4.7.3. Transparent Mode Scenarios Chapter 4. Routing • Source Interface: lan • Destination Interface: any • Source Network: 10.0.0.0/24 • Destination Network: all-nets (0.0.0.0/0) 3. Click OK Scenario 2 Here the NetDefend Firewall in Transparent Mode separates server resources from an internal network by connecting them to a separate interface without the need for different address ranges. All hosts connected to LAN and DMZ (the lan and dmz interfaces) share the 10.0.0.0/24 address space. As this is configured using Transparent Mode any IP address can be used for the servers, and there is no need for the hosts on the internal network to know if a resource is on the same network or placed on the DMZ. The hosts on the internal network are allowed to communicate with an HTTP server on DMZ while the HTTP server on the DMZ can be reached from the Internet. The NetDefend Firewall is transparent between the DMZ and LAN but traffic is still controlled by the IP rule set. Figure 4.21. Transparent Mode Scenario 2 Example 4.18. Setting up Transparent Mode for Scenario 2 Configure a Switch Route over the LAN and DMZ interfaces for address range 10.0.0.0/24 (assume the WAN interface is already configured).
