#Script written by Eric Jodoin
\ No newline at end of file

Commented out 2 lines that kept throwing an error.
https://gist.github.com/Trumpy/9a1326a2992028a5a8e3

just followed this, i think using the latest script posted by trumpy

got "PolarSSL cert certificate is undefined" from my iphone

its because my Default.txt file needed a line break at the end (Or another script update)

basically <ca> needs to be on its own line in the ovpn file

This is what got me passed the ta.key not found problem. Little weary that the first part of the installation did not do something it should of, but now I have a .ovpn file.

For some reason I did not have a ta.key file in the first place so I ran this

openvpn --genkey --secret /etc/openvpn/easy-rsa/keys

this will create the ta.key...

Using the scripts changes from coolaj86 and running the script from /etc/openvpn/easy-rsa/keys worked.

It created my .ovpn file.

On to the next step, hope that helps...

How would I make this so I am able to use my VPN from any outside network?

I'm getting ta.key not found, this error exactly: [ERROR]: tls-auth Key not found: ta.key

I think in the line 46 a "#" is missing.
