Here are the steps you need to follow to block file extensions using a web proxy server on your mikroTik router:

Dst. Host: 0.0.0.0/0
Redirect to: (Leave this field blank)
Protocol: TCP
Dst. Port: 80

Once you have entered all the required information, click on the "OK" button to save the access rule.

Step 2: Create an IP Firewall Filter Rule

The next step is to create an IP firewall filter rule. To do this, you need to open the Winbox software and go to IP > Firewall. In the firewall window, click on the "Filter Rules" tab, and then click on the "+Add" button to create a new filter rule.

Once you have clicked on the "+Add" button, a new window will open. In this window, you need to enter the following information:

Chain: Forward
Src. Address: (Leave this field blank)
Dst. Address: (Leave this field blank)
Protocol: TCP
Dst. Port: 80
Action: Jump
Jump to: Web Proxy Access
Connection state: New

Once you have entered all the required information, click on the "OK" button to save the filter rule.

Step 3: Create Web Proxy Filter Rule

The final step is to create a web proxy filter rule. To do this, you need to open the Winbox software and go to IP > Web Proxy. In the web proxy window, click on the "Filter" tab, and then click on the "+Add" button to create a new filter rule.

Once you have clicked on the "+Add" button, a new window will open. In this window, you need to enter the following information:

Action: Deny
Src. Address: (Leave this field blank)
Dst. Host: (Leave this field blank)
File Extension(s): Enter the file extension you want to block. For example, if you want to block .zip files, enter "*.zip".
