Section 5 - Connect to the Internet
Auto-Rollover using WAN IP
In this mode one of your WAN ports is assigned as the primary internet link for all internet trac and the
secondary WAN port is used for redundancy in case the primary link goes down for any reason. Both WAN ports
(primary and secondary) must be congured to connect to the respective ISP’s before enabling this feature. The
secondary WAN port will remain unconnected until a failure is detected on the primary link (either port can be
assigned as the primary). In the event of a failure on the primary port, all internet trac will be rolled over to
the backup port. When congured in Auto-Failover mode, the link status of the primary WAN port is checked at
regular intervals as dened by the failure detection settings.
Field Description
WAN Mode Select Auto-Rollover Using WAN IP from the drop-down menu.
Use Primary WAN Port Select which WAN port is the primary.
Use Secondary WAN Port Select which port to use if the primary port fails.
WAN Health Check
• DNS lookup using WAN DNS Servers: DNS Lookup of the DNS Servers of the primary link is used to
detect primary WAN connectivity.
• DNS lookup using DNS Servers: DNS Lookup of the custom DNS Servers can be specied to check the
connectivity of the primary link.
• Ping these IP addresses: These IP’s will be pinged at regular intervals to check the connectivity of the
primary link.
• Retry Interval is: The number tells the router how often it should run the above congured failure
detection method.
• Failover after: This sets the number of retries after which failover is initiated.
WAN1/WAN2/WAN3 Enter the DNS server or IP address to ping.
Retry Interval Enter the time in seconds to initiate the WAN health check. Default is every 30 seconds.
Failover After Enter the number of failures before the router will enable the failover process.
Note: The DSR series routers support 3G USB Modem as a failover link when the internet access is lost.
