Configuring Web Interface Failover

You can use the Published Applications Wizard to configure NetScaler Gateway to fail over to a secondary server running the Web Interface.

Web Interface failover allows user connections to stay active if the primary Web Interface fails. When you configure failover, you define a new IP address in addition to the system IP address, mapped IP address, or virtual server IP address. The new IP address must be on the same subnet as the system or mapped IP address.

When you configure Web Interface failover on NetScaler Gateway, any network traffic that is sent to the new IP address is relayed to the primary Web Interface. The virtual server that you select in the Published Applications wizard serves as the network address translation (NAT) IP address. The real IP address is that of the Web Interface. If the primary Web Interface fails, network traffic is sent to the secondary Web Interface.
