Hallo.
Sorry for my bad english.
I've set up a vpn with openvpn.
One server linux and one client.
It works very well.
Now I have another server to connect to and I want to do this by using
vpn too.
The same client must connect to server1 and to server2.
How can I do this?
With my CA I have to generate the second server certificate anche copy
it to server2?
I must generate also Diffie Hellman parameteres with the second
certificate?
Thank you.
