Cisco ASA Audit Event: 305011

305011: Built TCP, UDP, or ICMP translation

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-6-305011: Built {dynamic|static} {TCP|UDP|ICMP} translation from interface_name: real_address / real_port [(idfw_user)] to interface_name: mapped_address / mapped_port.

Event 305011 is generated when a TCP, UDP, or ICMP address translation slot is created. The slot would translate the source address from the local side to the global side. In reverse, the slot would also translate the destination address from the global side to the local side.
