When you are finished, click the Logout link at the upper right corner of the Web Management
Interface or proceed to additional setup and management tasks.
Configuring the WAN Mode (Required for the UTM25’s Dual
WAN Mode)
On the UTM25 only, the dual-WAN ports of the UTM can be configured on a mutually exclusive
basis for either auto-rollover (for increased system reliability) or load balancing (for maximum
bandwidth efficiency), or one port can be disabled.
Auto-Rollover Mode. The selected WAN interface is defined as the primary link and the other
interface is defined as the rollover link. As long as the primary link is up, all traffic is sent over
the primary link. When the primary link goes down, the rollover link is brought up to send the
traffic. When the primary link comes back up, traffic automatically rolls back to the original
primary link.
If you want to use a redundant ISP link for backup purposes, select the WAN port that must act
as the primary link for this mode. Ensure that the backup WAN port has also been configured
and that you configure the WAN Failure Detection Method on the WAN Mode screen to
support auto-rollover.
