OpenVPN on iPhone fails to import profile for NightHawk R700P

I had the same issue and i was finally able to solve it. I dont know what netgear thinks happens when you follow their normal steps, but it didnt work for me.

I had the issue where it couldnt find these files ca.crt, client.crt, client.key. My solution was to create a "unified" ovpn file. The unified file just means that you embed the contents of ca.crt, client.crt, client.key into the ovpn file, rather than have the ovpn file point to separarte files. 

This page explains how to do that https://openvpn.net/faq/i-am-having-trouble-importing-my-ovpn-file/

One issue I ran into is I found this sample file as an example to follow https://gist.github.com/renatolfc/f6c9e2a5bd6503005676 . That file is wrong. there shouldn't be any [inline] things:

ca [inline]
cert [inline]
key [inline]
tls-auth [inline] 1

my client_unified.ovpn file looks like this

client
dev tun
proto udp
remote {{domain_name}} {{port}}
resolv-retry infinite
nobind
persist-key
persist-tun
cipher AES-128-CBC
comp-lzo
verb 5

<ca>

{{contents_of_ca.crt}}

</ca>

<cert>

{{contents_of_client.cert}}

</cert>

<key>

{{contents_of_client.key}}

</key>

hope this helps!
