That's helpful; earlier you said "WeatherLink IP".  I dimly remember a
product which is like a USB or serial data logger but where you access
the serial port over TCP.  But a "Weatherlink Live" (WLL) is a known device.

For the  WLL, you need to use the driver that supports it, which is not
the regular Vantage driver that expects to talk the Davis serial
protocol.

Note the comment about same ethernet segment to receive UDP.

I believe that's correct.  I helped someone set up a VP2 with a WLL.

There is also the UDP broadcast, which I think the driver expects:

I recommend understanding how a VP2 and WLL are supposed to work, and
hoping that the interface from the computer to the WLL is the same in
the Vue/WLL case.

I'm guessing that once you use the right driver it will work.
