There are two huge benefits that compelled me to use OpenVPN: it doesn't require any kernel modules and it heavily uses SSL crypto infrastructure. The benefit of the lack of kernel module is clear -- it doesn't require constantly trying to patch in a driver when upgrading kernels. A small but annoying hassle. The use of the SSL crypto infrastructure gives me less cause for concern related to whether the encryption has been implemented properly. And a note on performance: I run connectivity to our hosting facility over OpenVPN. One day I was at the facility, directly connected, and I was getting over 2MB/sec before my (older) server ran out of performance. It's been working great for us here at tummy.com -- we've switched all of our VPNs over to use it. -- Sean Reifschneider

I have been testing the first few betas using 'hideit' to hide the console window. It has been working perfectly for me between a win2k machine and my own linux distribution (using kernel 2.4.21 at the moment). I just installed the new version with service support. Once I copied my config file and renamed the extension I startup up the service. What can I say, this new version totally and uterly rocks if you need a windows solution. I have been using openvpn for a year or so now between unix machines (replacing 'cipe') and have found it faultless. It's been simply too good! This new windows version is soo good. Thanks for such a great product. -- Rob

I've been using openVPN since you ported it to windows, and I must say it is fantastic. In just 2 short weeks of testing, I have decided to scrap my IPSec VPN that I have been using for my small business in place of openVPN. One thing that I have found to be immensely useful is the ethernet bridging. I would rather bridge than route for my particular situation, because I want my remote vpn clients to be on the same subnet as the office-bound clients for myriad reasons. I did not like having to manually configure IP addresses for each client, so I elected to use a dhcp server to serve my remote clients an IP address through the openVPN tunnel. -- Dave Lau

OpenVPN's modular design is a winner, in the best tradition of good Unix software. I've begun looking at other alternatives, and this looks like the best to me. -- Rob

I use this outstanding piece of software every day for my 1500-mile telecommute. I appreciate the continued development, especially since my ISP recently decided to block UDP. So far, I've had very good results with the new TCP mode, though of course it is a bit slower. -- Ed

OpenVPN rocks! ... Just wanted to say thanks for OpenVPN and very, very well done! ... The remote DSL ip address changed right after I got this working and I got to see how smoothly OpenVPN handled it. It handled it perfectly and reestablished the connection with the new ip address automatically. All this with free software. Is that neat, or what? ... Also, Samba works great, as does LinNeighborhood, ssh, sftp, and everything else I've thrown through this tunnel... Again, all the thanks go to the OpenVPN developers and user community. This software is a wonderful example of open-source generosity, practicality and professionalism. -- Chuck

Thank you for the incredible software - I have tried a few different things, and this is definitely the most reliable and best performing solution I have seen. -- Mike

Firstly I want to thank you for this wonderfull piece of sofware. OpenVPN is THE universal vpn solution. -- Cyril

PS To the creators of and contributors to the OpenVPN project, I'd like to say I love it! Great work! Let me know if I could be of any help to the project... -- Brett

OpenVPN is an excellent piece of software, and I thank the authors. I now have OpenVPN installed and working perfectly between my office network and my home network, with each VPN server sitting inside of its local network behind a router doing NAT. -- Hugh

The openvpn.net site is a model of clarity -- esp. the How-To! -- Tom

Lastly, congratulations to the Openvpn developers as I think this is a great and highly competitive application. -- Pieter

OpenVpn really is great piece of work. I rarely had something more useful on my computers!!! -- Juergen

I've been testing OpenVPN 1.3.1 (to much success -- thanks for the excellent software, James!) -- Eric

First I would like to mention that I am really happy with openvpn: I use it for VoIP and it works like a charm. -- Francois

First I would like to say I think OpenVPN is great, I replace the aging VPND with OpenVPN and it is so much better! -- Douglas

Hi, I've been using openvpn for about a month now with great success, I have already setup about a dozen VPN connections in various environments. -- Filipe

Once again: GREAT SOFTWARE, thank you James ! -- Goesta

Thanks for the help, openvpn is a great program. -- Jeremy

First, congratulations for the excelent OpenVPN software. OpenVPN is much better and much easier to use than Freeswan and other alternatives. Thank you! -- Daniel
