VPN is typically implemented on your network equipment, not on an individual server. VPN connects you to a network. Once you are connected to your internal network, you simply use ssh (e.g. the Putty client for Windows) to ssh into your HP-UX server.
It might help if you described the problem which you are trying to solve, instead of asking how to implement some particular (vaguely described) "solution".
what I want do is connect to my remote servers from my home place, but I want a secure connection , I have listen about using VPN will be a safe way but I have not information , so I am looking for ideas to try implement this solution.
this all has to be done on the network side . your work is only to connect to the server by using ssh or telnet than give your userid and provide you password using your RSA token .
All things excellent are as difficult as they are rare
As it was mentioned, VPN in general is a complex solution based on special network equipment. With ssh you can get the data flow encrypted without bothering with the complexity of VPN. But here is a link what explains the difference between ssh and VPN:
