Overview
Check your software version and reimage if necessary, obtain your licenses, and make sure you can connect.
The mid-range Secure Firewall 3100 supports your evolving world. It makes hybrid work and zero trust practical, with the flexibility to ensure strong return on investment. The Secure Firewall 3100 is a threat-focused security appliance that delivers business resiliency and superior threat defense. It offers outstanding performance for multiple firewall use cases, even when advanced threat functions are enabled. These performance capabilities are enabled by a modern CPU architecture coupled with purpose-built hardware that optimizes firewall, cryptographic, and threat inspection functions. The Secure Firewall 3100 supports use cases from the Internet edge to the data center and private cloud. The Secure Firewall 3100 supports multi-instance and clustering to deliver increased performance that can scale to meet your needs as your organization grows.
Install the firewall at a branch office and manage it on the outside interface using a central Secure Firewall Management Center.
Outside management is not supported with clustering or multi-instance mode. See the getting started guide for a Firewall Management Center on a local management network. Zero-Touch Provisioning is not supported with clustering or multi-instance mode, even on the Management interface.
For high availability if you use zero-touch provisioning, we recommend using the Management interface. If you use zero-touch provisioning on outside and want to use high availability, you will have to change the outside IP address to a static address after registration.
