[Solved] NordVPN installed and running however still no internet access?!

I will just start off by saying that I am a bit of an amateur here - so apologies in advance if I've missed something small. Let me explain my setup first:

I have a small Ubuntu 14.04 server connected to a wireless access point (running in bridged mode), which in turn is connected to the main router downstairs - not sure if this has an impact on what I'm doing but thought it was worth mentioning. I have also recently purchased a subscription for NordVPN so this is the provider I'm using.

I have installed the OpenVPN package, downloaded the config files from NordVPN and attempted to connect to a VPN server using the few steps outlined here: https://nordvpn.com/tutorials/linux/openvpn/

After entering my username and password I see the following output:

Code: Select all

It seems that I can connect to the VPN server just fine - however after running the following command to check my IP I get nothing back:

Code: Select all

curl -s checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//'
Also if I try to ping google.com, I get nothing back - it seems as though I am unable to access the internet while connected to the VPN.

I don't believe I have a firewall setup, here are my FW rules:

Code: Select all

xxx@xxx:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     all  --  anywhere             anywhere            

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
And here is the output from ifconfig while connected to the VPN:

Any ideas what I am doing wrong here, I'm stuck?

Thanks in advance and happy to provide further details :)

You connect to NordeVPN server from your pc at home and your log shows the connection is good.

If you cannot access the internet over the VPN then you must contact NordeVPN ..

I am able to connect to NordVPN from my Mac/iOS device so I believe the issue lies with my linux configuration. As I am not too experienced in this area I wanted to see what my potential problems could be - firewall? the fact that I'm behind a router that is in bridged mode? etc.

NordVPN do not provide any support and I was hoping that someone could point me in a direction because I'm not really sure what to do next

Then demand your money back!

This Forum does not provide free support for paid (or free) VPN Providers.
They take your money then they provide support!

However, due to my unerring generosity .. see this link:

You make some good points - had your advice failed I most likely would have tried Nord.

Nevertheless thank you very much this fixed my issue. I appreciate your help!
