I had problems setting this up, and those settings were given to me by Draytek support and worked for me.

So what is happening now? What is the status of the WAN2 port?

I am not sure what you mean about passthrough the external IP?

Those settings above are to allow you to use your modem for internet access via the WAN2 port. Do those settings not work?

What am I missing here?
