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.

combining 2 ISP with one mikrotik routerboard

load balancing, PCC
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…)

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.
