I have updated new firmware today, I want to try new function "OpenVPN".

It doesn't work, I can't find any help on GUI. Please help!

Enable DDNS server. Service Provider is No-IP.com. I got correct IP showed on the no-ip website.

Enable VPN server. I got correct WAN IP Address and Domain Name.

Export Config File. 

Start openvpn on this config file.

The log shows:
