UPnP(tm) is basically SNMP done with SOAP instead of ASN.1, with some bits = of ZeroConf thrown in for good measure. It involves resource discovery, service discovery and property manipulation. If you're interested, the specification for an "Internet Gateway Device" is= available from the UPnP website. Basically, the IGD allows (authorised) ma= chines to request the gateway to do things such as: - Connect to the internet - report statistics - create a forwarded port The "create a forwarded port" part is used by Remote Assistance as well as = MSN Messenger. These are not things that can be emulated in netfilter - you'll need a SOAP= service, and a whole bunch of other software to implement the IGD specific= ation. Last time I looked, some people had in fact implemented UPnP services for L= inux, but I'm not sure whether IGD was implemented. Regards Alex
