Why is the traffic does not go through the VPN connection?
I installed openvpn server on Ubuntu 14 droplet and i'm trying to connect through it on my Fedora 20 home computer.
There is a connection (according to the log below), but my IP didn't change.
ANY IDEA WHY?
I re-install the server several time (tried different distributions) from several guide i found on the internet, and i'm starting to think the problem is with the client and not with the server.
SERVER: UBUNTU 14
CLIENT: FEDORA 20
(I changed the public ip in the logs blow to X.X.X.X)
