Network.useNat only available in Js?

Am I missing something or does Network.useNat only work with Js? I’m learning networking and find it weird that I cant seem to find it. Am I not importing something or is it just not there? And if so, why can’t I use C#?

Turns out useNat is obsolete and you now need to set it when calling the InitializeServer function. Just thought I’d give everyone a heads up if you’re using C# as there are no editor warnings when using C#, only Unityscript
