Difficulty creating unified .ovpn file from certs

starlessblack

Netgear recently released a firmware update with smartphone (iOS & Android) support for the built in OpenVPN server. I was able to successfully download and install the .ovpn, ca, client and key certs from my router, onto my iOS devices via the iTunes app file transfer.

What I’ve been unsuccessful with, however, is creating a unified .ovpn file that contains the three certs embedded directly in the .ovpn text. Netgear even provides some guidance on this in the form of a KB article (https://kb.netgear.com/app/answers/detail/a_id/29826/session/L2F2LzEvdGltZS8xNDQ4NzQyODQzL3NpZC9TVlNMZ0ZDbQ%3D%3D), which I used in addition to the OpenVPN iOS FAQ. But when I transfer the unified .ovpn file to the iOS devices, I’m getting a PolarSSL error regarding certificate verification (validation?) failure. Being new to OpenVPN, I’m not sure what this means, but it would almost sound as though OpenVPN is doing some check of my ca.crt against a database of known trusted certificate authorities.

Can anyone shed some light on this for me? Thank you very much.

I guess each post you make on these forums has to be approved by a moderator, so that's why there's a delay in submission to post?

When I download the VPN certs and .ovpn file from the router, there is no OpenVPN static key, and their paltry documentation never makes mention of one, nor does their .ovpn file have any tls-auth or key-direction fields in it. Color me baffled.
