Penjelasan lengkap dan penyelesaian UKK TKJ 2025 paket 2

Summary

This video script outlines a practical exercise for a technical course on computer and network engineering, focusing on network security, installation, and dynamic/static routing. The instructor demonstrates the configuration of MikroTik routers for LAN and WLAN setups, including network addressing, firewall settings, and proxy server installation. Key topics include setting up local IP addresses, DNS, securing websites with web proxies, creating DHCP servers, and configuring dynamic routing protocols like OSPF. The step-by-step guide is aimed at helping students build functional network environments, with emphasis on both theoretical and hands-on practical skills for the 2024-2025 academic year.

Takeaways

• 😀 The task is about designing and implementing network security for a computer and networking technology major.
• 😀 The project includes configuring two Mikrotik routers (RB750 and RB951 UI 2HND) for internet and local area network (LAN) connectivity.
• 😀 The first router (RB750) acts as the production server, while the second router (RB951 UI 2HND) functions as an access point for wireless clients.
• 😀 Configuration begins by setting up IP addresses for both routers using Winbox and connecting them to a switch for internet access.
• 😀 The LAN on router A is configured with IP address 192.18.1.111/34, and router B uses 192.210.10.1/24 for its LAN interface.
• 😀 DNS servers (8.8.8.8 and 8.8.4.4) are configured on both routers to enable internet access.
• 😀 A firewall NAT rule is created to enable proper routing for internet connectivity.
• 😀 Proxy server installation and configuration on Mikrotik router is done using the web proxy feature with port 3128 for caching.
• 😀 Transparent proxy setup is implemented to block specific websites such as www.linux.org and www.linux.co.id.
• 😀 Router B is configured with DHCP to assign IP addresses automatically to clients connecting via wireless LAN (WLAN), and the wireless security profile is set up with a password.
• 😀 Dynamic routing (OSPF) is configured on both routers to ensure communication between the local LAN and wireless networks, enabling connectivity across different network segments.

Q & A

What is the main focus of the task described in the script?

The task focuses on designing and building a network security system, including the installation and configuration of dynamic routing, as well as setting up proxies and firewalls in a local area network using MikroTik routers.

What are the models of the MikroTik routers mentioned in the task?

The MikroTik router models mentioned are RB 750 for Router A and RB 951 UI 2HND for Router B.

What is the purpose of Router A in the described network setup?

Router A functions as a production server connected to the internet and provides network access to a computer through a local area network (LAN).

How are the routers connected in the network setup?

Router A is connected to a switch that provides internet access, while Router B is configured as an access point for wireless network connections, allowing clients to access the internet through wireless devices like smartphones and laptops.

What software is used to configure the MikroTik routers?

The software used to configure the MikroTik routers is Winbox, which is downloaded from the MikroTik website and used for remote configuration.

What IP addresses are configured for the interfaces on Router A?

For Router A, the IP addresses configured are 192.18.1.111/34 for interface 1 (connected to the internet), and 192.210.10.1/24 for interface 2 (connected to the local computer).

How is network security implemented in the described setup?

Network security is implemented by setting up a proxy server on Router A, blocking certain websites, and configuring a transparent proxy to prevent access to specific sites such as 'www.linux.org'.

What is the role of Router B in the network setup?

Router B acts as a wireless access point, allowing clients to connect via Wi-Fi. It also performs dynamic routing and DHCP functionality to manage the local network.

How is dynamic routing configured between Router A and Router B?

Dynamic routing is configured using OSPF (Open Shortest Path First) protocol on both routers, with IP addresses and networks added for each router's interfaces to enable communication between the two routers.

What additional configuration is done on Router B to support wireless connectivity?

On Router B, a security profile is created with a password for the wireless network, and the wireless mode is set to 'AP Bridge' to allow devices to connect to the wireless network. The SSID is set to 'UKK it' for identification.
