Does Google Universal Analytics support x-forwarded-for header for ip filters?

Does Google Universal Analytics support x-forwarded-for header for ip filters?

I am trying to filter out internal ips but it doesn't seem to work. The application is sitting behind a proxy, so the client's ip is in the x-forwarded header.

I haven't actually tested this solution yet, but I'm working on it.

It seems like you should be able to do something like this:

import ua from 'universal-analytics'
import publicIp from 'public-ip'

const user = ua(GOOGLE_ANALYTICS_ID)

const uip = await publicIp.v4()
user.set('uip', uip)

After that, you have set the users IP for all coming events and page views.

According to this question the measurement protocol (which forms the base for all versions of the Google Analytics tracking) ignores x-forwarded ip headers.

This is solved in serverside implementations as Google has added a parameter uip (must be a valid IP, will always be anonymized by setting the last three numbers to 000) to the measurement protocol to send a clients ip. I don't know terribly much about proxy servers, but it might be possible to stitch the parameter into the request instead of using a header field.
