Firewall module application
Firewall modules work with the main network devices (such as A5800/A7500/A9500/A12500
switches and A6600/A8800 routers). Deployed at the egress of a network, the firewall modules can
protect against external attacks and implement security access control of the internal network by using
security zones. You can meet the development of the network simply by installing more firewall modules
to a switch or router. Deploying two switches/routers with the firewall modules in the network can
improve service availability.
