4-Port SSL/IPSec VPN Router

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, 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, RIPv, RIPv, or Both RIP v and v.

Transmit RIP versions

To use dynamic routing for

transmission of network data, select the protocol you want:

None, RIPv, RIPv - Broadcast, or RIPv - 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 4-Port SSL/IPSec VPN

Router.

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 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.

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 switch, PC, or router.

Interface

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.
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 Tables to see the details of your entries. 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, you have

to carefully 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.
