Hi @christian_panten_6482,
You would just push the snupkg the same way, but only push the snupkg. For example:
nuget push -source sources-feed MyPackage.1.2.0.snupkg
I also wanted to point out this from our documentation as well:
To summarize, push only the symbol package to your ProGet feed if you intend to use the symbol server. To prevent symbols from being downloaded with the NuGet package, see the Strip symbol files from packages downloaded from this feed option on the Manage Feed page under Symbol Server settings.
Thanks,
Rich
