• Screened host architectures use both packet filtering and a separate dedicated firewall, it allows packets to be screened before entering a network and accessing an internal proxy. While a screened subnet firewall architecture utilizes a DMZ as a dedicated port between the device and a single host. This helps even more with routing unauthorized network traffic, as all requests that occur within the network do not respond to outside IP addresses. Screened subnet firewalls with a DMZ offer way more security as it is very difficult to communicate with servers in a DMZ because they are only configured to communicate on the local network.
