I have a URL, a username, and a password. I want to establish a VPN connection in C# .Net WinForms.
Can you please tell me from where I can get started? Any third party API's ?
Code samples will be highly appreciated...
To create your own VPN for personal use, you have a few specific hosting options: Run the software on a cloud virtual private server. All cloud providers, from titans like Amazon Web Services to smaller operations like Vultr, offer cloud-hosted servers called VPSs.
iOS devices natively support the L2TP, IPSec, and IKEv2 protocols. To configure a VPN on your iPhone or iPad, go to: Settings > General > VPN > Add VPN Configuration > Type. Here you can select IKEv2, IPSec (by itself), or L2TP (which includes IPSec encryption, even though it doesn't say so).
Placing a VPN server in front of the firewall can lead to greater security in some cases. Remember that a VPN allows users who are external to the network to feel like they are sitting on a machine inside the network.
You can launch external application like in this sample. This probably is easiest way to do it, but it depends on external applications.
Or you can try to use Windows API with some wrapper like DotRas. This could be a bit harder, but you won't have any dependancies on particular external apps.
You can use the rasdial executable to accomplish this:
System.Diagnostics.Process.Start("rasdial.exe", "VPNConnectionName VPNUsername VPNPassword");
Rasdial is Windows 7.. from memory its RasPhone for XP.
