
To configure NAT:
1. Select Network Config > WAN Settings > WAN Mode. The WAN Mode screen
displays (see Figure 304
2. In the NAT (Network Address Translation) section of the screen, select the NAT radio button.
3. Click Apply to save your settings.

Configure Classical Routing

In classical routing mode, the UTM9S performs routing, but without NAT. To gain Internet
access, each PC on your LAN needs to have a valid static Internet IP address.
If your ISP has allocated a number of static 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.
To view the status of the WAN ports, you can view the Router Status screen (see
System Status on page 439).
WARNING!
Changing the WAN mode from NAT to classical routing causes all
LAN WAN and DMZ WAN inbound rules to revert to default
settings.

Configure Auto-Rollover Mode and the Failure Detection
Method
To use a redundant ISP link for backup purposes, ensure that the backup DSL or WAN
interface has already been configured. Then select the DSL or WAN interface that should
function as the primary link for this mode, and configure the WAN failure detection method on
the WAN Mode screen to support auto-rollover.
When the UTM9S is configured in auto-rollover mode, it uses the selected WAN failure
detection method to detect the status of the primary link connection at regular intervals. Link
failure is detected in one of the following ways:
• DNS queries sent to a DNS server
• Ping request sent to an IP address
