Good, happy to know it works for you. 
But something was bothering me so I did a sanity check.
The firmware for WR302N above does include only luci-app-openvpn (the webinterface for openvpn, which is of course useless alone), but NOT openvpn (the actual program doing the work).
It seems the luci-app-openvpn package I selected does not have openvpn in its dependencies (kinda weird), so openvpn was not integrated.
I tried to integrate it now, and as I was suspecting, the only way to fit openvpn in there is to not install luci webinterface nor any other additional package.
This is the command I used this time.
make image PROFILE="tl-wr802n-v1" PACKAGES=" openvpn-mbedtls"
This is the link to the firmware image that has openvpn but has no luci. http://dl.dropboxusercontent.com/u/47541136/LINUX/LEDE/lede-ar71xx-generic-tl-wr802n-v1-squashfs-sysupgrade-openvpn.bin
