Configuring the WSM using Device Manager

Using HTTP Health Checks

For those firewalls that do not permit ICMP pings to pass through, WSMs can be configured to perform HTTP health checks, as described below.

1. Set the health check type to HTTP instead of ICMP. See Configuring a health check for a real server group.
2. Configure a "dummy" redirection filter as the last filter (after the redirect all filter) to force the HTTP health checks to activate. For more information, see Creating a new filter. Use the settings in the following table.  
   
   

   Field in Device Manager	WSM setting
   Index	224
   Name	FWLB Redirect
   Filter	Enabled
   Action	Redirect
   Proto	tcp
   Redirection Port	80
   Redirection Group	1

   
     
   
   

   Note: Make sure that the number of each real filter is lower than the number of the "dummy" redirect filter.
