Source Base Routing

I was wondering if anyone has ever done source base routing with an iRule? I have 2 separate frontside networks and 2 separate backside networks and we are trying to keep all the traffic separate. So ...

define a pool for your two gateways, say gw-pool, then create a 0.0.0.0/0 virtual server applied to your internal vlans only and apply this rule to the vip:


when CLIENT_ACCEPTED {
  if { [IP::addr [IP::client_addr]/24 equals 10.223.34.0] } {
    pool gw-pool member 10.223.32.1
  } elseif { [IP::addr [IP::client_addr]/24 equals 10.236.36.0] } {
      pool gw-pool member 10.223.36.1
  } else {
      Your other conditions, if necessary
  }
}

You could use the node command instead of the pool, but then you don't get the benefit of your gateway being monitored (assuming you apply one in your pool definition)
