On Cisco ASA the answer is simple: use objects instead of actual IP addresses. Firewall and OSI Reference Model. A firewall system can work on five layers of the OSI-ISO reference model. But most of them run at only four layers i.e. data-link layer, network layer, transport layer, and application layers. The number of layers envelops by a firewall is dependent upon the type of firewall used.Firewall filters are the Junos version of an ACL. They are used to match traffic and apply an action. This can be for security (allow or deny traffic), but it can also be for a policy (such as a routing or CoS policy). Generally, firewall filters are stateless. The SRX and MX platforms can support statful firewall filters as well.The show firewall filter filter-name command limits the display information to the counters and policers that are defined for the specified filter.
