
Diagnostics is used to check internet connect and application "ping”, "traceroute”
command to check your network’s connectivity to the Internet.
10. What is Port Forwarding?

Port Forwarding allows you to set up public services on your network, such as web
servers, ftp servers, e-mail servers, or other specialized Internet applications.
11. What is Port Triggering?
Port Triggering will forward port based on the incoming port specified. Check your
software application to find out what is necessary to enter in these fields.
NOTE: You can set up to ten (10) port triggering entries.
12. What is "DMZ" and what is it for?
Demilitarized Zone (DMZ) allows one local user to be exposed to the Internet for use
of a special-purpose service such as Internet gaming and videoconferencing. DMZ
hosting forwards all the ports at the same time to one computer. However, Port
Range Forwarding is more secure because it only opens the ports you want to
forward, while DMZ hosting opens all the ports of one computer, exposing the
computer to the Internet.
13. How many Network modes supported in E900?
It supports three (3) Network Modes - 802.11b, 802.11g, 802.11n.
14. What is wireless MAC Filter and what is it for?
Wireless MAC Filter prevents or allows connectivity to the wireless network with the
use of the MAC address of the wireless device.
