L2TP
Enter the L2TP Account ID and Password assigned by your ISP in the 
appropriate fields. If your ISP uses DHCP service, enable the Get IP by 
DHCP. Then enter the L2TP Server Address provided by your ISP. 
Click on the Disconnect after x minutes of no activity and then 
enter the idle time for the Internet connection. This is the period of time 
for which the connection to the Internet is maintained during inactivity. If 
your ISP charges you by the minute, you should change the idle time out to 
one minute. 
Most ISPs provide a DNS server for speed and convenience. Since your 
Service Provider may connect to the Internet with dynamic IP settings, it is 
likely that the DNS server IP’s are also provided dynamically. Clicking on 
the Click here to enter your DNS Settings for DNS configuration. 
See “DNS” on page 4-22.
Click SAVE SETTINGS to proceed, or Clear to change your settings

Static IP
If your Service Provider has assigned a fixed IP address, enter the assigned 
IP address, subnet mask and the gateway address on this screen.

Clone MAC Address
Some ISPs require you to register your MAC address with them. If this is 
the case, and you have previously registered the MAC address of another 
device, the MAC address of the Barricade must be changed to the MAC 
address that you have registered with your ISP.

DNS
A Domain Name Server (DNS) is an index of IP addresses and web 
addresses. If you type a web address into your browser, such as 
www.smc.com, a DNS server will find that name in its index and find the 
matching IP address: xxx.xxx.xxx.xxx. Most ISPs provide a DNS server 
for speed and convenience. Since your Service Provider may connect to 
the Internet with dynamic IP settings, it is likely that the DNS server IP’s 
are also provided dynamically. However, if there is a DNS server that you 
would rather use, you need to specify the IP address here.

LAN Settings
You can enable DHCP to dynamically allocate IP addresses to your client 
PCs, or configure filtering functions based on specific clients or protocols. 
The Barricade must have an IP address for the local network.
The LAN Settings parameters are listed below.
Parameter Description
LAN IP
IP Address The IP address of the Barricade.
IP Subnet Mask The IP subnet mask.
DHCP Server DHCP allows individual computers to obtain the TCP/IP 
configuration at startup from a centralized DHCP server. To 
dynamically assign an IP address to a client PC, enable the 
DHCP (Dynamic Host Configuration Protocol) function.

Lease Time The length of time the DHCP server will reserve the IP 
address for each computer. Setting lease times for shorter 
intervals such as one day or one hour frees IP addresses after 
the specified period of time. This also means that a particular 
computer’s IP address may change over time. If you have set 
any advanced features such as DMZ, this is dependent on the 
IP address. For this reason, you will not want the IP address 
to change.
IP Address Pool The DHCP IP Address Pool is the range of IP addresses set 
aside for dynamic assignment to the computers on your 
network.
Start IP This field indicates the first of the contiguous IP addresses in 
the IP address pool.
End IP This field indicates the last of the contiguous IP addresses in 
the IP address pool.
Domain Name The domain name is the name you assign to your network. Parameter Description 
						

							WIRELESS

Wireless
The Barricade also operates as a wireless access point, allowing wireless 
computers to communicate with each other. To configure this function, all 
you need to do is to enable the wireless function, define the radio channel, 
the SSID, and the security options. 
Check Enable and click SAVE SETTINGS.

Channel and SSID
You must specify a common radio channel and SSID (Service Set ID) to 
be used by the Barricade and all of its wireless clients. Be sure you 
configure all of its clients to the same values.
 
Parameter Description
Wireless Channel The radio channel used by the wireless router and its clients to 
communicate with each other. This channel must be the same 
on the Barricade and all of its wireless clients.
The Barricade will automatically assign itself a radio channel, or 
you may select one manually.
Extension 
ChannelSetting the Bandwith Mode as 20/40MHz allows you to use this 
extension channel as the secondary channel for doubling the 
bandwith of your wireless network.
SSID Service Set ID. The SSID must be the same on the Barricade 
and all of its wireless clients. (Default: SMC)
Wireless  Mode This device supports 11n, 11g and 11b wireless networks. Make 
your selection depending on the type of wireless network that 
you have. SMC recommend using “Mixed 802.11n, 802.11g and 
802.11b” to provide compatibility with 11n, 11g and 11b 
wireless clients. 
						

							WIRELESS

Bandwidth  • 20MHz: Sets the operation bandwidth as 20 MHz.
• 20/40MHz: Allows automatic detection of the operation 
bandwidth between 20 MHz and 40 MHz. 
Choosing the bandwidth mode as 20/40MHz allows you to 
use the extension channel.
Broadcast  SSID  Enable or disable the broadcasting of the SSID. Disabling SSID 
broadcast will provide increased security by hiding the SSID of 
your wireless network.
Protected Mode Enabling this function to ensure the best performance of your 
11n throughput in case there is a lot of interference from the 
11g and 11b devices in the wireless network.
802.11e/WMM 
QoSEnable or disable the use of QoS. The QoS (Quality of Service) 
function allows you to differentiate WMM (Wi-Fi Multimedia) 
traffic and provide it with high-priority forwarding service Parameter Description

Access Control
Using the Access Control functionality, you can restrict access based on 
MAC address. Each PC has a unique identifier known as a Medium Access 
Control (MAC) address. With MAC filtering enabled, the computers 
whose MAC address you have listed in the filtering table will be able to 
connect (or will be denied access) to the Barricade.
