ProSafe VPN Firewall 200 FVX538 Reference Manual If your ISP has allocated many IP addresses to you, and you have assigned one of these addresses to each PC, you can choose Classical Routing. Or, you can use Classical Routing for routing private IP addresses within a campus environment. Otherwise, selecting this method will not allow Internet access through this Router. To learn the status of the WAN ports, you can view the Router Status page (see "Viewing Router Configuration and System Status" on page 6-23) or look at the LEDs on the front panel (see "Router Front Panel" on page 1-6). Setting Up Auto-Rollover Mode If you want to use a redundant ISP link for backup purposes, ensure that the backup WAN port has already been configured. Then you select the WAN port that will act as the primary link for this mode and configure the WAN Failure Detection Method to support Auto-Rollover. When the router is configured in Auto-Rollover Mode, the router uses the WAN Failure Detection Method to check the connection of the primary link at regular intervals to detect router status. Link failure is detected in one of the following ways: • By using DNS queries to a DNS server, or • By a Ping to an IP address. For each WAN interface, DNS queries or Ping requests are sent to the specified IP address. If replies are not received, the corresponding WAN interface is considered down. To configure the dual WAN ports for Auto-Rollover 1. Select Network Configuration from the primary menu and WAN Mode from the secondary menu. The WAN Mode screen will display. 2. In the Port Mode section, check the Auto-Rollover Using WAN port radio box. 3. Selection the WAN port that will act as the primary link for this mode from the pull-down menu. 4. From the WAN Failure detection Method section, select the detection failure method radio box from one of the following choices: • DNS lookup using configured DNS Servers (ISP DNS Servers) - In this case, DNS queries are sent to the DNS server configured on the WAN ISP pages (see "Configuring the Internet Connections to Your ISPs" on page 2-2). • DNS lookup using this DNS Server (for example, a public DNS Server) - Enter any public DNS server. DNS queries are sent to this server through the WAN interface being monitored. Connecting the FVX538 to the Internet v1.0, August 2006 2-11

v1.0, August 2006

If your ISP has allocated many IP addresses to you, and you have assigned one of these

addresses to each PC, you can choose Classical Routing. Or, you can use Classical Routing for

routing private IP addresses within a campus environment. Otherwise, selecting this method

will not allow Internet access through this Router.

To learn the status of the WAN ports, you can view the Router Status page (see

“Viewing Router

Configuration and System Status” on page 6-23

) or look at the LEDs on the front panel (see

“Router Front Panel” on page 1-6

Setting Up Auto-Rollover Mode

If you want to use a redundant ISP link for backup purposes, ensure that the backup WAN port has

already been configured. Then you select the WAN port that will act as the primary link for this

mode and configure the

WAN Failure Detection Method

to support Auto-Rollover.

When the router is configured in Auto-Rollover Mode, the router uses the

WAN Failure

Detection Method

to check the connection of the primary link at regular intervals to detect router

status. Link failure is detected in one of the following ways:

•

By using DNS queries to a DNS server, or

•

By a Ping to an IP address.

For each WAN interface, DNS queries or Ping requests are sent to the specified IP address. If

replies are not received, the corresponding WAN interface is considered down.

To configure the dual WAN ports for Auto-Rollover

Select

Network Configuration

from the primary menu and

WAN Mode

from the secondary

menu. The WAN Mode screen will display.

In the

Port Mode

section, check the

Auto-Rollover Using WAN port

radio box.

Selection the WAN port that will act as the primary link for this mode from the pull-down

menu.

From the

WAN Failure detection Method

section, select the detection failure method radio

box from one of the following choices:

•

DNS lookup using configured DNS Servers (ISP DNS Servers)

– In this case, DNS

queries are sent to the DNS server configured on the WAN ISP pages (see

“Configuring

the Internet Connections to Your ISPs” on page 2-2

•

DNS lookup using this DNS Server

(for example, a public DNS Server) – Enter any

public DNS server. DNS queries are sent to this server through the WAN interface being

monitored.
