Configuration management, also known as change management, is a process by which configuration changes are proposed, reviewed, approved, and deployed. In the context of a Cisco firewall device configuration, two additional aspects of configuration management are critical: configuration archiving and security Cisco ASA 5505 firewall; Layer 2 switch (used only to connect the LAN hosts, without any additional configuration) Our task: allow the internal LAN hosts to access the Internet through the firewall. Step 0. Clear configuration (Should be done only on new or test lab equipment, since it completely erases all existing configuration Basic ASA Configuration. Before dealing with any specific configuration procedure for the Adaptive Security Appliance (ASA), you need to understand a set of basic concepts. Example 3-1 shows a summary of the boot process for an ASA 5505 appliance whose factory settings have not been changed yet
On Cisco Router/Switches: When you execute the show running-config (show run) command on Cisco router/Switches, the output will be paged through one screen at a time. This is useful as Cisco configuration can be very long and can have thousands of lines Throughout my professional career in networking I was lucky to work with all Cisco firewall models and therefore I have experienced the evolution of every firewall product developed by Cisco. For the SMB/SOHO market, Cisco's initial offering was the PIX 501, followed by the successful Cisco ASA 5505 7.Configuration backup. The configuration backup is backed up to 192.168.1.1 via tftp. The backup name is configuration20200101.cfg. We will have other articles about commands of Fortinet firewalls in the near future, so stay tuned. You can also enter your email address in the upper right corner of the page to subscribe to our blog Router (config)# firewall multiple-vlan-interfaces. Step 2 To add a VLAN interface to the MSFC, enter the following command: Router (config)# interface vlan vlan_number. Step 3 To set the IP address for this interface on the MSFC, enter the following command: Router (config-if)# ip address address mask
To configure Cisco IOS Zone Based Firewall, initial step is to create Zones and Zone Pairs.Consider the network topology below. How to create Zones. To create three Zones, INSIDE, OUTSIDE and DMZ, follow these configuration steps.. OmniSecuR1# configure terminal OmniSecuR1(config)# zone security INSIDE OmniSecuR1(config-sec-zone)# exit OmniSecuR1(config)# zone security OUTSIDE OmniSecuR1. Zone Based Firewall is the most advanced method of a stateful firewall that is available on Cisco IOS routers. The idea behind ZBF is that we don't assign access-lists to interfaces but we will create different zones.Interfaces will be assigned to the different zones and security policies will be assigned to traffic between zones.To show you why ZBF is useful, let me show you a picture
Note: The router commands and output in this lab are from a Cisco 1941 with Cisco IOS Release 15.4(3)M2 image with a Security Technology license. Other routers and Cisco IOS versions can be used.
