Efficient Content Filtering With MikroTik Router Proxy Server

Have you ever heard of a transparent proxy server? It’s a server that intercepts all traffic between clients and the internet without requiring any configuration on the client side. Today, we’re going to talk about how to configure a MikroTik Router Web Proxy.

But first, what is a proxy server? A proxy server is a server that acts as an intermediary between a client and the internet. It’s essentially a gateway between the client and the internet that receives requests from the client and forwards them to the internet. Proxy servers are used for a variety of reasons, including:

To improve performance by caching frequently accessed resources
To filter out unwanted content, such as ads or malicious content
To hide the client’s IP address from the internet
To monitor and control internet usage, such as limiting access to certain websites or applications

Now, let’s dive into how to configure a MikroTik Router Web Proxy. Keep in mind that this guide assumes you have a basic understanding of MikroTik RouterOS and networking concepts.

Step 1: Configure IP Addresses

The first step in configuring a MikroTik Router Web Proxy is to configure the IP addresses for the router’s interfaces. In this example, we’re going to assume that the router has two interfaces: one connected to the internet and one connected to the internal network.

To configure IP addresses, navigate to IP > Addresses and add IP addresses to both interfaces. For example, if the interface connected to the internet has the IP address of 203.0.113.1/24 and the interface connected to the internal network has the IP address of 192.168.1.1/24, add those IP addresses here.

Step 2: Enable Web Proxy

The next step is to enable the web proxy on the MikroTik Router. To do this, navigate to IP > Web Proxy and click “Enable.” This will enable the web proxy and configure it with default settings.

While the default settings may be sufficient for small networks, it’s a good idea to configure the web proxy to meet your specific needs. Let’s take a look at some of the key configuration options.

Step 3: Configure Web Proxy Settings

There are several key settings you’ll want to configure on the MikroTik Router Web Proxy:

Cache Size

The cache size determines how much disk space the web proxy will use to cache web content. The default cache size is 256 MB. However, if you have a larger network or if you want to cache more content, you may want to increase the cache size.

To change the cache size, navigate to IP > Web Proxy and click “Settings.” From here, you can change the cache size under the “Cache Settings” section.

Cache on Disk

The cache on disk option determines whether the web proxy will store its cache on disk or in RAM. If you have a lot of RAM available, caching in RAM may be faster. However, if you have limited RAM or if you want to cache a large amount of data, caching on disk may be preferable.

To enable caching on disk, navigate to IP > Web Proxy and click “Settings.” From here, you can enable caching on disk under the “Cache Settings” section.

Transparent Proxy Settings

The transparent proxy settings determine whether the web proxy will be transparent or not. If the web proxy is transparent, clients won’t need to configure any settings to use it. However, if the web proxy is not transparent, clients will need to configure their browsers or applications to use it.

To enable transparent proxy settings, navigate to IP > Web Proxy and click “Settings.” From here, you can enable transparent proxy under the “General” section.

Access Restrictions

The access restrictions options allow you to control which clients are allowed to use the web proxy and which sites clients can access through the web proxy. For example, you may want to restrict access to social media sites or streaming video sites.

To configure access restrictions, navigate to IP > Web Proxy and click “Access.” From here, you can configure access rules for the web proxy.

Step 4: Test Web Proxy

Now that you’ve configured the MikroTik Router Web Proxy, it’s time to test it. To test the web proxy, simply configure a client to use the web proxy and try to access a website. If the website loads normally and the web proxy appears to be working, congratulations! You’ve successfully configured a MikroTik Router Web Proxy.

Conclusion

Configuring a MikroTik Router Web Proxy is a relatively straightforward process, but it does require some knowledge of networking concepts and MikroTik RouterOS. By following the steps outlined in this guide, you should be able to configure a web proxy that meets your specific needs.

Whether you’re looking to improve performance, filter out unwanted content, or monitor and control internet usage, a web proxy can be a powerful tool for managing your network. So why not give it a try and see how it can benefit your organization?
