Router
The device that forwards packets between different networks
Core Idea
A router is the device or software layer that decides where packets should go next when they move between networks. It may look like a simple home box, or it may be something richer like OPNsense with policies and firewall controls built in.
Why It Matters Here
Mathbong uses routers as the shared idea behind home gateways, OPNsense, default routes, and internal network segmentation. The useful mindset is not just "the box that gives internet," but the control point that actually connects boundaries.
