Dear Experts,
We are expreincing problem with connection establishment through ASA between 02 hosts..
getting below entry on connection table , However there is no hits on respective access list.
TCP Outside 10.10.1.100:53370 inside 1172.16.1.100:3389, idle 0:00:11, byte 0, flags aXB
TCP Outside 10.10.1.100:53370 inside 1172.16.1.100:3389, idle 0:00:11, byte 0, flags aXB
TCP Outside 10.10.1.100:53370 inside 1172.16.1.100:3389, idle 0:00:11, byte 0, flags aXB
What i understand through this aXB Flag is
1- Ack from Outside is not there (a)
2- Inspected by Service Module (X)
3- SYN received from Outside (B).
Problem is - X - why being inspected by Service Module and what is the solution.
Show Module Output.
