Class Video – Mikrotik Basics
This is a 45 minute video that will walk you through configuring a Mikrotik for a standard network: ip addressing, routing, dhcp server/client, DNS, basic wireless and bridging.
It also covers some of the basic services and tools.
The slides can be found here -> Mikrotik Basics (16275).
I cover disabling ip services in my security class video, but until then for the port forwarding, you either need to disable ftp or change its port. You do this via ip -> services -> ftp. This goes the same for www traffic.
