Firewall Policy Concept
A firewall device is commonly used to provide secure traffic control over an Ethernet network, as illustrated in
the following figure. Firewall devices are deployed at critical points between an external network (the
non-secure part) and an internal network (the secure part).
Firewall Policy Overview
The EtherDevice Router provides a Firewall Policy Overview that lists firewall policies by interface direction.
Select the From interface and To interface and then click the Show button. The Policy list table will show the
