Cisco ASA DMZ Configuration Example Design Principle. The network diagram below describes common network requirements in a corporate environment. A Cisco ASA is deployed as an Internet gateway, providing outbound Internet access to all internal hosts. There are four security levels configured on the ASA, LAN, DMZ1, DMZ2 and outside.
Zone Based Firewall Configuration Example 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: Configuration and WebGUI — Basic Firewall Configuration DMZ Configuration¶ For DNS from the firewall: Allow TCP/UDP from DMZ subnet to DMZ Address port 53. For accessing the GUI (optional): Allow TCP from DMZ subnet to DMZ address port 443. To ping the firewall from the DMZ: Allow ICMP from DMZ subnet to DMZ address. If there is any traffic required from DMZ to LAN: Allow any traffic required from How to Create a Basic DMZ (Demilitarized Zone) Network in May 26, 2020 Lock IT Down: Implementing a DMZ - TechRepublic

A Cisco ASA is deployed as an Internet gateway, providing outbound Internet access to all internal hosts. There are four security levels configured on the ASA, LAN, DMZ1, DMZ2 and outside. 5.3 Example DMZ Configuration This section reviews the basic considerations to keep in mind when designing your DMZ and configuring it in App Net Manager. For example, if you have two web servers and a mail server on your corporate network. The DMZ configuration is identical to the VLAN configuration. There are no restrictions on the IP address or subnet assigned to the DMZ port, except it cannot be identical to the IP address given to the predefined VLANs. Note Up to 4 DMZs can be configured on the security appliance. Figure 4-1 Example DMZ with One Public IP Address for WAN and DMZ
