NETGEAR STM150EW-100NAS, UTM5EW-100NAS manual Ping

ProSecure Unified Threat Management (UTM) Appliance

Table 17. Failure detection method settings (continued)

Setting	Description
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 WAN 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 (Multiple WAN Port Models)

To use multiple ISP links simultaneously, configure load balancing. In load balancing mode, any WAN port carries any outbound protocol unless protocol binding is configured.

When a protocol is bound to a particular WAN port, all outgoing traffic of that protocol is directed to the bound WAN port. For example, if the HTTPS protocol is bound to the WAN1 port and the FTP protocol is bound to the WAN2 port, then the UTM automatically routes all outbound HTTPS traffic from the computers on the LAN through the WAN1 port. All outbound FTP traffic is routed through the WAN2 port.

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

•Continuity of source IP address for secure connections.

Some services, particularly HTTPS, cease to respond when a client’s source IP address changes shortly after a session has been established.
