2) Setting up wireless encryption
RT-N15 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 RT-N15, contact your network
administrator for advice.
Click Wireless -> Interface to open the conguration page.
Encryption
The encryption modes supported by RT-N15 are: WEP (64bits), WEP (128bits),
TKIP, AES, and TKIP+AES.
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 hexadecimal digits for 64-bit key or 26 hexadecimal digits
for 128-bit 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.
Note: For 802.11n performance, select 40MHz bandwidth. Channel option will
depend on the bandwidth that you select.

2. Select Yes to enable virtual
server. For example, if
host 192.168.1.100 is the
FTP server that the user
will access, 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 RT-N15 include: Open, shared key,
WPA-PSK, WPA, and Radius with 80.211x.
Open: This option disables authentication protection for wireless network. Under
Open mode, any IEEE802.11b/g client can connect to your wireless network.
Shared: This mode uses the WEP keys currently in use for authentication.
WPA/WPA2 and WPA-PSK/WPA2-PSK: 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 methods: 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.
1. Click Virtual Server in NAT Setting folder to open the
NAT conguration page.

and activate the settings.
5) Setting up DDNS
DNS enables host who uses static IP address to associate with a domain name;
for dynamic IP users, 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. Thus, the Internet user can always access
your network.
1. Click DDNS 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 the Internet and make all services provided by this
host available to outside users, enable Virtual 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.
