We love the Juniper solution.  Works great.

For an open source solution check out SSL-Explorer.  Another nice
product.

        |  Hi Joe,
        |  
        |  My personal experience is with a medium size network 
        |  deployed using OpenVPN on Debian for the servers and 
        |  Windows XP SP2 + OpenVPN GUI for the clients, using 
        |  X.509 certificates (we are our own CA).
        |  
        |  Issues?
        |  None at all.
        |  
        |  Programs that do not work?
        |  None of the programs we use... and we use a lot of stuff.
        |  
        |  Features?
        |  We found the flexibility to direct all traffic 
        |  through the VPN (or not) very useful. We have 2 
        |  config files each, one directs all traffic through 
        |  the VPN, and the other only implements traffic to 
        |  our servers on the other, thus we can decide which 
        |  one to use depending on our needs.
        |  
        |  X.509 certificate authentication is a pain to deploy 
        |  in the very beginning, specially if you've a large 
        |  user population (you've to create a certificate for 
        |  every user), but after that maintenance is close to 
        |  nil, other than creating certificates for new 
        |  starters of issuing a CRL to the servers when 
        |  someone leaves the company.
        |  
        |  We have multiple servers, and the configuration 
        |  files for the clients specify all of them. We had a 
        |  server failure (hard disk crash) and we noticed it 
        |  only when the logs failed to arrive by email. No one 
        |  lost connectivity.
        |  
        |  If you're a part of a company that likes to have a 
        |  big team offering you commercial support for big 
        |  bucks, forget about it ;-) If you want a product 
        |  that WORKS FLAWLESSLY and costs you almost nothing, 
        |  go for it.
        |
