WINS server (optional) Lease time (minutes) Relay gateway Allow ping from LAN DNS Proxy Save Cancel DBG-2000 User Guide Enter the WINS IP address in the DHCP configuration. A WINS (Windows Internet Naming Service Server) is the equivalent of a DNS server but uses the NetBIOS protocol to resolve hostnames. It is an optional field. Enter the duration (in minutes) for which IP addresses will be leased to clients. Enter the relay gateway IP address. This field is available when you select DHCP mode as DHCP relay. If this option is disabled, the ping requests to the LAN interface are blocked. When the DNS Proxy field is enabled, the gateway acts as a proxy for all DNS requests and communicates with the ISP's DNS servers. This field is available when you select DHC P relay or None as the DHCP mode. Click Save to save your settings. Click Cancel to revert to the previous settings. WAN Mode Configuration The Nuclias cloud gateway supports multiple WAN links. This allows you to take advantage of rollover and load balancing features to ensure that certain Internet-dependent services are prioritized in the event of unstable WAN connectivity on one of the ports. To use Auto-rollover or Load Balancing, you must configure WAN link failure detection. This involves accessing DNS servers on the Internet or ping to an Internet address (user-defined). In load balancing, you can also select None to disable the failure detection feature. When the failure detection is enabled, specify the retry interval and the number of attempts it has to connect to the configured server. If all the attempts are failed, the WAN port is considered to be down. This section discusses the following WAN modes: Primary WAN Auto-rollover using WAN Load Balancing Round Robin Spillover mode Primary WAN If you do not want to use Auto-rollover or Load balancing, select Primary WAN as the WAN mode and select the WAN port you want to set as the primary WAN port. Auto-rollover using WAN In the Auto-rollover using WAN mode, one of the WAN ports is assigned as the primary Internet link for all the Internet traffic; the secondary WAN port is used for redundancy if the primary link goes down for any reason. Both WAN ports (primary and secondary) must be configured 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). If a failure occurs on the primary port, the Internet traffic will roll over to the backup port. When configured in Auto-rollover mode, the link status of the primary WAN port is checked at regular intervals as defined by the failure detection settings. 52

Auto-rollover using WAN
In the Auto-rollover using WAN mode, one of the WAN ports is assigned as the primary Internet link for all the Internet traffic; the secondary WAN
port is used for redundancy if the primary link goes down for any reason. Both WAN ports (primary and secondary) must be configured 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). If a failure occurs on the primary port, the Internet traffic will roll over to the backup port. When
configured in Auto-rollover mode, the link status of the primary WAN port is checked at regular intervals as defined by the failure detection
settings.
