1) Setting up Wireless Encryption
WL-520GU/GC provides a set of encryption and authentication methods to meet
the different demands of home, SOHO, and enterprise users. Before setting
up encryption and authentication for WL-520GU/GC, contact your network
administrator for advice.
Click Wireless -> Interface to open the conguration page.
1) Choosing an Appropriate Operation Mode

WL-520GU/GC Broad Range Wireless Family Router User Manual

Encryption
The encrytion modes supported by WL-520GU/GC are: WEP-64bits, WEP-128bits,
WPA-Personal, WPA2-Personal, WPA-Auto-Personal(TKIP. AES. TKIP+AES),
WPA-enterprise, WPA2-enterprise, WPA-Auto-Enterprise (TKIP. AES. TKIP+AES),
Radius with 802.1x
WEP stands for Wired Equivalent Privacy, it uses 64bits or 128bits static keys
to encrypt the data for wireless transmission. To setup WEP keys, set WEP
Encryption to WEP-64bits or WEP-128bits, then manually type in four sets WEP
Keys (10 hexadicimal digits for 64-bits key or 26 hexadicimal digits for 128-bits
key). You can also let the system generate the keys by entering a Passphrase.
TKIP stands for Temporal Key Integrity Protocol. TKIP dynamically generates
unique keys to encrypt every data packet in a wireless session.
AES stands for Advanced Encryption Standard. This solution offers stronger
protection and increases the complexity of wireless encryption.
TKIP+AES is used when both WPA and WPA2 clients co-exist in the wireless
network.
WPA-Personal protects unauthorized network access by utilizing a set-up
password.
WPA-enterprise veries network users through a server.

2. Select Yes to enable virtual
server. For example, if host
192.168.1.100 is FTP server
which is to be accessed by
Internet user, it means all
packets from Internet with
destination port as 21 are to
be directed to the host. Set
Well-known Application to
FTP. Port range to 21, Local
IP to the host IP, Local Port
to 21, Protocol to TCP.
3. Click Finish.
4. Click Save & Restart to
restart the wireless router
and activate the settings.
Authentication
The authentication methods supported by WL-520GU/GC include: Open, Shared
key, WPA-Personal, WPA2-Personal, WPA-Auto-Personal (TKIP. AES. TKIP+AES),
WPA-Enterprise, WPA2-Enterprise, WPA-Auto-Enterprise (TKIP. AES. TKIP+AES),
and Radius with 802.1x.
Open: This option disables authentication protection for wireless network.
Shared Key: This mode uses the WEP keys currently in use for authentication.
WPA-Enterprise, WPA2-Enterprise, WPA-Personal, WPA2-Personal, WPA-
Auto-Personal: WPA stands for WiFi-Protected Access. WPA provides two
security modes: WPA for enterprise network, and WPA-PSK for home and SOHO
users. For enterprise network, WPA uses the already existing RADIUS server for
authentication; for home and SOHO user, it provides Pre-Shared Key (PSK) for
user identication. The Pre-Shared Key consists of 8 to 64 characters.
Radius with 802.1x: Similar with WPA, this solution also uses RADIUS server
for authentication. The difference lays on the encryption mothods: WPA adopts
TKIP or AES encryption methods, while Radius with 802.1X does not provide
encryption.
When authentication and encryption are set, click Finish to save the settings and
restart the wireless router.
3) Setting up Virtual Server in Your LAN
Virtual Server is a Network Address Translation (NAT)
function which turns a computer within a LAN into a server
by allowing data packets of certain service, such as HTTP,
from Internet.

5) Setting up DDNS
DNS enables host who uses static IP address to associate with a domain name;
for dynamic IP user, they can also associate with a domain name via dynamic
DNS (DDNS). DDNS requires registering and account-creating at DDNS service
providers' website. The DDNS server updates your IP address information once
you are assigned to a new IP address. Therefore, Internet user can always access
your network.
1. Click Miscellaneous from IP Cong folder.
2. Select Yes to enable the
DDNS service. If you do
not have a DDNS account,
click Free Trial to register
for a trial account.
4) Setting up Virtual DMZ in Your LAN
To expose an internal host to Internet and make all services provided by this host
available to outside users, enable Vitural DMZ function to open all ports of the host.
This function is useful when the host plays multiple roles such as HTTP server and
FTP server. However, in doing this, your network becomes less secure.
Note: When the virtual DMA is enabled, the wireless/wired
clients of the WL-520GU/GC will not be protected.
