Can Connect to OpenVPN but no internet access

Question

I have set up an openvpn server, generated a certificate and downloaded it to my client machine.

After importing the client.ovpn file in the network manager, I can still ssh into the server itself, but cannot access the internet.

In my sever's openvpn server.conf, I have:

 push "redirect-gateway def1 bypass-dhcp"
 push "dhcp-option DNS 208.67.222.222"
 push "dhcp-option DNS 208.67.220.220"

all uncommented.

In the global sysctl.conf file I also have:

net.ipv4.ip_forward=1

Is there anything I am missing configuration wise? What can I do to help debug the problem?

Solution

Needed to add this to /etc/rc.local

iptables -t nat -A POSTROUTING -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j SNAT --to $MY_IP

Which probably would have shown up had I checked out route earlier!

Where can't you access the Internet? On your client or on the server?

Client, the server can access it fine

[Fabby]

Could you give the output to route on the client before and after connecting to the server? Please edit your question to provise this.

To the server's.

Any chance you can explain why we need this on the server side? What does it do?
