If anyone has ever encountered anything like this or has any ideas please let me know. My VPN services will work for about 2 hours and then will refuse any further connections until the machine has restarted. But again a short time later it will begin refusing connections. This is a recent development and there have been no changes to the configuration that would cause this behavior. This behavior developed recently, in the past it will work for about a month, then have to be restarted and it will continue to work just fine. It is within the last week that this constant start and shutdown has occured. Any ideas or information that I need to provide just let me know.
 
Update::

The issue for this was due to constant SYN Attacks. Each time a new attack was initiated it was disable my VPN services. So my next question is if anyone has any ideas on stopping in progress syn attacks?
