DDNS SETUP

DDNS (Dynamic Domain Name Service) allows an ―internet domain name‖ to be assigned to a computer/router which has

a dynamic IP address. This makes it possible for other internet devices to connect to the computer/router without needing

to trace the changing IP addresses themselves. To enable DDNS, you will first need to sign up for DDNS services from

DynDNS.org, TZO.com or ZoneEdit.com.

DDNS is useful when combined with the virtual server feature. It allows other internet users to connect to your virtual

server by using a domain name, rather than an IP address. The DDNS service helps users to locate the right IP address by

the domain name.

For example, you wish to set up a personal web server. However, you obtain a different IP address from your ISP every

time you connect to the internet. The dynamic IP address you have will cause difficulty for other internet users to find your

web server. In this case, you will need to enable DDNS, so other users can connect to you through a fixed domain name to

disregard the potential varying IP addresses behind the server.

1.

Register with one of the DDNS providers (DynDNS.org, TZO.com or ZoneEdit.com) before you configure DDNS

on the ZyXEL VFG6005 Series VPN Firewall Gateway.

2.

CHAPTER6 WIRELESS SETTINGS

6.1

BASIC SETUP

Multiple SSIDs allow the ability for separate security mode and key settings to be set by users for both convenience and

increased protection. Users are able to configure their network devices to access the first SSID with the WPA2 PSK

(Pre-Shared Key) and secret key, whilst share the second SSID with WEP and the periodically changed key for visitors. In

addition, users are able to isolate these SSIDs to avoid malicious attacks and prevent certain access for visitors using the

second SSID. This then provides users an extremely convenient approach to share the wireless access, provide access

internet access for visitors, while possessing a strong security protection system at all times.

6.1.2

SSID Settings

Users are able to configure each SSID with its own attributes. Further, various security modes are available based on the

user‘s needs and preference: Disable, WEP, WPA Pre

-Shared Key, WPA, WPA2 Pre-Shared Key, and WPA2. However, it

is important to note that all devices under the wireless network must use the same security mode.

You can configure the security settings of your wireless network to suit your desired preference. Different methods will

grant different levels of security. Using encryption - data packet is encrypted before transmission - can prevent data

packets from being intruded on by un-trusted parties. However, please note that the higher the security level is, the lower

the data throughput becomes.
