Mobile VPN Software Loses the VPN Connection After 5 Minutes on a Vista PC
Posted on 2008-11-18
A Watchguard X20e has been installed and V10.04 of the Mobile VPN Software installed on two laptops; one running XP Pro and the other Vista Business.
The XP Pro laptop establishes the VPN connection and this continues working until the connection is closed. The Vista laptop however, which is virtually an identical model, connects normally but after approximately 5 minutes the connection drops for no apparent reason. If the IP address of the remote server is pinged continuously, then after perhaps 50 'reply from' messages a 'timed out' message appears instead, even though a mapped drive is being accessed at the time.
If the VPN software is re-connected, then everything works for approximately 5 minutes again.
What could be causing this and how can this be resolved? The Firewall is a new X20e model and the VPN software is the current version. Also the same user profile file is being used on both laptops, which also works fine on a third XP Pro PC.
