Disable port translation in an iRule, or "node" usage

Hi,

I'm trying to create a VIP that handles HTTP, HTTPS and a TCP port range.

I was hoping to create a "wildcard" VIP, then pick pools based on an iRule.

Port 80 and 443 requests go to the port 80 pool, the 20200-20272 pool, preserving the requested port

The problem I'm having is the "node" command is doing what I expect. Requests are still going to port 80 on the pool members.

Is there a way to disable port translation with an iRule?

See something else wrong with what I'm trying? Wrong event maybe?

b rule lvstrn-pools '{
   when CLIENT_ACCEPTED {
      set DEBUG 1
      switch -regexp [TCP::local_port] {
        "80" {
           if {$DEBUG} {log local0. "Port 80 request"}
           SSL::disable clientside
           pool lvstrn.80
        }
        "443" {
           if {$DEBUG} {log local0. "Port 443 request"}
           pool lvstrn.80
        }
        "202[00-72]" {
           SSL::disable clientside
           pool lvstrn.80
        }
        default {
           reject
        }
      }
   }
   when LB_SELECTED  {
      set DEBUG 1
      switch -regexp [TCP::local_port] {
        "202[00-72]" {
           scan [LB::server addr] {%[^%]%%%s} server_ip rdomain
           if {$DEBUG} {log local0. "LB server $server_ip selected for port [TCP::local_port] "}
           node $server_ip [TCP::local_port]
        }
      }
   }
}'  

Thanks!

Ben
