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 identification. 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.

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.
