When using a tunnel client, the specified user must be “authenticated” by the station before a connection is granted (established). If the user is not found, or if the entered password is incorrect, a popup message appears on the client PC (Figure B.7). Note the User Name and Password are both case-sensitive.

As previously cautioned, note that “basic authentication” is used in any client connection to the station’s TunnelService, with possible security consequences. See Best security practices for tunneling.

Currently, only one tunnel connection is allowed per LonTunnel (or SerialTunnel). If another client application attempts a connection to that tunnel, a popup message appears on that PC (Figure B.8).
