<div dir="ltr"><div><div><div><div>Hello Torsten,<br><br></div>that is also an issue with the Shrew Soft client. There does not seem to be a reliable watchdog mechanism which checks the availability of the servers behind the VPN tunnel. This is in particular true if the client computer is not used for some time and goes into a power-save mode. Dependent on the particular hardware configuration, this can cause the network connection to be interrupted on a physical level. This causes the VPN to be shut down by the gateway as well. In some situations, Shrew Soft's VPN client does not get aware of that and therefore does not display a "disconnected" state. <br>
<br></div>Only solution which spontaneously comes to my mind is disabling all power save features, at least during the time the VPN is used. I usually also connect my notebook to the power cord every time I use the VPN connection.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">how do you find out that there is no VPN connection? If it is at least possible to access the VPN gateway (refer to the "General" tab in your connection's properties in Access Manager) it is likely that the
connection is established but there may be a problem with routing / tunneling. See also the discussion "Unable to access external sites while VPN is connected" in this mailing list.
