Static Routing
You will need to configure Static Routing if there are multiple routers connected to your network. The static
routing function determines the path data follows over your network. Static routing allows different IP domain
users to access the Internet through this device. This is an advanced feature. Please proceed with caution.
To set up static routing, you should add routing entries in the Router's table that tell the device where to send all
incoming packets. All of your network routers should direct the default route entry to this Router.
Enter the following data to create a static route entry:
1.
Destination IP: 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.
Subnet Mask: 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.
Default Gateway: If this Router is used to connect your network to the Internet, then your gateway IP is the
Router's IP Address. If you have another router handling your network's Internet connection, enter the IP
Address of that router instead.
4.
Hop Count (max. 15): This value gives the number of nodes that a data packet passes through before reaching
its destination. A node is any device on the network, such as switches, PCs, etc.
5.
Interface: (LAN, WAN1, WAN2/DMZ) This setting directs where the static route is going, either to a PC in your
network or to the Internet. If you’re connecting to a network, select
LAN
. If you’re connecting to another
network through the Internet, select
WAN
.
Click
Add to list
to add a route entry or click
Delete Selected IP
to delete the static route entry.
Click the
Save Settings
button to save the Routing settings, click the
Cancel Changes
button to undo your
changes or click the
Show Routing Table
button to view the current routing table.
Clicking the
Show Routing Table
button will open the
Routing Table Entry List
. This will show the routes you
have established, with network information, number of hops for each route, and the type of interface used. Click
the
Refresh
button to update the screen or
Close
to close it.

DHCP Tab - Setup
Setup
The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server
assigns available IP addresses to each computer on your network automatically. If you choose to enable the
DHCP server option, you must configure all of the PCs on your LAN to connect to a DHCP server. (See Appendix G:
Windows Help.)
Enable DHCP Server: Check the box to enable the DHCP Server. If you already have a DHCP server on your
network, leave the box blank.
Dynamic IP
Client Lease Time
: This is the amount of time each network PC will have an IP Address assigned to it before it
dynamically changes. The range is 5 ~ 43,200 Minutes.
Range Start/End
: Enter a starting IP address and ending IP address to make a range to assign dynamic IPs. The
default range is 100~149.
Static IP
The Static IP section of this screen is provided in the event you want the IP Addresses of certain PCs on your
network to remain static. In this event, enter the Static IP Address in the space provided, along with that PC’s
MAC Address.
Click
Add to list
to add a route entry or click
Delete Selected IP
to delete the static route entry.
DNS
For faster access to DNS Servers through the DHCP Server, enter the IP Address of the DNS Servers in the spaces
provided.
WINS
Windows Internet Naming Service (WINS) is a service that turns NetBIOS names to IP addresses. Enter the WINS
IP Address here. If you do not know the WINS, leave it as 0.
Click the
Save Settings
button to save the DHCP settings or click the
Cancel Changes
button to undo the

DHCP Tab - Status
The DHCP Server Status reports the IP of the DHCP Server, the number of Dynamic IP Addresses and Static IP
Addresses Used, DHCP Addresses Available and Total Addresses within the Range set.
The Client Table shows the information related to each PC on the network: Client Host Name, IP Address, MAC
Address, and Leased Time. Click the
Trash Can
icon to terminate the DHCP lease, releasing the IP Address of the
Client Host, or click the
Refresh
button to refresh the Client Table.
System Management Tab - Dual-WAN
Dual-WAN
There are two functions provided for users – Smart Link Backup and Load Balance. If you selected DMZ on the
Setup Tab’s Network screen (shown in Figure 5-5), you will not be able to set up Dual-WAN.
If Smart Link Backup is selected, you will need to choose which WAN port is the primary, leaving the other as
backup. Load Balance automatically manages the Internet connection through both WAN ports.
Network Service Detection
Network Service Detection helps manage your connection and can report when your connection experiences
problems. To utilize this service, select
Enable Network Service Detection
. Select
Remove the Connection
if
you do not wish to utilize this feature.
Retry Count
: If your connection fails, the Router will try to reconnect as many times as you specify in this space.
Retry Timeout
: This shows how many times the router will try to make a connection to your ISP before it times
out.
When Fail
: Should the connection not be reestablished, you can set this to either include this in the system log
(by choosing
Generate the Error Condition in the System Log
) or not.
Network Service Detection can either test this using the Default Gateway by pinging the Default Gateway or by
pinging a specific IP Address for an ISP Host, Remote Host, or DNS Lookup Host

System Management Tab - SNMP
10/100 8-Port VPN Router
System Management Tab - SNMP
SNMP, or Simple Network Management Protocol, is a network protocol that provides network administrators with
the ability to monitor the status of the Router and receive notification of any critical events as they occur on the
network. The Router supports SNMP v1/v2c and all relevant Management Information Base II (MIBII) groups. The
appliance replies to SNMP Get commands for MIBII via any interface and supports a custom MIB for generating
trap messages. See Figure 5-24.
To configure SNMP, enter the necessary information in the following fields:
SNMP Enable
: SNMP is enabled by default. To disable the SNMP agent, click this box to remove the check mark.
System Name
: Set the hostname far the Router.
System Contact
: Enter the name of the network administrator who can be contacted with updates about the
Router.
System Location
: The network administrator's contact information is placed into this field. Enter an E-mail
address, telephone number, or pager number.
Get Community Name
: Create a name, no more than 64 alphanumeric characters in length, for a group or
community of administrators who can view SNMP data. The default value is “Public”.
Set Community Name
: Create a name for a group or community of administrators who can receive SNMP traps,
messages regarding the Router’s status. A name of no more than 64 alphanumeric characters long must be
entered.
Trap Community Name
: Type the Trap Community Name, which is the password sent with each trap to the
SNMP manager. A name of no more than 64 alphanumeric characters long must be entered.
Send SNMP Trap to
: Enter the IP Address or Domain Name in this field where the Router can send traps.
Click the
Save Settings
button to save the SNMP settings or click the
Cancel Changes
button to undo your
changes.
