Maximum number of silmultaneous connections through 2012 R2 Remote Desktop Gateway

Hello,

Is there a maximum number of simultaneous connections through a 2012 R2 Remote Desktop Gateway?

I found a TechNet article that said "For RD Gateway servers that are running on Windows Server 2008 R2 Standard, a maximum of 250 simultaneous connections is supported."

I assume it is the same for windows 2012 R2, but I wanted to raise the question on here to confirm.

Also, if the max is set at 250, does the user receive a particular error, or you just start seeing degrading performance?

Thanks.
