All connections lost when connecting to OpenVPN server

Question

What I have:

• OSX/PC
• VDS (ubuntu server)
• VPN provider account

What I did:

• Installed openvpn on VDS.
• Successfully connected from PC to VDS server.
• Successfully connected from VDS to VPN provider with my login/password.
• Lost all connections.

Why did this happen? What should I do? I read something about routes and iptable rules, but I can't make sense of it.

Here are my confs:

PC/OSX client.conf:
