I currently have an RDS 2012 Farm deployed in Session-Host Mode with a server for the RD Connection Broker server, and a separate server with the RD Web + RD Gateway roles, and separate servers for the RD Session Hosts. Our RDS Farm deployment is set to use an RD Gateway with “Bypass RD Gateway for local addresses”. We need this, as we have some users accessing our RDS Farm externally through RD Web access using RD Gateway outside of our LAN.
All of our Windows 7-Windows 10 machines and their RDP clients respect the “Bypass RD Gateway for local addresses” setting, but our Wyse C10LE and Dell Wyse 3010 (T10) devices do not bypass the RD Gateway when inside the local LAN. They are set up in VDI mode, and use a Connection Broker entry instead of direct RDP connections. They can resolve the DNS of the RD Session Host and reach port 3389 directly. These are the only two criteria that “Bypass RD Gateway for local addresses” checks for. The thin clients are running ThinOS firmware version “8.3_011”.
I have searched for hours for any settings I may have missed in the WNOS.ini file that would cause the Wyse thin clients ignore the “Bypass RD Gateway for local addresses” setting passed from the RD Connection Broker. I cannot find anyone else who has solved this on the Microsoft forums, or elsewhere.
Does anyone have any insight on this?
