NETGEAR UTM5EW-100NAS manual Configure Load Balancing and Optional Protocol Binding, 566

ProSecure Unified Threat Management (UTM) Appliance

Table 145. Failure detection method settings (continued)

Setting	Description
Custom DNS	DNS queries are sent to the specified DNS server.
	DNS Server	The IP address of the DNS server.
Ping	Pings are sent to a server with a public IP address. This server should not reject the
	ping request and should not consider ping traffic to be abusive.
	IP Address	The IP address of the ping server.
Retry Interval is	The retry interval in seconds. The DNS query or ping is sent periodically after every
	test period. The default test period is 30 seconds.
Failover after	The number of failover attempts. The primary WAN interface is considered down
	after the specified number of queries have failed to elicit a reply. The backup
	interface is brought up after this situation has occurred. The failover default is
	four failures.

Note: After the primary interface fails, the default time to roll over is 2 minutes. The minimum test period is 30 seconds, and the minimum number of tests is 4.

Note: You can configure the UTM to generate a WAN status log and email this log to a specified address (see Configure Logging, Alerts, and Event Notifications on page 466).

Configure Load Balancing and Optional Protocol Binding

To use multiple ISP links simultaneously, configure load balancing. In load balancing mode, the DSL interface, USB interface or any WAN interface carries any outbound protocol unless protocol binding is configured.

When a protocol is bound to a particular interface, all outgoing traffic of that protocol is directed to the bound interface. For example, if the HTTPS protocol is bound to the DSL interface and the FTP protocol is bound to the WAN1 interface, then the UTM9S or UTM25S automatically routes all outbound HTTPS traffic from the computers on the LAN through the DSL interface. All outbound FTP traffic is routed through the WAN1 interface.

Protocol binding addresses two issues:

•Segregation of traffic between links that are not of the same speed.

High-volume traffic can be routed through the DSL interface connected to a high-speed link, and low-volume traffic can be routed through a WAN interface connected to a low-speed link.
