使用INDY开发客户端服务器应用程序

Question

I am currently developing a client server app , but i want to clarify some information about the following.

What must be my idtcpserver binding IP adress (127.0.0.1 ,192.168.1.1 or my public IP)

I checked it using IPconfig it replied me 192.168.1.1 ;but i have connected to the internet using my home adsl router(single port).

I have assigned my client application with

idtcpclient.host := my public IP address

the application is working well when i assign both with 127.0.0.1 // as both are in the local machine

How to make my application work over the internet.When i try to connect over the internet the client is replying me

Socket error #10061 connection refused.

but my kaspersky network monitor is showing that my port is opened my myapplication (I set it to 6000)

original project sourceforge

You don't need to create a binding on the server machine. Just assign the default port. At run time, a single binding will be created with that port and a blank IP address.

When you connect to your network from the outside using the external IP address, you are actually connecting to your router (or other hardware). You should be able to tell your router that traffic received on a specific port will be directed to an internal IP address.

I have a handful of servers running on my internal network, and this is how I make them available from the Internet.

You mention that you have a DLink router. If it works the same as mine:

• Using your favourite web browser, open the router's settings page.
• I think the default address is http://192.168.0.1 . User name is "admin" with no password.
• Click the Advanced tab and select Virtual Server.
• The virtual server settings are pretty straight forward.
