Hello... I don't know how exactly cable modem works, but I think it works like a DSL modem. DSL modem can connect only to a DSLAM. You cannot connect directly DSL modem to DSL modem. That means you must use a good old analog modem (56k modem) or you can use VPN. Just use the VPN function from Windows XP.

hi, i want to transfer the data in my app using codes not using an external app.

Ok... that means you don't know anything about VPN. VPN is an encrypted network in the internet. You must first make a connection using Connection Wizard in Windows XP. Then you can see that Windows XP has created a new network. And you see, that your client and your server got a new IP address. For example : 192.168.0.1 and 192.168.0.2 Then you can send your data (or whatever) through this IP. You can work with your code normally. Your data with automatically encrypted from client to server.

It's quite obvious that you don't know how a cable modem works. You can't use it to "call" another cable modem, or a server for that matter. It will only connect to the cable company service, and supply you with a connection to the Internet. You don't get to tell it where to connect or how. It is mearly a part of the cabling medium that your IP traffic travels over, which your application shouldn't care about at all. The only way you're going to get a secure connection to your server is to have a VPN tunnel setup between your two networks. How you code builds this tunnel is entirely up to the VPN solution your using. There is no support for this in the .NET Framework. Dave Kreskowiak Microsoft MVP - Visual Basic
