 ## What is a "port"?
----

 Ports are different channels through which your router sends and receives data. This allows multiple services to run simultaneously.  
 When it receives data through a port, your router forwards that data to the machine that:

 So, your router acts as a data dispatcher between the internet and your local machines.
 
 ## Port Forwarding
----
+
 Forwarding a `port` means setting a rule that specifies which `source` can send data to which `port` on your router, which will then forward it to a specific `port` on a specific `machine`. The `sources` and `destination machine` are identified by their IP addresses.

 ## DHCP
----
+
 Every time a device connects to your local network, your router assigns it an IP address using DHCP rules.  
 This IP is randomly selected from a predefined pool.  
 At every device reboot, the IP may change — which is problematic if you're forwarding ports, as the target IP may no longer be valid.
