How to redirect to an ASM class with Irule

There is an existing request to add support for using source IP address/network as one of the filters on an HTTP class. This would allow you to configure your scenario without using an iRule. If you open a case with F5 Support you could get your request attached to the existing feature request.

In the meantime, you can use an iRule like this. The iRule assumes you already have the HTTP class added to the VIP with no filters. By default all traffic is sent to ASM and then the pool on the class or the pool on the VIP. Only requests from 1.1.1.1 are sent directly to my_pool.

 
 when HTTP_CLASS_SELECTED { 
  
     Check if client IP address is 1.1.1.1 
    if {[IP::addr [IP::client_addr] equals 1.1.1.1]}{ 
  
        Disable ASM for this client 
       PLUGIN::disable ASM 
  
        Send request to a different pool than the VIP's default pool 
       pool my_pool 
    } 
 }
