Hence, for the translation above, the Inside interface is considered the real interface. Moreover, the real IP exists on the ASA’s Inside interface. Hence, 172.16.30.15 is considered the real IP address. 15 is really configured with the IP address 172.16.30.15, which means the actual NIC really has the IP address 172.16.30.15 configured. The word real indicates what is really configured on a server.įor example, the web server at the IP address. We will define these with the example of a Static NAT below: These terms can be applied to IP addresses or interfaces. NAT configuration on the Cisco ASA will make use of the keywords real and mapped. If you had done the “pipe include” without the in-line option you just would have received the full name of the object, but not the object’s definition. Object network WEB-SERVER host 172.16.30.15
To configure a network object, first use the following syntax to create the object:Īsa98# show run object in-line | include WEB The idea is to configure and define an object, then reference that one item in your configuration by the object’s name.
a service object - represents one set of a Protocol, Source Port, and/or Destination port.a network object - represents one IP address, or one IP Subnet, or one IP address range.ObjectsĪn object is a construct which represents any single item in your network environment. In Part 1 of this article we will discuss all five of these terms. The configuration of objects involve the keywords real and mapped. The syntax for both makes use of a construct known as an object.
#FIREWALL CONFIGURATION ASA 5505 CISCO PACKET TRACER MANUAL#
These two methods are referred to as Auto NAT and Manual NAT. There are two sets of syntax available for configuring address translation on a Cisco ASA. Or any version of Cisco Firepower firewalls. This article is applicable to the Command Line Interface (CLI) configuration of Cisco ASA and Cisco ASA-X firewalls running code versions 8.4 and above.
