Watchguard X550e SSL VPN drops - TCP RST packet without an associated connection

Posted on 2009-02-23
Last Modified: 2012-05-06
I have recently given access via SSL VPN to many of our emerency responders and every few days all SSL VPNs stop working. They act like they are connecting and then drop. They are connecting to an X550e (10.2.7) with the latest client. If I disable SSL and remove then re-add the users the issue goes away for a while but always returns. As a troubleshooting step, I have unchecked the "enable TCP SYN Checking" to no avail.

Any help would be much appreciated

    Can you post few sanitized logs from the traffic monitor when the issue happens; also does it happen to all users or specific users; also is there any frequency with which the issue happens.
    Do you also observe any disruption in other services when this issue is reported.

    Please provide more details.

    Thank you.
