Hello I'll have to let IIOP go throught my netfilter gateway I had a look to IIOP, CORBA 2.0 and related doc, and the problem seems to be that iiop embeds ip addresses in its paylod, thus it can't be simply NATed, some protocol analysis has to occur like for example h323 Unfortunately I didn't find some netfilter add-on for iiop Did I miss something or is this feature not available for the moment ? thanks for your answers - * - * - * - * - * - * - Bien sûr que je suis perfectionniste ! Mais ne pourrais-je pas l'être mieux ? Thierry ITTY eMail : Thierry.Itty@xxxxxxxxxxxx FRANCE
