Hello, 

I've been trying to setup OpenVPN for several days now. I've tried Ubuntu and CentOS, neither of which seem to work even when following multiple guides to a T. 

Here is status 

Code

Any help would be much appreciated, thanks in advance

I had a similar problem with my VPN's but i used SoftEther, since im not sure what could cause that problem i suggest trying to enable TUN/TAP.
If that doesn't help, try installing SoftEther and provide me results, you can connect with OpenVPN client to SoftEther one too.

Thanks for your reply. 

I've already tried to enable TUN/TAP but I don't think it's done anything for me. Let me make sure I did it again after my last start-over.

I get this error when trying to modprobe tun

modprobe: ERROR: ../libkmod/libkmod.c:514 lookup_builtin_file() could not open builtin file '/lib/modules/2.6.32-042stab123.1/modules.builtin.bin'
modprobe: FATAL: Module tun not found in directory /lib/modules/2.6.32-042stab123.1

After following some instructions from a Linode forum post, it seems I was able to enable tun0. However, I'm still getting this error when starting the OpenVPN service.

have you tried turning it off and on again?
