Configuring Static Route for Routing to

Another Network

In order to extend your Intranet and control traffic flowing directions, you may

connect a router to the ZyXEL Device’s LAN. The router may be used to separate

two department networks. This tutorial shows how to configure a static routing

rule for two network routings.

In the following figure, router

R

is connected to the ZyXEL Device’s LAN.

R

connects to two networks,

N1

(192.168.1.x/24) and

N2

(192.168.10.x/24). If

you want to send traffic from computer

A

(in

N1

network) to computer

B

(in

N2

network), the traffic is sent to the ZyXEL Device’s WAN default gateway by

default. In this case,

B

will never receive the traffic.

You need to specify a static routing rule on the ZyXEL Device to specify

R

as the

router in charge of forwarding traffic to

N2

. In this case, the ZyXEL Device routes

N2

B

N1

A

R

traffic from

A

to

R

and then

R

routes the traffic to

B

.This tutorial uses the

following example IP settings:

To configure a static route to route traffic from

N1

to

N2

:

1

Click

Network Setting

> Routing

. Click

Add New Static Route

.

2

Configure the

Static Route Setup

screen using the following settings:

• Select

Active

.

•

Specify a descriptive name for this routing rule.

• Type

192.168.10.0

and subnet mask

255.255.255.0

for the destination,

N2

.

field.

Click

Apply

. The

screen should display the route you just added.

Now

. You may need to additionally

configure

B

’s firewall settings to allow specific traffic to pass through.

Configuring QoS Queue and Class Setup

This section contains tutorials on how you can configure the QoS screen.

Note: Voice traffic will not be affected by the user-defined QoS settings on the ZyXEL

Device. It always gets the highest priority.

Let’s say you are a team leader of a small sales branch office. You want to

prioritize e-mail traffic because your task includes sending urgent updates to

clients at least twice every hour. You also upload data files (such as logs and e-

mail archives) to the FTP server throughout the day. Your colleagues use the

Internet for research, as well as chat applications for communicating with other

branch offices.

In the following figure, your Internet connection has an upstream transmission

bandwidth of 10,000 kbps. For this example, you want to configure QoS so that e-

mail traffic gets the highest priority with at least 5,000 kbps. You can do the

following:

•

Configure a queue to assign the highest priority queue (7) to e-mail traffic from

the LAN interface, so that e-mail traffic would not get delayed when there is

network congestion.

•

Note the IP address (192.168.1.23 for example) and/or MAC address

(AA:FF:AA:FF:AA:FF for example) of your computer and map it to queue 7.

Note: QoS is applied to traffic flowing out of the ZyXEL Device.

Traffic that does not match this class is assigned a priority queue based on the

internal QoS mapping table on the ZyXEL Device.

Active

. Set your

to 10,000 kbps (or leave this blank to have the

ZyXEL Device automatically determine this figure). Click

Apply

to save your

settings.
