Hi guys, I'm new here, but my adventure with mikrotik not started from today, I've got a little problem with configuration and I hope, that anyone can help me.

I use Mikrotik RB711 as Internet AP, which is connected to Mikrotik RB951Ui-2HnD and I would like to configure few things in it:

- Two Mikrotik devices should be in the same network (for example RB711 has 192.168.1.1 IP Address, and 951 should have ....1.2)
- I would like to have two DHCP Servers - one for WLAN, one for ETHERNET devices
- I need to have backup connection from USB, but I don't know how to configure it

Now the question is, how to configure it?

My configuration:

here i made a full class about mikrotik, theory + practice i hope you find it useful
you will find how to set it up from scratch and basic concept.
