Summary
This article explains how to configure Web Interface failover when using Access Gateway 8.0, Enterprise Edition.
Procedure
Even when the appliance is not licensed as a load balancer, it is possible to create a virtual server with one real server bound to it. Multiple real servers cannot be load balanced, but the virtual server can provide health monitoring and failover capabilities. Leverage this capability to implement Web Interface failover in a Secure Gateway replacement scenario.
For example, suppose you have two Web Interface servers on the LAN, configured identically:
• WISRV01: 172.16.100.81
• WISRV02: 172.16.100.82
- Create service entities on the Access Gateway Enterprise Edition appliance that corresponds to the two Web Interface servers:
- Create a load balancing virtual server with only WISRV01 bound to it as a service.
- Create another load balancing virtual server with only WISRV02 bound to it. This virtual server need not be directly addressable.
- Re-edit the properties of the primary Web Interface virtual server, select Advanced, and select the second virtual server as the Backup Virtual Server.
- Now use the primary virtual server instead of a real Web Interface server address when configuring the home page in the global settings or as part of a session policy, for example, http://192.168.0.123/Citrix/AccessPlatform/. All Web Interface traffic will go to WISRV01 by default. If WISRV01 goes down and WISRV02 is alive, then users would automatically fail over to WISRV02.
