The problem is that normally the host item contains the host name and 
not the IP address. In my example it contained the IP address because I 
used fixed IP adresses in my Oracle setup. We could check the HOST item 
and use it if it is an IP address.  A name lookup is propbably not worth 
the effort and would not work in most cases (e.g. ethereal running in a 
different setup). I think the normal case (at least for small/medium 
installations)  is for the TNS-Listener to redirect  to another port on 
the same server and David's patch is enough for that.
I will check some more captures tomorrow.
