302303: Built TCP state-bypass connection
Cisco ASA is a security device that provides the combined capabilities of a firewall, an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections. It helps to detect threats and stop attacks before they spread through the network.
Message: %ASA-6-302303: Built TCP state-bypass connection conn_id from initiator_interface: real_ip /real_port (mapped_ip /mapped_port) to responder_interface: real_ip /real_port (mapped_ip /mapped_port).
Event 302303 is generated when a new TCP-state-bypass connection that would bypass all the TCP state checks, additional security checks and inspections, is created.
How could you resolve this situation?
Use the 'no set connection advanced-options tcp-state-bypass' command to secure TCP traffic with all the normal TCP state checks as well as all other security checks and inspections.
