Dual-homed firewall—This is a firewall system that has two or more network interfaces, each of which is
connected to a different network. A dual-homed firewall usually acts to block or filter some or all of the traffic
trying to pass between the networks. A dual-homed firewall system is a more restrictive form of a screened-host
firewall system in which a dual-homed bastion host is configured with one interface established for information
servers and another for private network host computers.
