We have a Site to Site VPN (HUB) which runs between NY (MX100) and China (MX84). I can use Remote Desktop Connection from China to directly connect to any server or workstation on the NY network. We also have a remote access gateway configured which we access from a webpage. We can connect to the RDS gateway and receive the RDS desktop with the published apps, but when we attempt to run any of the apps, the launching fails. I checked the site to site VPN config (below) an all ports appear to be open. Any guidance would be appreciated. thank you.
