Hey All,

I just wanted to give you an update on the issue. I did some digging and found a way of using an iRule to accomplish the required effect. On my catch all forward VIP I added the following iRule 

 
when LB_SELECTED { 
  set public_ip 192.168.1.176  

  if { [IP::addr [IP::client_addr] equals 192.168.3.0/24]  
      && not [IP::addr [IP::local_addr] equals 192.168.0.0/16]} {

    snat $public_ip
  } elseif { [IP::addr [IP::client_addr] equals 192.168.4.0/24]  
      && not [IP::addr [IP::local_addr] equals 192.168.0.0/16]} {
     
    snat $public_ip
  } else {
    forward
  }
}

Thanks
