What is the role of a multihomed host in a network penetration test?

• A. It serves as a firewall
• B. It can be used as a pivot to access internal network
• C. It isolates the tester and prevents pivoting
• D. It eliminates the need for lateral movement

Answer: (B)

A multihomed host provides a bridge between two or more networks by having distinct network interfaces on each. In a network penetration test, this lets you place a compromised machine at the edge of the external network and use it as a stepping stone to reach the internal network. Because the host sits on both sides, you can route traffic through it, perform port forwarding or tunneling, and access internal hosts and services that aren’t directly reachable from your tester machine. This pivoting capability enables deeper discovery and exploitation while using a single, controlled jump point. It’s not a firewall, and it doesn’t inherently isolate you or remove the need for lateral movement—pivoting through a multihomed host is a classic way to extend access into protected segments.
