Thanx for your reply. When we connect to the internet by using an ISP, there maybe no valid IP available for the client. In this case how the messenger server can retrieve the client IP automatically in order to be able to make a connection with its client? Can I for example with an Indy HTTP client/server design such client/servers?

Thanx,
