Study Notes

Wireless Router Configuration and Security Measures

DMZ (Demilitarized Zone) can be set up on a wireless router to forward all traffic from the internet to a specific IP address or MAC address.
This allows devices such as servers, game machines, or web cameras to be accessed by anyone, but they are exposed to potential attacks and should have firewall software installed.
Port forwarding is a rule-based method of directing traffic between devices on separate networks, allowing specific programs and applications to communicate with devices on different networks.
Port triggering enables the temporary forwarding of data through inbound ports to a specific device, based on designated port ranges used to make outbound requests.
MAC address filtering specifies which device MAC addresses are allowed to or blocked from sending data on a network, and many wireless routers only provide the option of allowing or blocking MAC addresses, not both.
The MAC address for a Windows computer can be found using the ipconfig /all command, while it may be labeled differently on other devices such as iPhones and Androids.
Devices like PlayStation 4 and Windows PCs may have multiple MAC addresses for different network connections, and manually configuring multiple MAC addresses can be overwhelming.
New devices may be added to the network at any time, making manual entry and maintenance of MAC addresses challenging.
Hardware firewalls can be used to block TCP and UDP ports to prevent unauthorized access in and out of a LAN, but specific ports may need to be opened for certain programs and applications to communicate with devices on different networks.
Port numbers are associated with specific services, such as FTP, HTTP, HTTPS, and POP3, and the rules determine which traffic is sent to the LAN.
Port forwarding is enabled for specific port numbers, such as port 80 associated with HTTP, and is associated with specific devices on the network, such as a web server with the IPv4 address 10.10.10.50.
Port triggering allows data forwarding based on designated port ranges used to make outbound requests, for example, for gaming and chat applications.
