iRule snat to certain pool member

Hello,

 

I have a VIP that load balances to two pool members: poolA and poolB. PoolA takes priority, but if and when traffic gets load balance to poolB, it needs to use a snat of 192.168.1.1. How can I write an iRule to make this work?

    try this:

    when LB_SELECTED { 
   if {[IP::addr "[LB::server addr]" equals "1.2.3.4"]} { 
      snat automap
   }
}

    when LB_SELECTED { 
    set poolBaddr "4.3.2.1"
    set snatAddr "1.2.3.4"
   if {[IP::addr "[LB::server addr]" equals $poolBaddr]} { 
      snat $snatAddr
   }
   unset poolBaddr
   unset snatAddr
}
