Hello Team,

We have a dmvpn network and our office is experiencing timeouts during working hours.

When I begin troubleshooting I notice that the problem starts around 9:30 AM to 5:00 leads me to believe that a workstation in the company is causing the issue.

It only happens here at our office.

The tunnel from our office is generated with a Cisco 1941 router and is also connected to a Cisco ASA 5508-X

The FireWall does the ISP Fail-over for the router's tunnel. So if one ISP fails the tunnel switches the connection to the secondary ISP.

The problem with this timeouts is with the citrix sessions. We need to restart them all day long....

Any advice much appreciated.

Thank you!
