Understanding LAN Gateway Connections to External Networks #3416571 (License: Personal Use)

This diagram depicts a typical local area network (LAN) consisting of three desktop computers connected to a central gateway device-often a router or firewall-that serves as the bridge to the external network or internet. The gateway manages traffic flow, translates addresses (via NAT), and enforces security policies between internal and external networks. Such setups are foundational in home, office, and enterprise environments for enabling internet access while maintaining internal network integrity.

Used in educational articles, IT training materials, or networking guides to explain basic network architecture; matches user intent for understanding how LANs interconnect with the internet via gateways.
