An Artifactory Virtual Repository aggregates packages from both local and remote repositories.
This allows you to access both locally-hosted NuGet Symbol packages and remote-proxied NuGet Symbol files from a single URL that is defined for the virtual repository.
To create a virtual NuGet repository:
In the Administration module, under Repositories | Repositories | Virtual, Click New Virtual Repository and set NuGet to be its Package Type.
Select the underlying local and remote NuGet Symbol repositories to include under the Repositories section.
