[Openvpn-users] OVPN-Client for windows

Hi,

I like to work with OpenVPN because it is much easier to
install/configure/running on Linux. 
I have spend 8 weeks on testing FreeSWan with no results - it took only 6
hours to set up a running OpenVPN connection. 
My main argument is: OpenVPN needs no Kernel Patches! 

I had to setup a VPN for a customer. For all offices we decided to use
Linux. But i have also to deal with salesmen (real roadwarriors) using
notebooks which are running Win32. These notebooks don't have a permanent
connection to a network (LAN / WAN), so it is not practicable running OVPN
as a service. It is also impossible to tell these users how to start a
VPN-Connection, even if all necessary informations are stored in a
configuration file.

I decided to write a OVPN Win32-Client to make working with OVPN much easier
for users.

1. Goals
- Make OpenVPN usable for 'normal' users
- Give adminisrators a tool
- A frontend for openssl and keyhandling on windows machines

2. Compiler
- OVPN-Client is developed with Delphi 5 -> i.e. Pascal
- OVPN-Client uses a lot of non-standard components, but all are freeware
and well tested

3. Function
- OVPN-Client dials a RAS-Connection via the native RAS API (works with NT,
W2K and XP)
- OVPN-Client starts the VPN-Connection defined as active
- OVPN-Client sets up the routes to the destinations / networks
- OVPN-Client hangs up all connections, if all work is done

4. Security
- On initial startup the program asks for an administrator and guides you
through the configuration
- The admin can define actions on abuse of the client (prevent start up,
mail a warning to the admin - in future maybe more....)
- The user must login with an account and password
- OVPN-Client stores data in the registry. All sensitive data are encrypted
by a strong 448 bit blowfish cipher.

5. Notes
- OVPN-Client is developed unter the GPL Version2
- OVPN-Client is 'weekend-ware'. This meens that i dont't have much time to
develop the program
- Most dialogs and menus are still in german, i started to translate it to
english for international use
- There are no information about it on my website, but i will post some
screenshots today. Informations and download will follow soon. These infos
you will find in the software section on http://www.datasysteme.de

Any suggestion, critic and help is welcome

Bye
Dirk
