Using node or pool to change the destination port?

I got back to testing this today and think I'm stuck. I'd like to use LTM's pool member selection to pick a pool member, but then change the destination port based on the clientside port requested. To do this, I was hoping to be able to use the node command in LB_SELECTED. However, mgabaldon and testing both indicate you can't do this in LB_SELECTED.

 

 

Is there a way of modifying the destination port in LB_SELECTED or would I have to do the pool member selection on my own prior to LB_SELECTED?

 

 

Thanks,
