Use

menu 11.5 to specify the filter set(s) to apply to the incoming and outgoing traffic between this remote

node and the Prestige to prevent certain packets from triggering calls. You can specify up to 4 filter sets

separated by commas, e.g., 1, 5, 9, 12, in each filter field. Note that spaces are accepted in this field. For

more information on defining the filters, please refer to the

Filters

chapter. For

PPPoE or PPTP

Encapsulation, you can also specify remote node call filter sets.

Figure 9-7 Traffic Redirect WAN Setup

The following network topology allows you to avoid triangle route security holes when the backup gateway

is connected to the LAN. Use IP alias to configure the LAN into two or three logical networks with the

Prestige itself as the gateway for each LAN network. Put the protected LAN in one subnet (Subnet 1 in the

following figure) and the backup gateway in another subnet (Subnet 2). Configure a LAN to LAN/Prestige

firewall rule that forwards packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).

Figure 9-8 Traffic Redirect LAN Setup

9.5.1 Route Priority and Metric

The metric sets the priority for the Prestige’s routes to the Internet. If any two of the default routes have the

same metric, the Prestige uses the following pre-defined priorities:

1.

Normal route: designated by the ISP or a static route.

Page 109 / 285

9-12

Remote Node Setup

2.

Traffic-redirect route.

3.

Dial-backup route.

For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and

dial-backup route has a metric of "3", then the normal route acts as the primary default route. If the normal

route fails to connect to the Internet, the Prestige tries the traffic-redirect route next. In the same manner,

the Prestige uses the dial-backup route if the traffic-redirect route also fails.

If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal

route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater).

To configure the parameters for traffic redirect, enter 11 from the main menu to display

Menu 11.1—

as shown next.

Active

Press [SPACE BAR] and select Yes (to enable) or No (to disable) traffic

redirect setup. The default is No.

When the Active field is Yes, you must configure every field in this screen

unless you are using PPPoE or PPTP encapsulation (except Check WAN

IP Address and Timeout).

If you don’t configure these fields and are using PPTP or PPPoE

encapsulation, then the Prestige checks the PPPoE channel or PPTP

tunnel to determine if the WAN connection is down.

Configuration:

Backup

Gateway IP

Address

Enter the IP address of your backup gateway in dotted decimal notation.

The Prestige automatically forwards traffic to this IP address if the

Prestige’s Internet connection terminates.

0.0.0.0

Metric

Enter a number from 1 to 15 to set this route’s priority among the

Prestige’s routes (see

Route

) The

smaller the number, the higher priority the route has.
