OpenVPN with iOS

Brief history: I upgraded to Cox Gigablast and they included a Netgear R6300v2.  I had a VPN on my previous router (ASUS Dark Knight) that I used for conneting securely in places that aren't secure.  Coffee shops, airports, etc.  

Trying to setup the is OpenVPN vpn on the router and I have it all setup with a DynamicDNS service and everything.  Downloaded Certs and OVPN file and imported into iPhone.  Open up the OpenVPN app and import in the profile.  It gives the following error: "iOS doesn't support TAP-based tunnels"  

In doing research, apparently I have to setup a TUN based vpn so that it will work with IOS.  Is there a way for me to switch this vpn tunnel to a TUN based type?  I can't seem to find a setting for that.  Any help would be greatly appreciated.  Thank you!
