Linux Gateway
This is the default gateway and it provisions the appropriate firewalls and NAT rules on the VM.
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco UCS Director provides the ability to create an application container that makes use of a physical Adaptive Security Appliance (ASA) gateway.
This physical gateway allows one-way (inside to outside) connections without an explicit configuration for each internal system and application.
Cisco UCS Director provides the ability to create an application container that makes use of an Adaptive Security Virtual Appliance (ASAv) gateway. The Cisco ASAv supports both traditional tiered data center deployments and the fabric-based deployments of Cisco Application Centric Infrastructure (ACI) environments. The ASAv provides consistent, transparent security across physical, virtual, application-centric, SDN, and cloud environments.
The ASAv brings firewall capabilities to virtualized environments to secure data center traffic within multi-tenant architectures. As it is optimized for data center environments, the ASAv supports vSwitches. The ASAv can therefore be deployed in Cisco, hybrid, and even non-Cisco data centers, significantly reducing administrative overhead and improving flexibility and operational efficiency.
For ACI deployments, the Cisco Application Policy Infrastructure Controller (APIC) provides a single point of control for both network and security management. APIC can provision ASAv security as a service, manage policy, and monitor the entire environment for a unified view of the entire distributed infrastructure. Many APIC functions can be controlled through Cisco UCS Director, including creation and deletion of ASAv gateways.
