Advanced Configuration

10/100 8-Port VPN Router

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, select

Enabled. 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.

NOTE: Static routing is an advanced feature.

Create these routes with care.

To create a static route entry, enter the following

information:

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 0.

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.

Default Gateway Enter the IP address of the router of the

network, for which this static route is created. For example,

if this network is connected to the local router’s LAN port

through another router, use the WAN IP address of that

router.

Hop Count 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 computer or router.

Interface Select the appropriate interface. The Interface

tells you whether your network is on the LAN, WAN1, or

WAN2/DMZ. If the gateway router is on a LAN port, then

select LAN. If you are connecting to another network

through the Internet, select the appropriate WAN port

option.

Click Add to List, and configure as many entries as you

would like, up to a maximum of 30. To delete an entry,

select it and click Delete selected IP.

Click Show Routing Table to see the details of your

entries.

Routing Table Entry List

Click Refresh to update the on-screen information. Click

Close to exit this screen and return to the Advanced

Routing screen.

On the Advanced Routing screen, click Save Settings

to save your changes, or click Cancel Changes to undo

them.

DHCP > 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 computers 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, do one of

the following:

Configure the IP address, subnet mask, and DNS •

settings of every computer on your network. (Make

sure you do not assign the same IP address to different

computers.)

Set up a stand-alone DHCP server with the Router as •

the default gateway.
