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. Is it safe for external traffic (DMZ) and internal traffic If the switch is a layer3 switch, DONT assign an ip address to the DMZ vlan, and avoid the inside vlan having an IP Address if you can. Make sure these meet at a firewall. I still prefer to physically seperate, but do use vlans for the set of DMZ zones I have (I have 3 at the moment). Cisco ASA 5505 DMZ with Private VLAN Configuration DMZ Zone: Interfaces E0/2, E0/3 in VLAN 30; Notice that in DMZ we have 2 publicly accessible servers (Web and Email Server) that they both belong in the same Layer2 vlan (VLAN30) and the same Layer3 network subnet (10.0.0.0/24). If we don’t configure “Private Vlans”, then if the Web or Email server gets hacked, the attacker can access the
Our Mission. We provide leading-edge network security at a fair price - regardless of organizational size or network sophistication. We believe that an open-source security model offers disruptive pricing along with the agility required to quickly address emerging threats.

Virtual LAN - Wikipedia A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this context virtual refers to a physical object recreated and altered by additional logic. VLANs work by applying tags to network frames and handling these tags in networking systems – creating the dmz/vlan within personal network - Spiceworks Mar 16, 2020 What Is a Virtual LAN (VLAN) and What Can It Do?
