We ran into an issue trying to use a W2K8 server as a 'bridgehead' to install RUT hosts onto PC's in a network. All running 220.127.116.11.
Windows 7 PC Viewer to W2K8 host. Host running portable viewer connecting to Windows 8 host PC on servers LAN to push out installation. When we tried to use this config we found that the keyboard Caps would not work (try for F, shows f, etc) Caps working on Windows 8 host when direct connect from Windows 7 viewer (bypassing W2k8 host). Caps also worked when using RDP from W2K8 server while using RUT to server.
