L7P Blocking	- Highly specific＜br＞- Can block HTTPS	- Resource-intensive＜br＞- Requires regular updates
DNS Blocking	- Easy to implement＜br＞- Low resource usage	- Easily bypassed＜br＞- Doesn't work for IP-based access
IP Blocking	- Effective for known IPs＜br＞- Low overhead	- Can lead to overblocking＜br＞- Requires constant IP list updates

Example Configuration

To block a specific website using L7P:

1. Create the L7 protocol:

   /ip firewall layer7-protocol
   add name=block-example regexp="^.*(example\.com).*$"
   

2. Create a firewall filter rule:

   /ip firewall filter
   add chain=forward protocol=tcp layer7-protocol=block-example action=drop

3. Connection state

Here's a basic mangle rule structure for HTTPS blocking:

Rule Component	Description
Chain	forward
Protocol	tcp
Dst. Port	443
Action	mark packet

Implementing HTTPS Blocking

To block HTTPS traffic to specific websites:

1. Identify the IP addresses of target websites
2. Create mangle rules to mark packets
3. Set up firewall rules to drop marked packets

Here's a step-by-step process:

1. Add IP addresses to an address list
2. Create mangle rules to mark packets
3. Add firewall filter rules to drop marked packets

This method ensures that HTTPS traffic to specified sites is blocked while allowing other HTTPS connections to pass through, maintaining a balance between security and usability.

Allow a Certain User to Visit a Blocked Website [Unblock Website]

Unblocking a Specific User

In certain scenarios, you may need to grant access to a blocked website for a specific user while maintaining restrictions for others. MikroTik offers flexible options to achieve this. Here's how you can allow a certain user to visit a blocked website:
