Mikrotik Mirror Bridge, This set of features makes bridge operation more like a traditional Ethernet switch and allows to overcome Spanning Tree compatibility issues compared to the configuration when tunnel-like VLAN interfaces are bridged. Controller Bridge (CB) and Port Extender (PE) is an IEEE 802. 10) A (lan, 10. Hello and welcome! In this video we will be looking at how to implement a wireless bridge between MikroTik devices. This MikroTik tutorial guides you through the seamless process of connecting disparate network segments. The SwOS version is 2. Admittedly, it is always best to run a cable and connect multiple devices to a switch. This is useful for simplifying network design, enabling communication between devices on different interfaces, and implementing VLANs. I have a linux server connected to an ethernet port of my Mikrotik hAP ac², and an AP to another one. it's works becuase the 4011 see but ip's on both vlans as a connected route attached to an interface. 1 with routerboard firmware 3. For almost as long as I have been using wireless networks, I have had a nagging problem. Understand how Bridge Horizon works with this tutorial. If I go to"switch" > Select switch1, I can select mirror-source and mirror-target , but I only can take just one mirror source. In essence a bridge allows you to bundle different interfaces tog RouterOS bridge can process IGMP v1/v2/v3 and MLD v1/v2 packets. The switch can also run a DHCP client, see if a different IP address has been assigned by the DHCP server. Aug 29, 2025 · If you set mirror-source as an Ethernet port for a device with at least two switch chips and these mirror-source ports are in a single bridge while mirror-target for both switch chips are set to send the packets to the CPU, then this will result in a loop, which can make your device inaccessible. Understand how to create, configure, and use bridges to connect and segment your network effectively. We will configure MikroTik router to stream captured packets to our computer where we will be capturing and analyzing them with Wireshark. It’s not obvious why this would be so. 151) R (routerboard 951g 2HnD) normally A and B are connected to G like this: A ↔ G ↔ B , but we insert R I tried today to set up a mirror for VLAN 50 traffic on an uplink to a firewall, mirroring to an IDS system on another port. SwOS default IP address: 192. My goal is to mirror traffic from ether5 to ether6. Basically, every port in a bridge is assigned a horizon value, and RouterOS will only forward frames to other interfaces in the bridge that have different horizon values. VLAN Since RouterOS version 6. Multiple hardware offloaded bridge configuration is designed as a fast and simple port isolation solution, but it limits part of the VLAN functionality supported by the CRS switch-chip. Hello MikroTik community, I’m trying to set up port mirroring on my RB5009 and would like to verify if my current configuration is correct. So, you can isolate your network into multiple logical networks on a physical interface. 5 gbit/s Intel i226-v network cards for Securityonion. Can you elaborate? If mac address learning was disabled somehow then yes - it would be a hub, not a bridge. so a bridge is not required, since you'll probably just land the gateway and dhcp services on those vlans from the 4011, and connect it over to a switch. Support the Channel:⭐Become a Patreon: htt Learn the step-by-step process of setting up a bridge in MikroTik RouterOS. Expand your network without the cables using MikroTik's Wireless Bridging. On other hand, MikroTik Bridge integrates multiple… Expand your network without the cables using MikroTik's Wireless Bridging. ether24) for monitoring. This topic is a reaction to the countless cases of confusion regarding why the bridge “itself” must be listed among tagged or untagged ports of a VLAN in some cases, why the VLAN interfaces must be attached to the “bridge” rather than to its member ports etc. The implemented bridge IGMP/MLD snooping is based on RFC4541, and IGMP/MLD protocols are specified on RFC1112 (IGMPv1) RFC2236 (IGMPv2), RFC3376 (IGMPv3), RFC2710 (MLDv1), RFC3810 (MLDv2). Switching lets can switch packets in many different ways but mikrotik switch chips arent fast enough to do custom filters at wirespeed. Goal: use the router/managed switch to mirror the port the user client is on to the sniffer client and block any outgoing traffic the sniffer client may send. I am trying to setup Securityonion to make a SOC in my home network. Configuring an IP Address for the Bridge to ensure network connectivity. you can keep it this way. I was wondering if I can mirror traffic from AP to my linux server for real time traffic analyzing via ntopng or Wireshark. An example of MikroTik is renowned for its flexible use and competitive price.
