Hello Ibrahim,

Run captures on the ASA Inside interface

capture capin interface inside trace  match tcp/udp host x.x.x.x(Remote_client_local_pool_ip) host y.y.y.y ( internal host_ip) eq (tcp or udp port)

then create an ASP capture ( will show all the packets being dropped by the Accelerated Security Path {Algorithm used by the ASA}) With this we will be able to determine if the ASA is dropping the packets.

capture asp type asp-drop all circular-buffer

Then install wireskark on the server an run a capture while the VPN user connects, create a filter for the remotevpn ip address and check what happens ( witch messages you see ) when the user experiments the issue.

You can provide the

-Show cap capin

-Show cap asp | include x.x.x.x (Remote_client_local_pool_ip)

-The wireshark capture

     ''All of this after a connection was made and the issue was seeing)
