I installed a new Access Gateway appliance server 4.4 with latest HF1-6 and set tunnel for GroupWise client access to GroupWise POA. The tunnel port is 1677 ..... set from GW client to GW POA.

When I try to access a GW POA with a GW client, through NAM tunnel, the GW client only connects occasionally. And when the tunnel is established it breaks after a while.

Any idea how can I found cause for that issue or resolve it?

Thanks in advance.
