Address Mapping
Network Address Translation (NAT) allows IP addresses used in a private 
local network to be mapped to one or more addresses used in the public, 
global Internet. This feature limits the number of public IP addresses 
required from the ISP and also maintains the privacy and security of the 
local network. We allow one public IP address to be mapped to a pool of 
local addresses.
Click Save Settings to proceed, or Cancel to change your settings.

Virtual Server
Using this feature, you can put PCs with public IPs and PCs with private 
IPs in the same LAN area.
If you configure the Barricade as a virtual server, remote users accessing 
services such as web or FTP at your local site via public IP addresses can 
be automatically redirected to local servers configured with private IP 
addresses. In other words, depending on the requested service (TCP/UDP 
port number), the Barricade redirects the external service request to the 
appropriate server (located at another internal IP address).
For example, if you set Type/Public Port to TCP/80 (HTTP or web) and 
the Private IP/Port to 192.168.2.2/80, then all HTTP requests from 
outside users will be transferred to 192.168.2.2 on port 80. Therefore, by 
just entering the IP address provided by the ISP, Internet users can access 
the service they need at the local address to which you redirect them. 
The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.

Special Applications
Some applications, such as Internet gaming, videoconferencing, Internet 
telephony and others, require multiple connections. These applications 
cannot work with Network Address Translation (NAT) enabled. If you 
need to run applications that require multiple connections, use the 
following screen to specify the additional public ports to be opened for 
each application.
Click the List of well known special applications link for more 
information.
Specify the public port number normally associated with an application in 
the Trig ger Port field. Set the protocol type to TCP or UDP, then enter 
the ports that the application requires. The ports may be in the format of a 
single port, or in a range, e.g., 72-96, or a combination of both.

Popular applications requiring multiple ports are listed in the Popular 
Applications field. From the drop-down list, choose the application and 
then choose a row number to copy this data into.
Note:Choosing a row that already contains data will overwrite the 
current settings.
For a full list of ports and the services that run on them, see

NAT Mapping Table
This page displays the current NAPT (Network Address Port Translation) 
address mappings.
The NAT address mappings are listed 20 lines per page, click the control 
buttons to move forwards and backwards. As the NAT mapping is 
dynamic, a Refresh button is provided to refresh the NAT Mapping Table 
with the most updated values.
The content of the NAT Mapping Table is described as follows:
• Protocol - protocol of the flow.
• Local IP - local (LAN) host’s IP address for the flow.
• Local Port - local (LAN) host’s port number for the flow.
• Pseudo IP - translated IP address for the flow.
• Pseudo Port - translated port number for the flow.
• Peer IP - remote (WAN) host’s IP address for the flow.
• Peer Port - remote (WAN) host’s port number for the flow.

System
This section includes all the basic configuration tools for the Barricade, 
such as time settings, password settings, and remote management.
Time Settings
Set the time zone and time server for the Barricade. This information is 
used for log entries and client access control.
Check Enable Automatic Time Server Maintenance to automatically 
maintain the Barricade’s system time by synchronizing with a public time 
server over the Internet. Then configure two different time servers by 
selecting the options in the Primary Server and Secondary Server fields.

Password Settings
Use this page to restrict access based on a password. For security you 
should assign one before exposing the Barricade to the Internet.
Passwords can contain from 3 to12 alphanumeric characters and are case 
sensitive.
Note:If your password is lost, or you cannot gain access to the user 
interface, press the Reset button (colored blue) on the rear panel 
(holding it down for at least six seconds) to restore the factory 
defaults. The default password is “smcadmin”.
Enter a maximum Idle Time Out (in minutes) to define a maximum period 
of time an inactive login session will be maintained. If the connection is 
inactive for longer than the maximum idle time, it will be logged out, and 
you will have to log in to the web management system again. Setting the 
idle time to 0, will mean the connection never times out.
(Default: 10 minutes)
