Hi I know very little about VPNs 1

Hi

I know very little about VPNs. I have to write a software that runs on a client machine and establishes a vpn connection with vpn server. Can any body help me?

Thanks.

Please don't take this the wrong way. But you may want to take a class or purchase a good book on VPN's. Your question is so broad as to be practically un-answerable. You need to narrow the scope of your question.

For instance, what VPN protocol? The popular ones are PPTP and IPsec. There are others too like L2TP. What kind of network configuration do you have. Is your client connecting via dialup, broadband, etc? Also is there some router or NAT device between the client and the host? What about on the server side? What VPN applications are you using? Who is the vendor?

Sorry if I sound sarcastic or anything. I mean no disrespect. But the topic of VPN is very broad as you can probably see.

Hi MaxPipeLine,

Thankyou for responding. At Present I am reading VPN, Chapter 9 in MSDN Technet. That is being helpful.

we are planning to use IPSec. We have wireless network. we are going to use NAT device between server and client. In windows 2000 and NT we can directly give IP Address of server and establish vpn connection through wizards. We want to do all that programmatically, possibly in Visual C++. is this making any sence to you? I don't want code for my problem. I want some guidence in this. It'll be great if somebody could guide me.

Thanks,
Lchig

I am being curious here but yhy do you need to program it? The VPN concentrators will do all of that for you. If you want to open up a secure tunnel from one piece of software to something else then think about tunneling through SSH instead. Again, it will remove a layer of complexity that really you should not need to worry about.

Since you are on the subject, maybe you can help. Up front I admit to being a vpn novice. To explain my hardware:

Machine 1 - win2kpro on a cable connection
Machine 2 - win98se on a dial up connection

Using machine 2, I can get a vpn session or link to machine 1. However, I don't know what should happen next. Should I be running some vpn software on machine 1 that looks for a vpn client and offers a login in script, etc? Or, should the vpn client machine 2 have access to machine 1's files and folders? Just like another machine on the lan?
