October 2017, ISP load balancing with Mikrotik Nth
In this webinar, we discussed an advanced topic of mikrotik firewall features: nth packet matcher. we assumed the readers already have a solid understanding of prerequisite knowledge. we started the discussion with the basic concepts of traffic load balancing, and then move to the nth discussion.

October 2017, GLC Webinar: Mikrotik Firewall Mangle
Mikrotik Firewall Mangle. In this webinar, we started the discussion with the basic concepts of firewall in mikrotik. We then focusing on firewall mangle as it is said in title. we discussed three most-used mangle action on mikrotik routerOS, they are: mark-packet, mark-connection, mark-routing. each mangle action has its own example case of its usage.

September 2017, GLC webinar: Integrating Radius with Mikrotik
Integrating Radius with Mikrotik. In this webinar, we started the discussion from the introduction of radius, AAA concept, and typical RADIUS implementation. We then move forward on example configuration on NAS (to connect to radius), radius server (to allow NAS query the RADIUS server), creating services on radius server, and last create account on radius server. At the end of presentation, we discuss about the benefits of using GLC radius compared to traditional radius server. (more…)
combining 2 ISP with one mikrotik routerboard
In this project (click here for the detail), our client requests to combining 2 ISP with one mikrotik. This case is different from the previous one that was using BGP protocol and whole end devices are using public IP address. This project is challenging because both ISP gives Public IP address which is just enough for point-to-point connection only. End-devices (laptop, PC, etc) will use private IP address, where router will do NAT (Network Address Translation) on these private IP when they are going out to internet. Topology of the network can be seen at the picture above. So, the technical plan would be: (more…)
September 2017, GLC webinar: Wireless CSMA with Mikrotik
Wireless CSMA with Mikrotik. In this webinar, we started the discussion about essential concept of multiplexed communication which is applied on wired and wireless communication. we then carried on with CSMA/CD, how wireless communication works, CSMA/CA, and wireless configuration on mikrotik. (more…)
Why it is a bad idea to drop packets using l7-filter on mikrotik
[caption id="attachment_1079" align="alignleft" width="300"] picture from wikipedia[/caption] This article will explain the effect on RouterOS if you drop packets using l7-filter on mikrotik. As we know from previous articles here, mikrotik supports Regex for pattern matching. one of its purpose to match traffic based on information on layer 7 (application layer). Mikrotik has wiki page that explain how the L7 filter works. and on that page, they already warns user that using l7-filter for dropping packet will increase CPU usage and cause router instability.

August 2017, GLC Webinar: SSL Certificate with Mikrotik
SSL Certificate with Mikrotik. In this webinar, we will discuss about the basic concept of security, confidentiality, encryption, symmetric and assymetric encryption, SSL certificate, and HTTPS. after that we discuss certificate feature on Mikrotik RouterOS, creating self-signed certificate, and import CA signed certificate to RouterOS. (more…)
August 2017, GLC Webinar: BGP filter on mikrotik
BGP filter on mikrotik. In this webinar, we start the discussion with an introduction to BGP like AS to AS connection, comparison BGP routing and traditional routing, also BGP peering. we then talk about problem that might occur during BGP peering, its effects, and the solution. finally we cover an example of how to configure BGP filter on mikrotik. (more…)
July 2017, GLC Webinar: VRRP on Mikrotik
vrrp on mikrotik. In this webinar, we discuss a mikrotik feature that is called VRRP (Virtual Router Redundancy Protocol ) which could provide dedundancy on the your network. We started the webinar by introducing the VRRP protocol, then discuss an example implementation on Mikrotik Router. some mistakes on VRRP configuration were also covered here. (more…)
