<p style="margin-top:0; margin-bottom:0">I have an issue with a tunnel where the tunnel is up, but after some time incoming traffic stops flowing. All traffic is initiated from the remote end. In order to get traffic flowing again I have to initiate some
traffic to the other side. Any ideas why this might be happening and how to correct?</p>
