Examples of systems and methods are provided for communication and for forwarding display data related to a remote session between a client device and a remote server to a host device. The system may facilitate establishing the remote session with the remote server. The system may facilitate establishing a trusted relationship between the client device and the host device. The system may filter out data related to local graphical user interface (GUI) and selectively forward from the client device to the host device display data related to the remote session established between the client device and the remote server.
