My remote users connect to the corporate office using WatchGuard VPN Client on Windows XP. In the corporate office is a FireBox X Edge X55e.
Most of the time, clients can connect and use the FireBox to connect remotely to their desktops using Remote Desktop Connection. On enough occasions to warrant this post, however, the connection drops without warning in the middle of their session. There does not seem to be any particular task they are doing, they just loose connectivity. The way they know this is not that WatchGuard produces an error, but simply that there Remote Desktop ends the session with the standard, "The computer can't connect to the remote computer" message from Remote Desktop.
Besides that, the WatchGuard monitor in the tooltray, and the WatchGuard monitor screen still indicates a connection is established and active (Green Light!).
In order for the user to get "back in". They must click the "Disconnect" button, and then click the "Connect" button again. This will re-establish the connection, and they can work again. A few minutes later, the same thing happens.
There are some errors in the log such as:
"iked Received a packet from an unknown SA"
"kernel checkout_cb: freelist exhausted"
Since this is intermittent, it's very hard to track. Is anyone else having this problem?
