Doubt on Connection establishment through ASA.
Suppose an inside user A establishes connection through ASA to any outside server (Let say Server on port 80. ASA build xlate table, connection table and state table for this connection and maintain it for a period of time. My concern is , will ASA allow if Server B wants to connect user A taking all fields same(Source & Destination IP ,Source & Destination port, TCP seq and Ack no) during or after the communication ? Since Connection entry already exist in ASA while user A had initiated the connection for server B, ASA should allow the newly generated connection.
