Setup Tab - MAC Clone
Some ISPs require that you register a MAC address, which is a 12-digit code assigned to a unique piece of
hardware for identification. The MAC Clone feature “clones” your network adapter's MAC address onto the
Router, so you don’t have to call your ISP to change the registered MAC address to the Router's MAC address.
The MAC Clone table displays the number of WAN ports you have configured on the
Network
or
Port Management
screen. Their MAC addresses are shown in the MAC Address column. Click the
Edit
in the Config. column to edit
the MAC Clone setting of the selected WAN port. A new screen will appear.
In the
Interface
field, the WAN port number is displayed. To manually clone a MAC address, select
User Defined
WAN MAC Address
, and then enter the 12 digits of your adapter’s MAC address. If you want to clone the MAC
address of the PC you are currently using to configure the Router, then select
MAC Address from this PC
.

Setup Tab - DDNS
10/100 16-Port VPN Router
Setup Tab - DDNS
DDNS (Dynamic Domain Name System) service allows you to assign a fixed domain name to a dynamic WAN IP
address, so you can host your own web, FTP or other type of TCP/IP server in your LAN. The DDNS feature is
disabled by default.
Before configuring DDNS, you need to visit www.dyndns.org and register a domain name. (The DDNS service is
provided by DynDNS.org).
The DDNS table displays the number of WAN ports you have configured on the
Network
or
Port Management
screen. The status of each port’s DDNS setting is shown in the DDNS Service column. Click the
Edit
in the Config.
column to edit the DDNS setting of the selected WAN port. A new screen will appear.
In the
Interface
field, the WAN port number is displayed. Select
DynDNS.org
from the
DDNS Service
drop-down
menu. Enter your DynDNS.org account information in the
User name
and
Password
fields. Enter your host name
in the three
Host Name
fields. For example, if your host name were
myhouse.dyndns.org
, then
myhouse
would go
into the first field,
dyndns
would go into the second field, and
org
would go into the last field.
Then click the
Save Settings
button, and the status of the DDNS function will be updated.
In the Internet IP Address section, the Router’s current Internet IP address is displayed. Because it is dynamic,
this will change.
In the Status section, the status of the DDNS function is displayed. If the status information indicates an error,
make sure you have correctly entered the information for your account with DynDNS.org.
Click the
Save Settings
button to save your changes, or click the
Cancel Changes
button to undo your changes.
Click the
Back
button to return to the
DDNS
screen.

Setup Tab - Advanced Routing
Dynamic Routing
The Router's dynamic routing feature can be used, so the Router will automatically adjust to physical changes in
the network's layout. Using the dynamic RIP protocol, the Router calculates the most efficient route for the
network’s data packets to travel between the source and the destination, based upon the shortest paths. The RIP
protocol regularly broadcasts routing information to other routers on the network. It determines the route that the
network packets take based on the fewest number of hops between the source and the destination.
Working Mode. Select
Gateway
mode if the Router is hosting your network’s connection to the Internet. Select
Router
mode if the Router exists on a network with other routers, including a separate network gateway that
handles the Internet connection. In Router Mode, any computer connected to the Router will not be able to
connect to the Internet unless you have another router function as the gateway.
RIP (Routing Information Protocol). To use dynamic routing for communication of network data, click the
Enabled
radio button. Otherwise, keep the default,
Disabled
.
Receive RIP versions. To use dynamic routing for reception of network data, select the protocol you want:
None
,
RIPv1
,
RIPv2
, or
Both RIP v1 and v2
.
Transmit RIP versions. To use dynamic routing for transmission of network data, select the protocol you want:
None
,
RIPv1
,
RIPv2 - Broadcast
, or
RIPv2 - Multicast
.
Static Routing
If the Router is connected to more than one network or there are multiple routers installed on your network, it
may be necessary to set up static routes. The static routing function determines the path that data follows over
your network before and after it passes through the Router. You can use static routing to allow different IP domain
users to access the Internet through the Router.
Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use
dynamic routing because it enables the Router to automatically adjust to physical changes in the network's
layout.
If you want to use static routing, the Router's DHCP settings must be disabled. Then add routing entries to the
Static Routing table. These entries tell the Router where to send all incoming packets. All of your network routers
should direct the default route entry to the 10/100 16-Port VPN Router.

To create a static route entry, enter the following information:
1.
In the
Destination IP
field, enter the network address of the remote LAN segment. For a standard Class C IP
domain, the network address is the first three fields of the Destination LAN IP, while the last field should be
zero.
2.
In the
Subnet Mask
field, enter the Subnet Mask used on the destination LAN IP domain. For Class C IP
domains, the Subnet Mask is 255.255.255.0.
3.
In the
Default Gateway
field, enter the IP address of your network’s gateway. If this Router is used to connect
your network to the Internet, then the gateway IP is the Router's Internet IP address. If you have another
router handling your network's Internet connection, enter the IP address of that router instead.
4.
In the
Hop Count
field, enter the appropriate value (maximum is 15). This indicates the number of nodes that
a data packet passes through before reaching its destination. A node is any device on the network, such as a
switch, PC, or router.
5.
From the
Interface
drop-down menu, select the appropriate interface. The Interface tells you whether your
network is on the LAN or the WAN (the Internet). If you’re connecting to a sub-network, select
LAN
. If you’re
connecting to another network through the Internet, select the appropriate WAN port option.
6.
Click the
Add to list
button, and configure as many static routing entries as you would like, up to a maximum
of 30. To delete an entry, select it and click the
Delete selected IP
button.
Click the
Save Settings
button to save your changes or click the
Cancel Changes
button to undo your changes.
Click the
Show Routing Table
button to view the current routes and their settings.

DHCP Tab - Setup
Setup
The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server
automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP
server option, all of the PCs on your LAN must be set to obtain an IP address automatically from a DHCP server.
(By default, Windows computers are set to obtain an IP automatically.)
If the Router's DHCP server function is disabled, you have to carefully configure the IP address, subnet mask, and
DNS settings of every computer on your network. Be careful not to assign the same IP address to different
computers.
You can also set up to 30 static IP entries on this screen.
Enable DHCP Server. Check the box to enable the DHCP Server. If you already have a DHCP server on your
network, leave the box unchecked.
Dynamic IP
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. The range is 5-43,200 minutes.
Range Start/End. Enter a starting IP address and ending IP address to create a range of available IP addresses.
The default range is 100~149. Enter a value for the DHCP server to start with when issuing IP addresses. This
value must be 192.168.1. 2 or greater, because the default IP address for the Router is 192.168.1.1.
Static IP
Static IP Address. If necessary, you can assign a static IP address to a specific computer based on its MAC
address. Complete the
Static IP Address
field.
MAC Address. Enter the MAC address of the specific computer to which you will assign a static IP address.
To add a static IP entry, click the
Add to list
button. To delete a static IP entry, select the listed entry, and click the
Delete selected Entry
button.
