Setting up IP routing load balancing between clients and virtual servers
Setting up SNAT (Secure Network Address Translation) allows you to provide load balancing for client and virtual server connections, even if the IP routing load balancing is not set as the default route. Without SNAT, you run the risk of communications disruptions if TCP connections bypass the load balancing system.
About this task
The easiest way to enable SNAT is by using the SNAT automap, which routes traffic through the virtual server's Self-IP address. Only 64,000 ports can be open at one time when you use a SNAT automap, so this technique is recommended for small- to medium-sized enterprises. If you need more than 64,000 ports open at a time, create a SNAT pool instead.
Complete this procedure using the steps suitable for the IP routing load balancer product that you are using. These are sample instructions.
Procedure
What to do next
Apply the SNAT pool to the virtual server as you would a SNAT automap.
