MikroTik Bridge VLAN Filtering – Full Explanation with Configuration

Bridge VLAN Filtering in MikroTik is essential when you're managing VLANs (Virtual LANs) using hardware offloading for high performance (using a bridge instead of a router). It's the modern and efficient method for VLAN management in RouterOS 6.41+ and RouterOS v7.

🔐 What is Bridge VLAN Filtering?

Bridge VLAN filtering allows you to isolate or segment traffic on different VLANs through one bridge interface, applying VLAN rules per-port efficiently.

🧱 Key Concepts for VLAN Filtering:

  • Bridge: Logical switch combining multiple interfaces.

  • VLAN: Virtual separation of Layer 2 domains.

  • PVID (Port VLAN ID): Used for untagged incoming traffic.

  • Tagged: Traffic with VLAN ID.

  • Untagged: Plain Ethernet traffic.

✅ Example Scenario for the Mikrotik Configuration. 

If We have:

  • ether1 as uplink to trunk (to switch or another router)

  • ether2 for VLAN 10

  • ether3 for VLAN 20

🎯 Goal:

  • Create VLAN 10 and VLAN 20.

  • Pass VLAN traffic using bridge with filtering.

  • Make sure each port can only communicate within its VLAN.

⚙️ Step-by-Step Configuration (CLI)

🔹 Step 1: Create a Bridge


            /interface bridge
               add name=bridge1 vlan-filtering=yes

🔹 Step 2: Add Ports to the Bridge

             /interface bridge port
               add bridge=bridge1 interface=ether1
               add bridge=bridge1 interface=ether2 pvid=10
               add bridge=bridge1 interface=ether3 pvid=20

  • ether1: Trunk port (allows tagged VLANs)

  • ether2 and ether3: Access ports (untagged, assigned PVID)

🔹 Step 3: Add VLANs to the Bridge

            /interface bridge vlan
               add bridge=bridge1 vlan-ids=10 tagged=ether1 untagged=ether2
               add bridge=bridge1 vlan-ids=20 tagged=ether1 untagged=ether3

🔹 Step 4: Add VLAN Interfaces (optional for routing or IP assigning)

            /interface vlan
               add interface=bridge1 name=vlan10 vlan-id=10
               add interface=bridge1 name=vlan20 vlan-id=20

🔹 Step 5: Assign IP Addresses (if needed)

            /ip address
               add address=192.168.10.1/24 interface=vlan10
               add address=192.168.20.1/24 interface=vlan20

🧪 Verify of your configuration

  • See bridge VLAN configuration:

        /interface bridge vlan print

  • Check PVIDs and ports:


        /interface bridge port print

  • Monitor traffic:


        /interface bridge monitor bridge1

🛡️ Security Tips to configure this in Mikrotik. 

  • Always filter VLANs to block unnecessary traffic.

  • Set vlan-filtering=yes to activate rules.

  • Avoid placing management access on trunk ports without proper firewall rules.

  ARP Spoofing and MITM Attacks with Bettercap In the world of cybersecurity, one of the most common attack techniques used by hackers is the Man-in-the-Middle (MITM) attack, often combined with ARP (Address Resolution Protocol) spoofing. This article will explain the concepts of ARP spoofing, MITM attacks, why attackers use these methods, and how to use the Bettercap tool to perform these attacks effectively. I have made a youtube Video - Network hacking for this penetration attack. This is only for education purpose so please don't use this for any harmful activities. The author will not be liable for any bad activities.  What is ARP Spoofing? ARP spoofing, also known as ARP poisoning, is a method of attacking a local area network (LAN) by sending fake ARP messages to associate an attacker’s MAC address with the IP address of another device (such as a router or another user’s machine). This trick allows the attacker to intercept or alter traffic between devices on the...

  MikroTik Network Security: How to Prevent ARP Spoofing and DNS Attacks   Understanding ARP Spoofing and DNS Spoofing        ·         ARP Spoofing: Attackers send fake ARP messages on the network to associate their MAC address               with an IP address (e.g., your gateway). This allows them to intercept, modify, or block network traffic (man-in-the-middle attacks). ·          DNS Spoofing: Attackers alter DNS queries to redirect users to malicious websites by sending false DNS responses or poisoning the DNS cache.  Here we divide the topic for best understanding and point out those Attacks prevention techniques step by step I have made a description youtube video for this if you like can watch this too.
