net.tcp: ¿how to consume service from internet?

Question

I am doing probes with a simple WCF application. I have a self host service and the client. I the same computer or in the same LAN I can send message from service to the client and I can send messages from the client to the service (is a duplex communication).

However, I want to be able to consume the service outside the lan, from internet, but if I use my public IP i get the following error: the remote target machine activel refused the connection.

If I do ping to my public IP, all the packages arrive, in my router, in the NAT configuration, I open the ports (net.tcp an mex ports) and I have disabled the firewall of windows XP (I am using a windows XP installed in a virtual machine).

If I want to access to the metadata, in the internet browser I use the following address: http://localhost:7998/ChatHost, then I get the information of the service. If I change "localhost" with 192.168.1.6 which is the dirección of the PC with the service, I can get the metadata too, and I can get it from any computer of the LAN. If I use my public IP instead of localhost then I get the refused connection error.

All the information that I can get from internet to resolve this problem it's open the the port in the firewall. I have disabled the windows xp firewall and I open the port in the router, but this does not resolve my problem.

How can I consume a net.tcp service from internet?

Thanks.
