How to Connect Between A and C?

Network

There are two switches as 192.168.1.0 and 192.168.2.0.
192.168.1.0 and 192.168.2.0 are different network environments.
That means A and C are also different networks.
At this moment, we need a router to connect between the different networks.

Gateway

There’s no way to connect between A and C directly.
So we need a door to connect between them.
In this case, we have a router.
We call it Gateway.

Default Gateway

Now, we know what is the gateway.
You can set a gateway as system default.
Default Gateway means the system use a gateway as default.
