The last few weeks I gave a lot of company-internal trainings about MikroTik RouterOS. Especially I trained my colleagues how to configure VPN connections and how to configure dynamic routing with OSPF. As result there are some training documents, which in my opinion are to valuable to let them rot on my hard disk. So, I share them with you. Note: The documents are in German.

Damit diese Dokumente nicht einsam und sinnlos auf meiner Festplatte verweilen, teile ich sie mit euch.
I just configured some IPSec tunnels to connect the management network to our company's local network and stumbled over a well known problem: I can ping hosts "behind" the router doing IPSec, but I cannot ping the router itself. Read why and how to circumvent this issue.
To see to what extent the jumpnet is used and to determine the utilization of Jens' internet connection (he's the hub in our hub-and-spoke network topology) we need a simple traffic graphing tool. This is where MRTG comes into play. This article describes how to configure MRTG and MikroTik to graph the traffic.

In the past years, I learned a lot about the technologies used in the internet and apart from some people dealing with them every day, nobody knows. One of these technologies is MPLS. I read a lot about it but never tried to set it up myself. Here we go...
