Simple Connect makes it easier to establish a connection when a remote computer is behind some kind of a network address translating (NAT) gateway, such as a home network router or corporate firewall. Without Simple Connect, before such connection can be established, port forwarding needs to be configured on the NAT gateway. This requires some degree of network knowledge or might not even be possible on corporate network. Simple Connect eliminates the need for configuring port forwarding.
Simple Connect relies on Google Talk infrastructure to establish network connections between the Xtralogic RDP client and the remote RDP server. In most cases the connection is established directly between the client and the remote server and the Google Talk infrastructure is used only for the connection negotiation, meaning that the data traffic flows directly without going through the Google Talk servers. In rare cases of complex network configurations the direct connection can’t be negotiated and the data traffic is relayed through the Google Talk servers. Please note that the RDP traffic is encrypted using SSL or standard RDP encryption protocol and is not visible to the Google relay server.
In order to make a server available to Simple Connect, the Xtralogic RDC Companion application has to be installed on the server, configured with Google account email address and password, and logged in. The same Google account has to be used in the Simple Connect settings in the Xtralogic RDP client. Any Google account can be used with Simple Connect.
A prerequisite for using Simple Connect is outgoing network connectivity on the TCP port 5222, which can be verified by using a Google Talk client (e.g. Gtalk app) on both client and server. Another prerequisite is outgoing network connectivity on TCP port 443 (SSL port), which can be verified by connecting to a https://www.google.com URL using a Web browser. Both of this ports are normally allowed even on corporate networks. Since Simple Connect requires the same network connectivity as Google Talk.
Once the Xtralogic RDC Companion is connected to the Google infrastructure, the corresponding entry will appear in the server list in the Xtralogic RDP client connected with the same Google account. This entry will automatically disappear from the list once the Xtralogic RDC Companion is disconnected on the remote computer, unless it is edited and saved, for example to add RDP login name and password. Once saved, it will remain in the list even if Xtralogic RDC Companion is disconnected on the remote computer.
If 2-step verification is configured for a Google account being used with Simple Connect, an application specific password will need to be generated and used with Simple Connect. This is the same as what would need to be done for a standalone Google Talk client.
