MikroTik Training documents / MikroTik Schulungsunterlagen

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.

I appreciate any feedback regarding the documents. Please feel free to contact me.

 

In den letzten Wochen habe ich einige firmeninterne MikroTik Router OS Schulungen für meine Kollegen abgehalten. Dabei entstanden meherer Dokumente, die die Schulungen dokumentieren und als Handbuch zum Nachbau der Konfigurationen dienen. Damit diese Dokumente nicht einsam und sinnlos auf meiner Festplatte verweilen, teile ich sie mit euch.

Für Rückmeldung zu den Dokumenten bin ich dankbar. Schreibt mir einfach.
