I doubt you have read the howto.
And I doubt you really understand how to do your job, which I why you come here looking for help.
There are a couple of volunteers here who help people who are having problems with openvpn.
But your problem is not with openvpn, it is that you have not read the documentation and you want
somebody to tell you howto for free.
Nobody likes to help those who clearly have not tried to help themselves.
Soo .. good luck to you.
If you need professional assistance then my email is above.
Or you can seek that assistance via what-ever standard channels the company you work for provide.
