nuget package urls - how to find source

Question

I'm attempting to use nuget on a corporate network. Our security software is blocking the majority of the nuget packages (gives 403 errors).

I'm trying to find out what URL's need to be unblocked to get nuget fully working, but other than our security team scanning our logs to see what I've accessed I'm unable to find out where the packages are actually being hosted.

I can't see anything on nuget.org that helps. Does anyone have any ideas, am I missing something really obvious?

Answer 1

Well the repo is located at https://nuget.org/api/v2/
If that url isn't enough, Fiddler should be of some help.
