VPN firewall modules application scenarios
VPN firewall modules work with the main network devices (such as 5800/7500/9500/12500 switches
and 6600/8800 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.
