Exploring Proxy Server Features In MikroTik RouterOS

Have you ever heard of Mikrotik? It is a type of network equipment that carries out a variety of tasks such as routing, firewall, bandwidth management, wireless access point, hotspot gateway, VPN server, and many others. One of the most interesting features of Mikrotik is creating a transparent proxy, which can filter traffic without client-side configuration. In this guide, we will walk you through the process of creating a transparent proxy Mikrotik.

Details

The first step to creating a transparent proxy on Mikrotik is to create a NAT rule that redirects HTTP traffic to the proxy. This is done by going to IP > Firewall > NAT and creating a new rule with the following settings:

• Action: redirect
• Chain: dstnat
• Dst. Port: 80
• Protocol: tcp
• Redirect Target IP: IP Address of your Mikrotik Router
• Redirect Target Port: 8080

Once you have set up the NAT rule, you need to configure the proxy settings. This is done by going to IP > Web Proxy and configuring the following settings:

• Action: enable
• Address: IP Address of your Mikrotik Router
• Port: 8080
• Transparent Proxy: yes

Now that you have set up the NAT rule and the proxy settings, you need to create a firewall rule to allow HTTP traffic to the proxy. This is done by going to IP > Firewall > Filter and creating a new rule with the following settings:

• Action: accept
• Chain: input
• Dst. Port: 8080
• Protocol: tcp

That’s it! You have successfully created a transparent proxy on Mikrotik.

Tips

Here are some tips to help you get the most out of your transparent proxy:

• Use caching to improve the performance of your proxy. Mikrotik has built-in caching that can significantly reduce the load on your network.
• Use blacklist and whitelist to block or allow specific websites or categories of websites.
• Combine your transparent proxy with other Mikrotik features like hotspot gateway or VPN server to create a comprehensive network solution.
