Can a Irule do this 0.0.0.0-->LB-->to one of 2 SNAT Pools

This sounds do-able, I'm not sure of the best way to do the ratio but certainly you can use the snatpool command based on a decision that is made in the iRule logic of when to use each one.

 

 

My first thought is just a loop from 1 to 10 where the first 6 connections are sent to snatpool 1 and the rest to snatpool 2. Someone can probably think of a more efficient way to do that but here goes...

 

 

pseudocode:

 

 

     
    when RULE_INIT {     
    set counter 0     
    }     
     when CLIENT_ACCEPTED {     
         if $counter < 6 {     
           snatpool pool-1     
         } else {     
           snatpool pool-2     
         }  
      increment $counter  (not sure of the best syntax here)      
        if $counter > 9 {     
         set counter 0     
        }     
     }
