OK, at the end what shall we do in order to go from client to server and vice versa, shall we use http telnet or what?
I am still confused, after installing the server and the clients side how to use the openvpn?
In fact i want to connect a centos (server) and a windows xp (client) same as what you did, but in my case, both server and client use modem adsl. So the problem is that they use a dhcp in order to get their IP address, so which IP address should i put in the server/client configuration files?
Thanks a lot again for your pdf, it's very helpfull.
