Host WCF service from local network to internet

I have created one WCF service using nettcp binding and one client in my local network domain. client can connect that host service on network domain through IP address. Now I want to access that WCF service from outside my local network domain. My PC is connected with internet but not having 开发者_开发问答live IP address. How can I make settings like my service is accessible from internet ?

You'll have to forward the port you're using (the default net.tcp port is 808 as mentioned by @the_ajp) towards the machine that's hosting the service. This can be configured in your router.
