"Do not forget to update your VPN site to get new settings from gateway."
We've recently started to look at this, wanting to extended from 480 to 720, as we find our clients just get forcibly disconnected after 8 hours, even in while the connection is in use, such as an RDP session.
What did you mean by update the VPN site? Do you mean the site configured at the client side? I assume that a disconnect/reconnect would pick up the new timeout settings once the policy has been pushed.
EDIT: Never mind, I just saw the reply from PhoneBoy. 😉
