I am sorry, but having two interfaces configured to the same subnet is
wrong. If you mean that you disable one of either interface, this would
be ok. But it is definitely not sufficient to just "not use" one of
either interface. The IP stack will not care for if you don't use one of
two interfaces - exactly one of two will just always win and the other
will never be used.
    

It's absolutely no problem to have two interfaces in the same subnet as
long as:

+) There is only one route to the subnet
+) The hostid is set correctly

  

9) Run rfcaddr for TCPBEUI
  
      

Note that NetBEUI is currently ot handled by XWLAN, so you would have to
do that with the script feature.
    

I know, but the problem is that the script is run before the WLAN
interface is configured (which I think is OK). And rfcaddr.exe should be
run afterwards.
